#### **Main pain points**
When JOIN approached us in 2018 during their early stages, they had ambitious plans for development and growth. However, they faced a significant hurdle in finding expert developers with specialized knowledge in their chosen technological stack, specifically React.js and Node.js. 

While these technologies held immense potential and were future-oriented, there was a shortage of qualified specialists in these areas. This scarcity of talent became a major pain point for JOIN as their ambitious growth plans necessitated deep expertise and qualified engineers to fuel their expansion.

#### **Needs and problems**
JOIN had a critical need to find a technological partner who could go beyond the traditional body leasing format and instead build a focused, expert team. Their primary objective was to establish a stable and long-term partnership with a provider who could offer not only dedicated resources but also deep product development expertise. It was essential for JOIN to collaborate with a partner who understood their vision and could contribute to their growth by providing a skilled team capable of delivering high-quality solutions.

#### **JOIN - strengths and advantages**

What was the challenge

Join_pic01.jpg

CircusStreet.png

#### Solution
React.js wasn’t a new solution to the Circus Street team. For instance, internal tools like the admin panels had been using React since the beginning of their organization’s life. The whole team at Circus Street was quite familiar with the technology.

However, we had a massive conundrum. How could we upgrade such a rigid app without impacting its performance for the end users? To tackle this issue, we engaged in an ideation process and outlined two potential paths:

1. We could **rewrite Circus Street’s entire application at once**. While this would be a holistic approach, it would also preclude any possibility of improving the application for a long time. This solution did not work for Circus Street because they had already established an expectation that their app would receive consistent updates. Their clients would not accept this type of approach.

2. On the other hand, we had the option of using the [Strangler Pattern](https://www.techtarget.com/searchapparchitecture/tip/A-detailed-intro-to-the-strangler-pattern)
, which allowed us to **migrate the application from AngularJS to React.js piece by piece**. Taking one step at a time, we would rewrite bits of Angular code into React and nest it within the old Angular code – which worked on React components. To achieve this, we used web components.



Gradually, we converted the entire application. We started with the smallest and least important components first and worked our way up to replacing the AngularJS core. As a result, the final product works perfectly.


**How we worked and build trust with Circus Street’s Team** 

At the beginning of the project, we only deployed a single team, made up of a combination of frontend and backend developers, plus a quality assurance engineer. Later, Circus Street wanted a team that was more integrated into their internal processes and workflows and instead created **4 separate teams**: one for frontend development, one for the backend, one for mobile development, and one Quality Assurance team. This change allowed us to **speed up the development process** and complete the project more efficiently.


Additionally, the process of integrating our team with Circus Street’s workflow was smooth and with no big delays. Not only was our team respected for their high-end technical skills, but they also possessed the soft skills required to get along with everyone on the client’s team.  

Communication isn’t just about sensitivity to the opinions of others. In a remote world, communication also needs to happen **smoothly in a technical sense**. We ensured that we addressed things like the sound quality and other mundane things ahead of time so that communication between our team members and Circus Street was always flawless.

Moreover, the higher-ups at Circus Street also respected our team’s abilities and as a result, they placed quite a bit of faith in our team from the beginning. We made decisions independently, and if something needed changing, we organized this ourselves without dragging down their internal workflows. Organized under a strong project manager, we were able to work with Circus Street’s team effectively.

**Achievements**
During the project we:

1. **Separated the mobile code from the desktop code** so that a specialist in each area of interest could take care of these matters themselves.

2. Took all the code written in AngularJS and **converted it to React.js and Redux.**

3. Wrote the code more flexibly than before, thus making it **easier to maintain** and modify in the future.

4. Created clear application logic through the **use of tests**. We also documented the code much more thoroughly than had been done before.

5. Made it **easier for new developers** to begin working on the project.


#### Results
With the 2022 Angular deadline looming, Circus Street needed to upgrade its application fast. They were gaining users every day, and couldn’t continue to maintain this user base with old and soon-to-be irrelevant technology in AngularJS.

From the technical side, we fixed any issues with AngularJS’ flexibility by **replacing it with React**. This also allowed us to split Circus Street’s mobile and web applications to make the application leaner and easier to modify.

Working in parallel with the old technology and implementing React code piece by piece was the best solution for Circus Street. After all, they had an in-demand platform with plenty of clients. They **couldn’t just stop maintaining the application** altogether while rewriting everything at once.

Every company’s ideal solution is different. This Circus Street case study exemplified our ability to adapt to the client’s needs and solve technological problems for applications with thousands of end-users. Reach out to us at hi@bitnoise.pl to learn how we might adapt to your use case.

A London-based online training platform that builds digital capability for global corporations

**Migrating from one technology to another** is a tall task for companies of any size. The larger the project, the more things can go wrong.

At Bitnoise, we like to take on large-scale applications and solve their issues using React.js. However, one of our clients’ foremost fears is adapting their project successfully to this new library while retaining the same level of service their clients expect.

In this case study, we’ll demonstrate how we cooperated with our client, Circus Street, to change their technology from AngularJS to React.js. As a result of our successful collaboration, Circus Street was able to open up a new path of product development **without harming the performance of its application** in any way.

#### About the Client
Circus Street is the only specialist provider of online training in digital skills **specifically designed for global enterprises**. Circus Street partners with their clients to design learning paths that meet the individual needs of their business. Programs are delivered through an **LMS friendly** platform that houses an online library of 100+ lessons, all made with Circus Street elements that make the knowledge stick. The courses are created with; scriptwriters to simplify complex topics, award-winning animations that are entertaining and educational, interactions and assessments to embed knowledge, and dynamic presenters that keep learners engaged. The platform offers translated video captions and assessment questions, integrates with LMS’s, adopts single-sign-on, and automates management tools.

#### Needs and problems
Originally, Circus Street reached out to us to get help maintaining their main web application. At the time, it was running on AngularJS. 

During our initial technical consultation, we both realized that one sticking point was causing Circus Street a lot of harm. AngularJS is an **old and static technology**, any support for this library was soon to end in 2022.

Circus Street needed a solution that would allow them to introduce new features to web and mobile apps more quickly. The solution also needed to be flexible enough that Circus Street could make the switch without inhibiting its ability to deliver a quality experience for its clients.

#### Main pain points
After our initial consultation, we outlined the key issues that Circus Street’s current app was suffering from.

1. The application was **monolithic**. And compounding this problem was the fact that they were running an old version of AngularJS instead of a recent version.

2. Since Circus Street applied the same code to their mobile and desktop applications, everything was interconnected. That meant that instead of working on separate solutions for their web and mobile applications, Circus Street needed to **fix both apps at once**.

3. The main application’s code was structured in an excessively rigid way, thus **limiting our flexibility**. Applying changes and fixes to the code took longer than it should have.

### Team augmentation
As the first step, we selected experienced React.js developers, who were suitable to join the project. We set up calls with the client and allowed them to have in-depth conversations with our engineers. Once the technical and cultural fit was established, we ramped up and started our work in a couple of weeks. 

Bitnoise team consisted of two developers with extensive backgrounds in React.js and TypeScript as well as excellent language and communication skills. The engineers quickly started working directly with Prescience staff, including the CEO and CTO. In this case, Project Managers or SCRUM Masters were not needed, thus reducing the total overhead.

###

### 
Needs and problems
Prescience approached us with several requirements on different levels. 

- Most pressing was the need to complete a new version of the partially-completed frontend application in React.js, which was to substitute an existing version created in Vanilla JS.

- Furthermore, Prescience team had been historically focused on the backend, databases, and complex functionalities, and additional skills were needed to scale, improve and refactor the frontend.

- Finally, in several areas, React.js had been used in its raw form, and a need was identified to use several open-source libraries and battle-tested tools.

Enhancing fashion e-commerce 

Technologies our developers used

Property_1_FashionEcommerce.png

Scaling React.js team for Europe's leading fashion e-commerce

Europe’s leading fashion retailer

This case study focuses on a **multinational fashion retailer** that faced challenges related to the digitization and development of e-commerce. The company had to scale its online sales platform quickly while ensuring that its operation remained efficient and customer-friendly. This required finding, hiring, and implementing **frontend** programmers into the project. We stepped in to help by providing specialists with engineering education and experience in agile technology project management methodologies.

#### **About the Client**
Our client is a large fashion retailer that offers high-quality fashion products for men, women, and children. The company is known for its affordable prices and its focus on sustainability and responsible sourcing. It has stores in several countries in Europe, including Germany, Belgium, and the Netherlands, and has also expanded globally to Asia and Latin America. 

- Number of employees: over 50000 

- Annual revenue: 8bn USD 

- Physical locations: 1400 stores in 18 countries 


#### **Needs and Problems**
In recent years, there has been a huge increase in the demand for **digitization** services in the clothing industry. Having an online store is now a crucial aspect of running a successful fashion business. However, building a user-friendly online platform that can handle a large volume of orders and data flow is a complicated process. 

Our client, one of the largest multinational fashion retailers, had to scale its online sales platform quickly without disrupting its operation and without discouraging customers. The real challenge was to effectively find, hire, and implement frontend programmers into the project without making any mistakes.



FashionEcommerce_pic01.jpg

#### **Solution**
The Bitnoise team leverages our expertise to turn the client's vision into a reality. We started with a discovery phase to define the product roadmap, identify user personas and needs, and define the application's functional and technical requirements. We then moved on to design and development, building the platform from scratch with the features identified during the discovery phase. Throughout the process, we collaborated with the client to ensure that the platform met their expectations and was aligned with their business goals.

The main challenge was to ensure precision in both the business and technical aspects of the project. **We did it using TypeScript and our development team, with the strong assistance of the Head of Technology, successfully developed the following:**

- **Implementation** of an innovative tandem application flow with several scenarios depending on how the partner is selected.

- **Matching algorithm.** The main challenge was to create a tool that will collect data from end-users who completed surveys with dozens of questions starting from the number of hours they want to work to their skills and characteristics. The matching algorithm task is to score candidates' answers and by using the weighting points match them in tandems for given job opening. The score is expressed in %, the higher the number the better candidates tandem is fitting the role.

- **Chat between users.** As we progressed with the project, we encountered an issue with the chat between users. The problem with available free (or cheap) solutions was that they only allowed users to talk with operators logged into the panel. We needed a solution that allowed users to talk to each other within PairToShare. We used **React** and created an NPM package for chat UI and a server based on  SocketIO.


#### **Results**
After several iterations, we helped launch the platform that streamlined PairToShare's recruitment process and expanded their digital presence. The platform allowed job-sharing seekers to find job-sharing opportunities and their ideal tandem partner through a research-based matching algorithm. They could apply directly to companies from the platform while enjoying anonymity. For companies, PairToShare's Tandem Recruiter automated the integration of all job postings that they wanted to make flexible. This increased the pool of top-qualified candidates and positioned their company as a desirable employer. The platform runs under the highest IT security standards and is GDPR compliant, with no integration effort required.



#### **Conclusion**
PairToShare's innovative solution has revolutionized the recruitment process for both job-sharing seekers and companies. Our team is proud to have helped PairToShare achieve their business goals and improve the lives of job-sharing seekers.



**Frontend**

- Next.js, TypeScript, MUI


**Backend** 

- Nest.js, TypeScript, Prisma, Postgres




- Innovative application flow with varied scenarios depending on partner selection.

- Matching algorithm that scores candidate answers and matches them in tandems for a given job opening.

- Chat system developed using React and SocketIO to enable users to talk to each other within PairToShare.




HR-Tech solution

Property_1_PairToShare.png

An MVP for a German HRtech that uses algorithms to help candidates land a job

PairToShare

PairToShare is a platform that utilizes a matching algorithm to assist those seeking to share a job in finding the most suitable partner for their job-sharing arrangement.

In today's fast-paced world, work-life balance has become increasingly important for employees. The demand for flexible work options has led to the rise of job-sharing, where two or more people share the same full-time position. PairToShare is a revolutionary tech-recruiting solution that caters to the needs of job-sharing seekers and companies alike. It heads to address the market worth of more than (data) and therefore needed to work smoothly on both web and mobile applications. What technology and problems to solve stood behind this project. We explain it in the following blog-post.

#### **About PairToShare**
[PairToShare](https://www.pairtoshare.com/)
 is a platform that provides a research-based matching algorithm for job-sharing seekers to find their ideal tandem partner for sharing a job. The platform also allows job-sharing seekers to apply directly to companies from the platform while offering anonymity. For companies, PairToShare's Tandem Recruiter automates the integration of all job postings that they want to make flexible, increasing the pool of top-qualified candidates and positioning their company as a desirable employer.


#### **Main pain points**
The majority of companies have not yet incorporated job sharing into their recruitment processes. The jobsharing hub, a consultancy agency and the founder of the PairToShare startup, has advised many of them on introducing the concept of job sharing internally and helped them recognize this approach as a recruitment driver that can take them to the next level. Now, a lot of these companies are ready to offer job sharing opportunities to external applicants, which can only be achieved through scaling and automation. As the market leader in the area of job sharing, the jobsharing hub has invited Bitnoise to collaborate on the technical development of a new platform called PairToShare.

#### **Needs and problems**
To address these challenges, our developers and PM team worked closely with the client to identify their needs and expectations. Thanks to that we recognized the importance of creating an application from scratch to address all PairToShare's needs. We worked closely with the client to identify the expected features, which included:

- a job board,

- job search,

- user profile and login,

*We are experts in consulting processes, which is mainly an industry based on face-to-face cooperation with clients. However, as important as this is, the solution has its limitations. If a company wants to scale in the external recruitment market, job-specific matching creates too much effort. In the fast-changing digital world, we needed to smoothly translate our 	business experience into a digital solution. This is where Bitnoise came in and provided a helping hand. They interviewed us about our needs and business expectations, and provided us with the technological solution.*

During the development of React Scheduler, we came up with a solution that encompassed the following aspects:

#### Extensive customization

React Scheduler was engineered with a profound emphasis on adaptability. Developers were afforded the liberty to tailor the scheduler to their specific requirements, from the visual elements to core functionalities. This encompassed zoom levels for granular viewing, multilingual support, and a flexible configuration system to fine-tune the scheduler's behavior.

#### Interactive User Experience
The user interface of React Scheduler was methodically designed in three segments:
- Resource Management: A sidebar listing resources, complemented by a search function and pagination, laid the groundwork for effortless resource navigation.
- Navigation and Filters: The header featured intuitive navigation controls and optional filters, granting developers the autonomy to enhance or simplify the user experience as needed.
- Dynamic Grid System: The centerpiece of React Scheduler was its interactive grid, displaying tasks with detailed tooltips and complying with accessibility standards to ensure inclusivity.

Throughout the development phase, Bitnoise demonstrated an unwavering commitment to user engagement, continuously refining the component based on user feedback.

### Results

React Scheduler has provided a robust and adaptable tool that caters to the complex demands of scheduling within React-based applications. It has markedly reduced development time and elevated the end-user experience through its responsive and seamless interface.

#### Bitnoise's dedication to innovation and community

The journey of React Scheduler from ideation to execution exemplifies Bitnoise's dedication to solving practical development challenges. Their commitment to community-driven innovation has not only filled a void in the open-source ecosystem but has also empowered developers globally to create more dynamic and efficient applications.

In the intricate world of software development, Bitnoise identified a critical shortfall within open-source resources for scheduling in React – a deficiency that encumbered developers from effectively building software to manage resources such as people or meeting spaces. This gap not only impeded the workflow but also prolonged project timelines, and required a modern, efficient solution.

#### Bitnoise's initiative: the idea behind of React Scheduler

With a wealth of experience in React and TypeScript, Bitnoise set forth to construct a solution – the React Scheduler. This innovative tool was conceived to transcend the limitations of conventional DOM-based solutions, offering unparalleled performance and a contemporary approach to resource management on a grid-based interface.
