With this company I worked on:

• YouMap - Whilst working on this project, I got to help built some nice and accessible user interfaces and also help my teammates integrate many useful tools into the project.
• Jazzed - When I joined into the team, this project just needed some adjustments and a couple more features to be finished, which I gladly did. I also helped to slightly improve the developer experience in the small amount of time I had.

With this company I worked on HPN Calculator - this was a quick project built to help tax payers in Poland with their taxes. The project was built from ground up to be accessible, fast and precise. What we mostly focused on were the complexities of how the taxes should be calculated and how the different types of tax reliefs apply into the equation. We also wrote tests to prevent any regression errors. In the end the client was very happy to receive the project so quickly put together.

Whilst working for this company, I was asked to help with a couple of projects. The most notable one was Katalog Podmiotów Publicznych. The app was designed to assist in management of public entities, which required a lot of data filtering, sorting and other complex operations. We've managed to achieve this by designing an adequate architecture for completing such a task.

With this company I worked on:

• Gabinet.gov.pl - When I joined the team, what we mostly focused on was improving developer experience, which left a lot to be desired. We worked on a better way to handle many complex forms in a more unified and structured way. Proper streamlining of most complex parts of the code improved the overall performance of the application. We also worked on integrating it with the Backend API and wrote tests to prevent any regression errors.
• Portal.zdrowie.gov.pl (Internal project) - A CMS-like project designed to allow quick adding, removing and editing of articles into the site. The project was built from ground up to be accessible, fast and easy to understand. In the end the client was very happy to receive the project so quickly put together.

The first project I got to work on professionally. Whilst learning the ropes of collaborative work, I also got to experience the struggles of inheriting a somewhat badly managed project and bringing it back to life. What we managed to achieve is to greatly increase the performance of the application and the improved the developer experience, which subsiquently increased the speed in which new features got built.
