Here I have gathered several projects on which I have worked independently or collaborated. Not all projects are listed, only the most important and comprehensive ones.
This portfolio is intended to demonstrate my ability to work with a broad range of technologies, learn new tools efficiently, and apply them in practical software projects.
My current main tech stack consists of Python for backend and React (Web) / Flutter (Mobile) for frontend development but I've worked with various other technologies aswell.
The projects are categorized into Work, University, and Leisure.
