Looks like you have JavaScript disabled. For the full Twine experience, you will need to re-enable it.

I’m a full stack developer based in Warsaw with hands-on experience building web applications using JavaScript and Python, from responsive frontends (HTML5, CSS3, Bootstrap) to RESTful backends with Node.js/Express and Flask. I enjoy creating practical features end-to-end, including secure route handling, clean API design, and user-friendly interfaces. I also bring a QA-focused mindset from part-time work as a tester, where I document bugs clearly and collaborate on validating fixes for pre-release builds. On my projects, I’ve combined automated testing and real browser flows using Jest, Supertest, and Playwright, and I’m always aiming to deliver reliable, privacy-aware products that behave correctly even through refreshes and edge cases.…I’m a full stack developer based in Warsaw with hands-on experience building web applications using JavaScript and Python, from responsive frontends (HTML5, CSS3, Bootstrap) to RESTful backends with Node.js/Express and Flask.
