About me

I've been hooked on coding since a young age, starting with Scratch, then Python, and eventually landing on web development. Today I build with React & Next.js, always eager to pick up what's next. I really enjoy music too, so I love building music-related apps whenever I can.

I am 17 years old and based in Gdansk, Poland. I speak English, Polish, and Ukrainian fluently. In school I also work with Angular, and outside of web development I'm comfortable with C# and .NET technologies like MAUI and WPF.

Started as a simple school project, it grew into a daily-used music player app. I built the frontend, while my friend made the backend. Songs use YouTube embeds for playback.
