/ About Me

I'm a dual student in Computer Science at DATEV eG in Germany, where I work as a software engineer building Spring Boot backends, REST APIs and Java-based services. I value clean code, thoughtful architecture and continuous learning.

Outside of work, I explore modern web technologies like React, Next.js and TypeScript through personal projects - from offline-first PWAs to Minecraft plugins. Building things from scratch is how I learn best.

When I'm not coding, you'll find me at the gym, gaming or diving into a good book. I enjoy staying active and always having something new to learn - whether it's a programming concept or a personal challenge.
