About Me

Tobias Termeczky

I'm a frontend developer who loves working in teams and isn't afraid to speak up when it matters. I like to dive deep into technical challenges on my own, and in recent projects I've taken on a leadership role in the frontend domain within multidisciplinary teams.

My main focus is on frontend frameworks like Angular & React, but I'm equally passionate about backend technologies such as Spring Boot & Java. New and innovative technologies give me energy and keep me eager to learn. Right now I'm at the forefront of agentic software development β€” leveraging AI-powered tools and workflows to push what's possible in modern software engineering.

I'm always looking for ways to grow β€” both personally and professionally.
