I started as a backend developer in 2019 and never stayed in my lane for long. Today I work across the whole stack, and since 2022 I've been integrating AI systems and agents into real products. I care as much about the business problem as about the code.
My ambition is to build innovative, creative companies and technology. That's why I invest a lot of time in learning and in growing as a leader.
Simplicity is the ultimate sophistication.
A simple workout logger. No AI, no nonsense. Built for one-handed logging between sets, with clear progression metrics. It costs €3.99, which pays for the servers and not much else. Consider it a protein shake for my backend.
