$ man lukas

Practical developer, focused on results

I'm a web developer with 5+ years of professional experience building and maintaining a worldwide time slot booking platform used by thousands of customers every day.

I specialize in the frontend and in bug fixing: finding the real cause of a problem, fixing it cleanly and making sure it doesn't come back. I work across the whole stack, from Vue.js and TypeScript in the browser to C#/.NET, SQL and Azure on the backend.

I'm self-taught. I started programming on my own before turning it into a career, and I still enjoy learning new things.
