Your error in, a working app out

Bug fixing

Errors, crashes, broken builds or strange behaviour in Vue.js, JavaScript/TypeScript or .NET apps. I find the cause, fix it and explain what was wrong.

Frontend features

New components, forms and pages in Vue.js that fit your existing code and design, connected to your API and responsive on every device.

.NET upgrades

Moving older ASP.NET applications to modern .NET, step by step and without breaking what already works.

Automated testing

Playwright end-to-end tests for your key user flows, plus unit and API tests, running automatically on every change.

$ man lukas

Practical developer, focused on results

I'm a web developer with 5+ years of professional experience on 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.
