Your error in, a working app out

Bug fixing

New components, forms and pages that fit your existing code and design, responsive on every device.

.NET upgrades

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

Connecting your app to payment gateways, CRMs, maps or your own backend endpoints in .NET.

$ 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.
