About me
Based in Frankfurt am Main, I've been building web products since 2015. I work closely with product teams to turn ideas into fast, accessible, and maintainable software — from early MVP all the way to production scale.
My background is in computer science (TU Darmstadt, 2014), and I've spent the last several years specialising in React ecosystems and serverless AWS architectures. I care deeply about developer experience, documentation, and shipping things that don't break at 2 AM.
When I'm not at my desk, I'm usually cycling along the Main river, reading about distributed systems, or arguing about coffee.

What I do
End-to-end product development or targeted expertise — whatever your project needs.
Backend & APIs
REST and GraphQL APIs in Node.js. Serverless AWS Lambda functions. Reliable, well-documented, properly tested.
Cloud Infrastructure
AWS architecture design, Terraform, cost optimisation. I've migrated monoliths to cloud-native and lived to tell the story.
UX Consulting
User flows, design systems, component libraries. I bridge the gap between design files and production code.

What clients say
"Lukas delivered the MVP two weeks ahead of schedule. The code quality was exceptional — our internal team had no trouble taking ownership after handoff. Would hire again without hesitation."
"Working with Lukas felt like having a senior engineer and a product manager in one. He asked the right questions, caught edge cases we hadn't thought of, and shipped a rock-solid platform."
"GDPR compliance for healthcare is notoriously difficult. Lukas not only understood the requirements but proposed architecture solutions I hadn't considered. Clean, documented, secure."
