Hey. I am Stefan, a freelance software developer with more 25 years professional experience, based in Berlin.


Are you looking for help? I'm at your service for contract work.

Experience

I spent the last 5 years working mostly as a frontend developer with React.js, JavaScript, TypeScript and Node.js for enterprise scale customers and startups. Before I was backend focused and worked with Ruby on Rails, Java, and C++.

I have cofounded two companies, worked as CTO and team lead, and have written two books in my field. I have coached individuals and teams. Also I am a Certified Scrum Master.

Availability

From 1. March 2022 I will be available for TypeScript/JavaScript work as freelancer, remote or in Berlin. I can help you with your next big project. Hire me or have a look at my resume or my GitHub account.
