My name is Jan, I am a freelance software developer and consultant based in Berlin, Germany. I’ve been creating software professionally for more than a decade, and mainly specialise in fullstack web development.

If you are interested to work with me, please reach out via e-mail. I’m open to all kinds of projects and inquiries, and I’m available to work in Germany or internationally (i.e., remotely). To kick off a chat, you could let me know what you are up to, and which kind of help you are looking for. We can then take it from there and figure out the rest together.

I am productive in a variety of programming languages and technologies of the web development stack, and I’m also not shy of picking up new things. I work hands-on, advise on all technical or architectural questions that come up, and support you throughout the entire lifecycle of your project.

My primary driver is to create great software products that are meaningful for the people who use them.


Implement features end-to-end, and take part in the development process from start to finish.

Design tech stacks based on sensible requirements, and structure software so that it sustains and succeeds in the long run.

Build tooling to streamline technical processes, for better productivity and more reliable systems.

What my clients say

Jan’s software development skills alone would make him a great addition to any team, but what sets him apart from other developers are his complementary skills. For complex projects, Jan takes care of the entire software development lifecycle – he’s comfortable gathering requirements, turning them into a clear plan of action, and then driving the project to completion. He has an excellent attention to detail and is also passionate about feature design and usability.”
Michael Lynch, Founder TinyPilot
We’ve been working with Jan for about six months now, and I haven’t met many developers on his level in my 24 years of professional experience. He is so easy to talk with, quick to understand the matter, and to come up with solutions that it outclasses many of my experiences with other senior developers. We might have hit his sweet spot with our tech stack, but I would blindly hire him for any project that remotely meets his background.”
Eckart Burgwedel, CEO Uberchord
Working with Jan is amazing. His programming work is of top-notch quality and done remarkably quickly. Our meetings always felt very productive, because with him around, suddenly everything seems to become technically possible. And on top of that, he’s also a really nice guy who’s fun to work together with.”
