My name is Jan, a freelance software developer and consultant based in Munich, Germany.
I’ve been creating software professionally for 15 years, and mainly focus on fullstack web development.
Whether you are a founder with no technical staff or an established team looking to bring in extra expertise: I both do hands-on development and handle the questions beyond the code – what to build, how to structure it, which trade-offs are worth making. To me, this bigger-picture thinking is where much of a project’s success is decided, and it’s something I genuinely care about. That said, I enjoy rolling up my sleeves and turning ideas into working software just as much.
Get in touch
Feel free to email a few lines about what you are working on and what you’d like a hand with.
We can take it from there – usually best over an initial call.
Don’t worry if you don’t have a spec yet or aren’t sure which approach is ideal. If you know where you want to go, I will help you shape a plan that fits and make it happen.
I am productive in a variety of programming languages and technologies all across the web stack; I’m also not shy of picking up new things.
Development
Features done right and delivered end to end, database to user interface: I shape what gets built, not just how, and am happy to join at any stage – from a greenfield project to an established codebase where I contribute from day one.
Architecture
Systems designed around actual requirements: I work through the concepts and structure – how the pieces fit, what scales, what sustains over time – whether that calls for building for the long haul or shipping a lean prototype fast.
Processes & Tooling
Low friction, high confidence: I believe the setup, tooling, and workflows a team relies on are as foundational as the code itself, so I craft them with care and thought to make daily work fast, dependable, and a breeze.
Practicalities
📆 Flexible on scope and hours, whether it’s for a one-off inquiry or an ongoing collaboration (from a few days a month to a full-time engagement)
🌍/🥨 Available to work remotely all around the globe, or onsite in Munich
🇺🇸/🇩🇪 Fluent in English and German
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 certainly 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
Jan’s superpower is his ability to combine deep expertise with a methodical, deliberate, and well-justified approach. This allows him to tackle almost any problem, making him our go-to resource for the toughest questions, whether they are about coding challenges, architectural decisions, or best practices. I recommend him without hesitation.”
Markus Schwedeler, Co-Founder NL Analytics
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.”
