I know you want to build software that's reliable, scalable, and actually helps your team move faster. To do that, you need a solid backend, a maintainable codebase, and tools that fit the way your business works.
The problem is that it's hard to focus on building a great product when you're stuck dealing with messy code, unreliable systems, or tools that don't quite fit. I believe you should be able to move fast without creating tech debt or bottlenecks.
I understand it's not always easy to ask for help with your architecture or internal tooling. That's why I guide you through my process and explain what I'm building—and why—every step of the way.
Here's how the process works: contact me to discuss your challenges, work with me to improve or build your backend systems, and ship faster with clean, scalable software that grows with your business.
So contact me and feel confident knowing your software is solid, your team is moving faster, and you're no longer fighting your tools.

Who am I?
Hi, I'm Roelof Jan! I'm a backend developer and business owner in Groningen and love growing websites and businesses. In the 9 years that I've been active as a software professional, I've learned a lot about starting and growing businesses.
