Let's solve your challenges!

You, as a small business owner have too much to do already, let me help you with the technical challenges.

Custom Software Development
I build software that works the way your business already works. Instead of forcing you to change your processes, I create solutions using your existing workflow and terminology. This means less disruption, faster adoption by your team, and software that actually gets used. Perfect for businesses that need custom solutions but can't afford operational chaos during implementation.
System Migration & Modernization
Is your current system holding you back but you're afraid of the disruption that comes with upgrading? I specialize in seamless transitions that preserve your existing processes while giving you modern capabilities. Your team keeps working the same way, but with better tools that actually make their job easier.
Performance Optimization
When your website or system is too slow, you lose customers and revenue. I identify bottlenecks and implement solutions that can dramatically improve performance - like when I helped a client increase their Google indexing from 30,000 to 600,000 pages per week. Your users get a better experience, and you see better results.
Long-term Development Partnership
Rather than one-off projects, I work as your ongoing technical partner. As your business grows and changes, I'm there to adapt and expand your systems. This approach gives you stability, consistent quality, and someone who truly understands your business - not just your code.

Why Choose Me?

Unlike typical developers who force you to adapt to their systems, I design software that reflects how your business actually operates. No confusing jargon, no process overhauls - just efficient solutions using your existing language and workflows.

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. I've started a few myself: Plant care for Beginners, CRO-tool, Aloia CMS and several others.

I enjoy growing these projects as a business and I've seen success using my methods. I want to pass this success on to your projects, websites, and businesses to help you reach your goals.
