Production-Ready Mendix Application
Scalable, high-performance and tailored to your business needs.
Many Enterprises Work With Mendix But Can't Achieve The Quality
And Development Speed That The Platform Was Built For
Here's what some of my Mendix projects look like in action:
Bloated development cycles by slow-moving
international software firms.
Quick completion of required functionality
according to milestones and agreed price.
Technical debt produced by large (offshore) teams
with questionable Mendix expertise.
Lean, expert execution by
a certified Mendix specialist with a proven trackrecord.
Many hours wasted in long meetings with project managers,
account managers, and internal stakeholders.
Clear milestones, transparent pricing
and tangible results
Budget overruns driven by bureaucracy, inefficiency,
internal politics and vague deliverables
No nonsense — just working software and fast

Hi, I'm Stefan
Almost 10 years of experience in Mendix. I have been working on around a 100 Mendix applications for large companies across different industries and in various parts of the world. I have been working both on-site and fully remote for many end-clients.
I take full ownership of every project I work on, from first idea to final deployment, ensuring each stage delivers the best possible outcome by leveraging the full power of the Mendix platform.
Whether it’s designing scalable data models, or integrating complex systems, I stay at the cutting edge of what Mendix can do, so you get future-proof, high-performance applications without the overhead – and fast!
I work with companies that:
- Already understand the potential of low-code
- Have a vision in mind, but need help executing it
- Are ready to test, refine and deploy quickly
- Want a Mendix application that fits into existing workflows
I’ve been working with Mendix since 2017. Here are some highlights:
- Rescued a failing Mendix – SAP integration project.
- Built and delivered a mailroom module in Mendix for a large Dutch public sector consisting of 14 organizations.
- Created a framework for quickly developing native mobile applications in Mendix for a Texan oil and gas company.
- Built a money guide wizard for a Dutch municipality.
- Quickly delivered a fully functioning mobile application dedicated towards time registration within two weeks.
- Completed an emergency delivery of a Mendix application dedicated towards receiving measurement data from the Dutch railway system.

I had the pleasure of working alongside Stefan at Bonjoy, where he quickly established himself as one of the sharpest developers I’ve ever collaborated with. He’s not just a Mendix expert, he’s a full-stack problem solver who consistently delivered clean, scalable solutions across multiple projects at once.
Whether juggling complex client requirements, building out role-based workflows, or collaborating with business teams under tight deadlines, Stefan brought clarity, speed, and technical excellence every time. If you need someone who can own delivery and elevate your dev team, he's that guy.

Stefan is a real expert in his work. He always works with full determination in the projects we had. Stefan has a great eye for making the best solutions and fixes and works fast. In the time he was part of my team he was a pilar for me and the team.
He was someone we could really count on and a nice person to work with. He always went the extra mile to make sure our application was functioning right even out of working hours. I really appreciated Stefans work and him as a person. Any organization is lucky to have him!

Senior Test Engineer
With Stefan’s in debt knowledge about Mendix, he immediately started with creating a smart and working domain model as strong base to build all functionality on. This included clean and simple representation of the business flows, which was not easy with the comprehensive requirements demanded.
During this process he was constantly checking in with the client to see if adjustments where needed. These small iterations also gave him a deeper understanding about the true needs of the client. In time, this knowledge created a base for helping the client in advising them on more possibilities within the scope of the new functionality. Also, when you truly understand a task, you can be creative. This was the case here. So, I would say that Stefan did a really good job in translating the requirements into valuable business tools.

Stefan did a great job in trying to understand our needs. The certified institutions that work nationally still received a lot of physical mail. For them, the mailroom functionality that Stefan built, is of great value. He also made it so that the functionality has a lot in common with a real post office where it is as convenient as possible to distribute the mail to the different receivers.
Mail for all the teams across the country arrive at one central point from where they now can be easily uploaded and distributed to client files. The responsible agent is then notified by the system that a mail item has been added to the client's file and has to verify the item before it is finally added to the client's file. In this way, Stefan has made sure that every mail item is handled quickly and correctly.
