Since 2007 I have been designing, building and running systems for businesses. I stay with projects for the long term — some I have been looking after for nine years now. Modern tools, AI included, help me work faster; the focus on security and maintainability stays the same.
Get in touchA tourist social network with a mobile AR app. I build the API backend and admin interface and run the servers. In production for the ninth year.

In my spare time I build radios, measuring instruments and things around electronics. It is not just for fun — hardware accepts no excuses. Either it receives and measures correctly, or it does not. That is where you keep the instinct for when a solution is genuinely finished.
An SDR receiver in Rust for SoftRock and SDRplay. I/Q from the sound card, Si570 tuning over USB, panorama, waterfall, AM/SSB/CW/FM demodulation. My favourite project.

We talk through what you need and how you work today. No obligation, whether you have a full brief or just an idea.
You get an indicative estimate of the scope and price of the first version, and a proposal of what belongs in it and what can wait.
I build in smaller pieces and show them as I go, so you can try the system on real work before all of it is finished.
I take care of deployment, backups and security. The system then keeps evolving based on what real use shows.
Got an idea, or a system that outgrew its spreadsheets? Send me a few sentences about what you need — I will come back with an honest take on whether and how it makes sense. LinkedIn is the fastest way to reach me.
