servers, email, monitoringI build software for companies, from the program inside a device to the phone app. Planning, development, operations and documentation come from one source. Since 2015.
“We have a device and it needs software.”
I write the software inside the device, and the desktop or phone program that goes with it.
“Our system is old, but it cannot stop.”
I build the new one next to it step by step. The old one keeps running and the data stays.
“The company runs on spreadsheets and paper.”
You get your own system with customers, invoicing, stock and reports.
“We need an app for our product.”
Built for Android and iPhone at once, for Bluetooth devices too.
“We need documentation for approval.”
I write the software documentation to the standard, for medical devices and for grant applications.
“What could AI do for us?”
I look for where it saves time and build it in there: recognition, counting, an assistant.
Expertise on the left, industries on the right. Pick one and the lines show where I have applied it.
Expertise
Industry
The program inside the device, and what connects it to a computer or phone: USB, Bluetooth, cable. Also the production-line checker and a safe updater.
Tools
Windows programs for measurement, monitoring and client records. They work without internet, in several languages.
Tools
The system behind it all, which stores the data and serves the website, the app and the devices. With payments and online invoicing.
Tools
Systems used from a browser: control rooms, business management, customer portals.
Tools
Android and iPhone apps from one codebase, for Bluetooth devices too. They work without signal.
Tools
Sound and image recognition, a built-in AI assistant, reports from the data you already have.
Tools
Servers, domains, email, backups and monitoring. Built from a written description, so it can be rebuilt or handed over at any time.
Tools
Automated checks after every change, and documentation to the standard for medical-device software and grant applications.

I build it in where it saves time, or notices what no person could keep watching.
Write a few lines about what you need, or call me. We talk it through and I write down what I will build and in which steps.
Yes. From planning to operations everything is in one pair of hands, so you have a single point of contact. On larger work I also work in a team, as on the OffConOn platform.
Yes. I often build the new system next to the old one, so the old one keeps running while the data moves over.
Yes: requirements, architecture, risk assessment, test plan and test report, to the standard for medical-device software, and the technical part of grant applications.
C# and .NET since 2015, Python since 2017, Rust and Go since 2021. Flutter and .NET MAUI for mobile, Blazor and Angular for the web, mostly PostgreSQL for data.
Two services I work on from the idea through to operations.
