About Kim

Senior software developer with 15+ years of experience, available part-time (one day per week + evenings/weekends).

I primarily work with the .NET stack, but have experience in other technologies including, but not limited to, Angular, Unity and iOS.

Besides development, I have also worked with DevOps, setting up pipelines, CI/CD and deployments using IaC.

On the cloud side, I primarily worked with Azure and the services provided there.

I have worked with global brands including LEGO, Grundfos, and Vestas, but also small local businesses, helping them either modernising old products/solutions or build new from scratch.

Typical projects I handle include:
- End-to-end development of web applications, APIs, and integrations
- CI/CD and Git-based workflows.
- Mobile apps
- Interactive 3D/Unity-based solutions

I also offer smaller fixed-price packages for limited-scope work, for example:
- Architecture / code review – 3 hours for 250€
- Debug & fix one critical bug – up to 4 hours for 300€

I look forward to hearing from you.
