What I am working on and what I have delivered

Projects

Ongoing and completed projects with role, stack and scope – so you can see at a glance what I actually do.

No logo wall, just concrete work: for every project you see which role I had, which stack was used and what exactly was delivered. The list grows with every project – ongoing ones come first.

How I work

Three principles that apply in every project

1

Understand before building

First the short technical assessment: what is the actual problem, where is the lever, what makes economic sense? Then the implementation.

2

Build instead of forwarding

You talk to the developer who does the work – no handover chain, no black box, clear status updates and early warning about risks.

3

Hand over instead of holding on

Code in your repository, tests, documentation and a deployment process your team understands. No vendor lock-in – your system does not depend on me afterwards.
