What I actually do

I shipped my first production system a few weeks after leaving school. That was 2017, on a Critical Operations project at COES. Nine years later the part I enjoy most has not changed: turning a vague client problem into code that runs in production.

I build backend systems with .NET and Node.js, and I write Angular or React Native when the stack calls for it. At Baufest I owned the SAP gateway microservice at Cosmos, a role that sits between the business owner and the technical team: translating what the client actually needs, building the API, and staying through deployment.

When something breaks I dig for the root cause first, then come back with options. A fix done well gets documented so it does not come back.

AI in the workflow, not on the slide

AI has been part of how I work for the last year, applied to real production tasks rather than to demos.

Internal skills

Reusable instruction sets that encode how this codebase is actually built, so the work does not restart from zero each time.

MCP servers

Tooling that connects the models to the systems I already use, turning a prompt into an action that lands in the repository.

Harness wrappers

Wrappers around GitHub Copilot that shortened iteration cycles on production tasks, from reading the diff to running the checks.
