About

I am a full stack developer with 4 years of experience building systems for regulated industries — credit platforms, customs software, compliance tooling and now healthcare — in Node, .NET, Go and React.

Most of what I work on has real consequences when it breaks: money moving, a government deadline, an audit trail. That shapes how I build — I care more about the system being correct and observable than about it being clever.

I also ship LLMs to production, with the Anthropic SDK and the OpenAI API, in cases where the output has to be auditable rather than merely plausible.

I am fluent in English and work comfortably with distributed teams.
