Senior engineer (13 years) based in Amsterdam — TypeScript, React, Next.js, and reactive architecture. Currently creating AI-driven automation and developer tooling.
What I'm doing
- Building tools instead of demos (e.g. mini-rag)
- Exploring gaps in developer tooling: live debugging for RxJS/observable streams, and contract sync across stacks.
- 13 years shipping software and leading engineering teams — most recently building a custom MVVM framework and no-code editor tooling.
Side-Interests
- Formal ontologies & knowledge representation.
- Building tools for thinking with graphs.
