I build data-intensive products, developer tooling, and automation. I’m a co-founder of Signumi, where I work on company data, entity resolution, search, APIs, and developer infrastructure.
I maintain HarnessFacts, an open compatibility test suite for coding agents, and contribute upstream across developer tooling, infrastructure, Python, Rust, and .NET projects.
I tend to work on focused bug fixes, regression coverage, reliability issues, and developer tooling. I try to reproduce the problem clearly, keep changes reviewable, add tests where appropriate, and follow each project’s contribution policies. Over 100 meaningful contributions of mine have been merged.
- Data platforms, entity resolution, search, and large-scale data processing
- Python, TypeScript, Rust, Go, SQL, and modern web systems
- APIs, backend infrastructure, developer tooling, and automation
- Observability, reliability, testing, and maintainable software
- HarnessFacts — reproducible, evidence-backed compatibility tests for coding agents and their surrounding tooling
- Signumi — company intelligence and data infrastructure for European private markets
I’m especially interested in open-source issues where a focused fix, stronger test coverage, or clearer implementation can remove friction for other developers.
