    Software engineer in Finland with an MSc in Technical Mathematics and 15+ years of building developer tools and leading teams. I make numerical and GPU libraries easier to use correctly from code and from AI agents. My skills come from open-source projects with measured results: mathlib-mcp (API cards, pitfalls and a static checker for CuPy and nvmath-python, benchmarked on 26 GPU tasks) is at github.com/jarski/mathlib-mcp.
