Contributor to Microsoft's open-source 2D vector geometry library for CNC and laser-cutting applications.

I contribute to open-source software and am especially interested in TypeScript, developer tooling, testing, documentation, and data-intensive applications.

My current goal is to make consistent, useful contributions: reproducing bugs, improving tests, clarifying documentation, and delivering focused fixes that are easy for maintainers to review.

• Observability and historical data backfills for F1 Dashboard
• Testing, CI, and documentation across my public projects
• Consistent contributions to established open-source projects
