Martin Ferret

TypeScript expert focused on type-checking performance: why some projects are slow to check, how to measure it, and how to make them fast without losing type safety.

Lead Content Owner for the JavaScript and TypeScript certifications at Certificates.dev. Freelance fullstack developer working with TypeScript, Angular, Node.js and Spring Boot.

What I work on

  • TypeScript Performance Lab: measured, reproducible experiments on how fast TypeScript checks your types, including TypeScript 6 versus 7.
  • Open source: contributions to TypeScript's DOM types and documentation.
  • Les Rendez-vous TypeScript: a French-speaking online TypeScript meetup. The call for talks is open.
