Summary

Rockstar🎓
Top SchoolJason Desrosiers is an API Architect with 13 years of experience designing and hardening APIs, tooling, and developer workflows from startups to product teams. He has led API and JSON Schema efforts at Postman and currently shapes API strategy at Hyperjump Software, blending hands-on architecture with practical test automation. An advocate for specification-driven development, he contributes to prominent open-source projects like the OpenAPI Specification and the Understanding JSON Schema docs, improving tests and clarifying spec usage. His background as a technical lead who introduced CI/CD, gitflow, and AWS adoption—combined with a Master’s in Software Engineering—means he pairs strong engineering discipline with mentorship and long-term platform thinking. A less obvious strength: he balances deep protocol- and schema-level expertise with practitioner-level experience in teaching and coaching developers.
