Fran Méndez is a founder and engineering leader with 14+ years building and scaling event-driven systems, best known as the creator and steward of the AsyncAPI Initiative used by companies like Adidas, Adobe, LEGO and Walmart. He combines hands-on engineering (front-end, templating, and test automation contributions across AsyncAPI repos) with strategic governance work, helping Staff+ engineers and architects bring order to asynchronous architectures. Previously a Director of Engineering at Postman and senior technical lead at companies including Stuart and Hitch, he has repeatedly broken monoliths into resilient microservices and shipped developer-facing tooling. Fran pairs pragmatic developer experience improvements—SEO and UI refinements on the AsyncAPI website—with robust spec-level testing automation to keep standards reliable. He runs an EDA governance consultancy and authors a playbook for advocacy, translating open-source momentum into enterprise adoption. Based in Badajoz, Spain, he’s as comfortable writing CSS for docs as designing cross-organizational governance.
