Previous work

I didn't just study EDA.
I set the standard.

AsyncAPI is the open specification for event-driven APIs. I created it, grew it into an industry standard, and helped bring it under the Linux Foundation, where it continues to be maintained and adopted worldwide.

When I first learned how AsyncAPI came to be, I knew Fran was someone I wanted to connect with and collaborate with. His deep expertise in event-driven architecture has not only shaped an industry-standard specification, but also cultivated a thriving community around it. Whenever I need to have a deep, insightful conversation about event-driven systems, Fran is the person I turn to.

Straight talk.
No noise.

I transparently share the journey of building Commune: the wins, the setbacks, the product decisions, and the human side of it all. Sometimes EDA, sometimes mental health, always honest.
