Two decades helping engineers learn, connect, and ship.
Currently leading developer relations and AI Labs at Rootly, building open-source tools and research to advance reliability engineering in the AI era.
Previously co-founded Holberton School, a venture-backed developer education startup that trained thousands of software engineers across 25 countries, backed by Jeff Weiner, Jerry Yang, and Solomon Hykes. Before that, senior SRE at LinkedIn, where I co-designed a patented self-healing infrastructure.
I also founded while42, a developer community of 3,000 engineers across 40 cities. I write for TechCrunch and The New Stack, speak at conferences like SREcon, and help SRE and platform teams navigate the AI ecosystem through articles, talks, and open-source projects.
