    "summary": "For 15+ years I've built open-source real-time systems. In 2024 I co-founded Emilia AI, where the cameras, point-of-sale data and real-time signals restaurants already have turn into timely action for frontline teams, with humans in the loop. I wrote the first commit and most of the platform: real-time video ingestion and recording, computer vision and vision-language model pipelines, secure edge connectivity to cameras behind NAT, and the cloud platform on Kubernetes and AWS. In 2026 Emilia raised a US$1.5M pre-seed round led by Prosus Ventures, and we're now a team of 10. Before that I was open-source maintainer at Vocode (YC W23), founded WunderComm and ArtisanLabs, was CTO at RisePal, and spent 13 years as CTO of Sapian building open-source real-time communications. I organize the Supabase meetups in Medellín, and I've been part of the city's Linux and free-software community since the Asterisk days.",
