Javier Chi Ortíz
AI Software Engineer
The person behind the code
I'm a senior software engineer who builds products with AI. Right now I'm building Brania, an AI-powered platform, as a Senior Full Stack Engineer: I design and ship complete features, from frontend to backend.
In parallel I run Lab2Next, my own SaaS for clinical labs. I designed, built and launched it on my own, and I keep it running in production, from product and infrastructure to support.
Over 6+ years I've shipped production software for clients in the US and Latin America: data-intensive portals, multi-tenant platforms, and a legacy BI migration to Spark + Superset. I work mostly with React, Next.js, TypeScript and Node, and I own the full cycle, from spec to post-launch maintenance.
Away from code I practice Shotokan Karate (2nd Dan) and play exploration and fantasy games. Karate and software taught me the same things: clarity, discipline and getting a little better every day.
