Engineering Leader & Full-Stack · Medellín, Colombia · Remote worldwide
I lead engineering teams, architect resilient systems, and build tools that empower developers.
12+ years shipping full-stack products — from high-traffic sports media platforms to esports systems, SaaS products, and open-source tooling. I specialise in technical leadership, developer experience, and the kind of architecture decisions that keep teams moving without letting quality slip.
Currently open to tech lead, full-stack, and engineering leadership roles.
