Héctor has spent his career building developer tools that change how entire ecosystems ship software. A computer engineer with 20 years of experience across infrastructure, mobile, and AI, he spent a decade at Meta working on open source development for React Native. Before that, he was one of the earliest team members at Parse (acquired by Meta/Facebook), where he shaped developer advocacy and built brand awareness for one of the fastest-growing developer tools of all time.

Today, he’s founder and CEO of Wallfacer, a cloud dev environment where Claude and Codex go from idea to PR while you watch — from a phone, a tablet, or any browser. Wallfacer pairs real Linux and macOS VMs — with your repo, services, Docker, Xcode, and the iOS Simulator — and a chat, diff, and live-preview UI, so engineers can plan, steer, and ship without ever opening a local IDE.

Before Wallfacer, Héctor was a Senior Software Engineer at Meta, where he spent a decade building developer tools and cross-platform frameworks like React Native and Parse. Originally from Puerto Rico, he’s now based in Scottsdale, where he still tinkers with systems for fun — from a backyard observatory for deep-sky astrophotography to a rooftop plane tracker.
