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, the cross-platform control plane for AI-driven software development. Wallfacer gives small teams the ability to direct and audit hundreds of AI coding agents with the same rigor Fortune 500 companies apply to human engineers — turning five-person startups into engineering orgs that operate like 500.

Before Wallfacer, Héctor was a founding engineer at Groupthink, building real-time AI collaboration tools in React and React Native. 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.
