Juan Osorio

Hola, I'm Juan Pablo.

Software & AI Engineer from Colombia.

I just wrapped up an incredible run at VTEX, where I built their Copilot AI — a multi-agent system using RAG pipelines to help merchants manage their e-commerce operations. It was everything I love: complex systems, AI at scale, and real business impact.

Before that, I spent years as a Solutions Architect and Engineering Leader, working with clients across LATAM and Europe. Large retailers in Colombia, Latin America, and France, plus dozens of enterprise deployments.

But the real story? I've been building side projects for 10 years. Appcitas started in 2015 and is still running. WalioAI is my 2026 bet on AI-powered lead generation. My wife Sara is an architect with 60k+ followers — I built her site at arquisara.com.

Based in Colombia. CS degree. Building in public.
