Building AI agents

I build AI systems that think, act, and scale — from multi-agent orchestration to production platforms across LATAM.

About

I'm an engineer who builds systems that replace manual workflows with intelligent automation. Over 13 years, I've gone from real-time reservation platforms to orchestrating multi-AI agent systems that review code, optimize tokens, and debate architectural decisions across Claude, GPT, and Gemini.

At Apprecio , I lead automation initiatives across the product team — building AI agents that cut delivery time by 40% and optimizing microservice performance by 25%. I work across the full stack: React frontends, NestJS backends, PostgreSQL with row-level security, and Supabase for real-time multi-tenant platforms deployed across 6 LATAM countries.

Outside work, I build developer tools: Prism orchestrates structured debates between 3 AI models. Agentes Hub automates PR reviews with security-focused code analysis. Both reflect my philosophy: software should think for you, not just execute instructions.

My stack is TypeScript-first, AI-native, and production-tested. I don't prototype — I ship.
