I build AI
that runs
companies.
AI engineer across the full stack. Production RAG pipelines and multiagent systems with Claude and LangGraph, exchange infrastructure at NEMO LATAM, and lead engineer at Qolca, a software studio serving companies across Latin America. My work runs on WhatsApp and Meta Business APIs, and in vision pipelines that write straight into client ERPs.
Three things I do, end to end.
- I.
AI Agents.
Production RAG pipelines and multiagent systems. LangGraph orchestration across Claude, OpenAI and Gemini, pgvector retrieval, context engineering, and MCP integrations that connect agents to client tools. Token streaming over SSE and WebSockets, so answers render as they generate. Running for real clients, not demos.
- II.
Product Engineering.
End to end ownership: scoping, architecture, ship. React, Next.js and React Native on the front, Django, FastAPI and Node on the back, real time WebSockets, payment integrations, and pytest plus Vitest coverage on the flows that matter.
- III.
Infrastructure.
Production AWS (EC2, RDS, ALB, CloudWatch) with Docker, Kubernetes and Terraform. I provisioned and ran NEMO LATAM's exchange infrastructure from scratch at 99.9% uptime in a 24/7 financial environment, and shipped the first VISA card integration on a Peruvian crypto exchange.

Building AI?
Let's talk.
I lead engineering at Qolca, a software studio, and work from Lima with full US overlap in native English. What I ship: production RAG and multiagent systems, WhatsApp and Meta Business API products with per message billing, and LLM vision pipelines that write validated readings into client ERPs. Everything on this page is running in production. If you are building in that territory, write to me.
