Building production AI systems that don't fall over.

STATUS — OVERVIEW
GHLIMD
COVER LETTER
/ INTRODUCTION

Application builder across the full stack — frontend, backend, architecture, infra, auth, databases. AWS certified. 15+ years shipping software that works in any environment, not just “on my machine.”

Right now I'm most interested in the part of AI that nobody talks about: making LLM-powered systems actually survive production. Agents, RAG pipelines, tool use — easy to prototype, hard to run reliably under real traffic, real money, and real compliance. That gap is where my architecture and infra background earns its keep.

On hiring: some teams evaluate engineers purely by hourly cost. I prefer the view that good tools require proper investment. The difference between average and exceptional developers isn't the rate — it's the years of headaches you don't have to deal with.

Currently: leading engineering at T-Pro (healthcare dictation software — regulated, high-stakes, real users), building a personal finance app on the side, and going deep on agent orchestration and LLM cost engineering.

Previously: architected systems for live video streaming at Brazilian scale, built Android apps at Buscapé's innovation lab, did information security at CIPHER.
