What I'm looking for

I'm looking for remote work where I can build and evolve robust full-stack systems, solve complex integration and infrastructure challenges, apply strong DevOps and security practices, and keep experimenting with emerging AI technologies.

I've built and maintained applications across government, banking, and event technology for more than 20 years. Most recently, at ELZ Suporte Info for Sessionboard and Lennd, I maintained bidirectional integrations across 14+ event platforms using Node.js, AWS SQS, PostgreSQL, Redis, React, and TypeScript.

I've also led architecture, DevOps, delivery, and development work at Brazil's Ministry of Economy, INEP, and software factories. I enjoy turning complex requirements into clean, secure code while experimenting with AI workflows using LangGraph, Claude, LangSmith, RAG concepts, and MCP.
