I'm a fullstack developer based in Brazil, working mostly on backend systems, APIs, and cloud infrastructure. I like taking a feature from a vague business requirement to a service that actually holds up in production — API design, data pipelines, async processing, and the AWS plumbing that connects it all.

I've spent the last few years building backend systems in Go and Python, with React/TypeScript on the frontend when the project calls for it. Most of my day-to-day work is REST APIs, serverless pipelines on AWS, and microservices that need to process data reliably at scale.

Recently I led the backend for EnergiQ Hub, a B2B2B energy management platform, and spend a good part of my free time going deeper into distributed systems fundamentals — load balancing, consistent hashing, rate limiting — usually by implementing them from scratch rather than just reading about them.

I'm currently based in Lauro de Freitas, Bahia, and hold a background in Civil Engineering, which is where the interest in systems that need to be structurally sound in the first place probably comes from.
