Senior fullstack engineer

I build complete products, from the React interface to the backend that keeps it running: APIs, queues, data pipelines and integrations, mostly on AWS. Remote, for teams in the US, Europe, Brazil or anywhere else.

Real Estate Management Platform

Multi-tenant property management SaaS for a US startup. I owned the backend pipelines that turn raw property data into enriched records, homeowner guidebooks, timed warranty alerts and a home maintenance planner, and designed and built much of the interface on top of them.

Personnel record

About

I like software that stays predictable after launch: interfaces that feel fast, APIs with clear contracts, queues and retries that absorb failure, and logs that explain what happened.

Studying Software Engineering with Applied AI at UNIPDS. I came to code from law, which is mostly why I read the docs to the end.
