I care about software that works outside the happy path.

I'm a Software Engineer from Brazil with 5+ years of experience building software, with a strong focus on mobile engineering.

My work often involves the less visible parts of mobile development: architecture, native integrations, offline synchronization, production debugging, performance and platform compatibility.

I enjoy taking ownership of difficult technical problems and following them from investigation to production.
