Remote worker with 2+ years of experience - Last seen 13 days ago

I’m a software engineer from Brazil, with 2+ years of experience building scalable, impactful solutions.

Fluent in Portuguese and proficient in English (C2), with intermediate Spanish, I thrive in multicultural environments and am always eager to learn and adapt.

At my most recent company, I’ve introduced new services from scratch, taking full ownership of both the architecture and implementation of a tileserver and the data processing pipeline to feed our map solutions. These efforts have directly improved system performance and reliability while reducing costs.

My greatest achievement came from analyzing Mapbox’s billing structure and refactoring the frontend architecture to cache the map entirely on the client side, with this simple change, I achieved a 90% reduction in API costs.

I specialize in TypeScript, React and NestJS. With hands-on experience in Docker, Cloud platforms, and WebSockets, I focus on delivering efficient, scalable systems and solving complex technical challenges.
