What I'm looking for

I'm open to remote opportunities where I can contribute to large-scale backend systems and distributed architectures.

At Compass UOL, I develop backend applications for Natura's omnichannel delivery experience, serving customers and consultants across Latin America. I build features in a shared BFF to bring together data from microservices, AWS Lambda functions, and third-party APIs.

I also designed a store-change monitoring pipeline that improved production observability while reducing unnecessary Lambda executions and storage costs. Across 16 production applications, I led a test coverage initiative that raised coverage above 90% using Jest.
