I build scalable Golang microservices and distributed systems for global platforms including Coinbase and Uber.
BrazilWhat I'm looking for
I've built and maintained high-security Golang microservices for Coinbase's Identity and Permissions systems, supporting migration to AuthZed and scaling throughput from 600 to 9,000 requests per second.
At Uber, I maintained logistics microservices for driver queue management, reducing technical debt through refactoring, improved test coverage, and dependency upgrades. I've also built Golang services, CLI tools, and Terraform infrastructure for Red Ventures and MTI.
Earlier at B2W Digital/Ame Digital, I delivered event-driven sales systems, POS applications, REST APIs, and CI/CD pipelines using Golang, Node.js, AWS, and DynamoDB. I continue to focus on Golang and distributed systems.
