At Mercado Libre (Mercado Crédito), I own core Java and Spring Boot backend services, from design and development through production and incident response. I made four critical payment flows safe to retry when they run concurrently.
I also fixed event-ordering and version-check bugs in an event-driven projection pipeline, then cleaned up a backlog of about 1.4 million stale records. I design REST APIs for other teams and review teammates’ changes.
At Borderless Software, I built backend services for a US client’s subscription-management platform using C# and .NET Core on AWS. I managed infrastructure with Terraform and added OpenTelemetry distributed tracing to help diagnose production issues faster.
I co-founded ZEST, a B2B operational-intelligence platform for restaurants, and built its product from scratch. I led its architecture and security, including database-level tenant isolation and a transactional outbox that keeps heavy reporting off day-to-day actions.
