At Mercado Libre and Mercado Pago, I build real-time data pipelines and backend APIs for platforms serving 65M+ daily users. I led the migration of 15+ production ETLs from Java to Go and reduced a critical pipeline’s memory footprint by roughly 40%.

I’ve also led complex data, migration, and integration delivery at Gaea Global Technologies, and built microservices supporting ML-driven applications at Abraxas Intelligence. I work across Go, Java, distributed systems, streaming, cloud infrastructure, and Spec-Driven Development with AI coding agents.
