Ship. Scale. Own.

Built Salsa's new hire reporting product end to end: an event-driven compliance pipeline that reports new hires to US state agencies, launched from 5 pilot states to all 50 for both employees and contractors.

Redesigned quarterly tax file generation from a synchronous, memory-bound process into a chunked async pipeline with retries and dead-lettering, validated against the previous output before cutover.

Owned the Go services behind user profile management at Mercado Libre. Every profile access on the platform went through them, across every Latin American country where Mercado Libre operates, at 500K requests per minute. Refactored the hot path for lower latency and added retries, circuit breakers, rate limiting, and caching to keep it resilient.

Worked on the document automation platform behind NowCM's debt issuance flow for European banks, turning bond contract generation from a slow manual legal process into an automated one. Optimized the generation hot path with Go concurrency primitives and built the CI/CD pipelines deploying it to Kubernetes.
