Backend Engineer · Go (Golang) · Distributed Systems · Developer Tools
Backend software engineer with professional experience at Mercado Libre and Rappi, focused primarily on Go (Golang). I also work comfortably with Java (Spring Boot) and Node.js/React when needed.
I enjoy designing and operating complex/distributed systems, as well as building developer tools, CLIs, and small high-impact products. Outside work, you’ll find me reading about history or out hiking/trekking.
- Go services: APIs, background workers, event-driven flows, reliability at scale
- Distributed systems: performance, resilience, scalability, operability
- Developer experience: CLIs, internal tooling, templates, automation
- Engineering practices: testing, reviews, CI/CD, documentation, postmortems
Backend: Go · Java (Spring Boot) · Node.js
Frontend: React
Platform/Practices: REST · gRPC · Docker · CI/CD · Observability (logs/metrics/traces)
- Simplicity over cleverness
- Ownership: quality, docs, on-call readiness, postmortems
- Systems thinking: trade-offs, reliability, cost, performance
