About me

Backend engineer at Mercado Livre, writing Go services that support millions of daily package deliveries across Brazil. Before that, three years at Dell Technologies building incident automation for its global support infrastructure.

I care about distributed systems, performance and clean architecture, and I like to measure things before I believe them. On the side I build small open-source tools in Go and Java.

Outside of work: music, cinema and surfing.

Highlights

  • pprof_advisor: offline Go CLI that ranks pprof hotspots and gives a statistical verdict on whether a patch actually helped
  • go-router: dependency-free HTTP router for Go on a patricia trie, with lock-free lookups
  • java-p2p: UDP peer-to-peer file sharing over a DHT of super-nodes, written from scratch in Java 21
  • memorization: flashcards app built with Spec-Driven Development, running on AWS
