Backend Software Engineer

I build the systems that move money — Go, Elixir and PostgreSQL in production at Stone. Nine years of backend work, most of it in payments and financial infrastructure.

For the past several years I've worked almost exclusively in financial infrastructure — payment platforms at EBANX and, since 2026, at Stone. Day to day that means Go and Elixir services talking to PostgreSQL, shipped through CI/CD, and watched over in Datadog and Grafana when things get interesting.

I started out in .NET at Agile Content, building REST APIs for Telefónica's streaming and OTT platforms. That's where I first ran into Kafka, Docker and event-driven architecture — and that grounding in distributed systems is still the part of the job I enjoy most.

I care about tests that actually catch things, services that are boring to operate, and code the next person can read without asking me first.
