Senior Blockchain Protocol Engineer
Senior Blockchain Protocol Engineer and Go engineer with 10+ years in software engineering across blockchain infrastructure, distributed systems, backend platforms, developer tooling, and production operations.
I turn protocol decisions into production code, tests, tooling, observability, and release workflows. My public work includes 1,100+ merged open-source pull requests, 300+ merged PRs to Ignite CLI, 200+ merged PRs to Trust Wallet blockatlas, the AtomOne ADR-004 Nakamoto Bonus implementation, and upstream contributions to Cosmos SDK and IBC-Go.
Core stack: Go, Cosmos SDK, IBC, CometBFT/Tendermint, gRPC, Protocol Buffers, REST APIs, concurrency, Docker, Kubernetes, Helm, GitHub Actions, Prometheus, and Grafana. I have also delivered Ethereum Layer-2 and zk-SNARK operator services at Hermez.
I am looking for remote Senior/Staff Blockchain Protocol, Blockchain Infrastructure, or Go engineering roles where I can own work from architecture and protocol implementation through production reliability. Available now from UTC-3 as a contractor or through an EOR. Brazilian and Italian citizen, EU work-eligible, and open to relocation within the European Union.
