Hey — I'm Sam. Franco-American dev based in Guatemala, working mostly around Ethereum infrastructure and emerging market fintech.
Right now I'm contributing to a few Ethereum consensus and tooling projects:
- Lodestar (ChainSafe's consensus client, TypeScript) — working on verified request handling for the prover (PR #9203)
- Alloy (Rust Ethereum primitives) — refactoring transaction type organization (PR #3878)
- Submitted a notifier fix to Lighthouse as well
On the product side I built QuetzalPay — USDC payments for merchants here in Guatemala, on Solana. Remittances and local commerce are the use case. Also built DevScout, an Ethereum OSINT agent using ElizaOS + Nosana GPU that helps devs find contribution-ready issues across protocol clients.
Mostly write TypeScript, Rust, and Python. Interested in RWA tokenization, on-chain payments in emerging markets, and protocol-level infrastructure.
Open to contract work, protocol integrations, and grant-funded builds. Token comp is fine.
