Ruggero Rebellato

Building neobankless — self-custody banking for emerging markets.

We let people in Brazil convert BRL to USDC, earn DeFi yield on Solana, and spend globally with a card. No traditional bank required.

What I work on daily:

  • Solana programs in Anchor (vault system, share accounting, referral revenue sharing)
  • Rust backend services — Actix-web with double-entry accounting, event sourcing, CQRS
  • Banking-as-a-Service API — event-sourced Axum service with PIX rails, token swaps, inventory management
  • React Native mobile app with embedded wallets and KYC flows
  • Transaction indexer, BI dashboards, infra (Docker Swarm, Ansible, Prometheus/Grafana/Loki)
  • NFC hardware 2FA using NTAG 424 DNA for high-value transaction signing

Previous work:

  • OrionDB — low-latency key-value store in C with arena allocation and fine-grained locking
  • fmodel-rust — domain modeling library in Rust

Stack: Rust, TypeScript, Solana/Anchor, React Native, PostgreSQL, Redis, C
