Senior Blockchain & Full Stack Engineer
Blockchain and Full Stack Engineer with five years of experience designing and shipping production DeFi protocols, on-chain financial infrastructure, and the full-stack systems around them. I own a protocol end-to-end — smart contract architecture, security auditing, frontend integration, and production infrastructure — without handoffs introducing risk. Logic errors in this domain are financial exploits, not bug tickets. That shapes how I work: threat-model first, test thoroughly, audit before launch.

Experience
Full Stack Developer
Rede Expressos 2023 - 2026
Three-year embedded engagement at Portugal’s largest intercity bus operator — the Web2 foundation that sharpens the systems thinking I bring to every protocol. Built a WebSocket-based telemetry pipeline with delta-compression for live fleet tracking, keeping the dashboard responsive under concurrent load while ingestion and broadcasting scaled independently. Delivered the operations management platform now handling approximately 70% of daily business across fleet, routing, pricing, and bookings.
