Rockstar🎓
Top SchoolSammy Harris is a Senior Protocol Engineer specializing in mobile and blockchain systems with seven years of full-stack experience spanning Rust to React. Currently at Solana Labs and contributing to Anchor v2 for the Solana Foundation, Sammy blends low-level smart contract work with front-end UX improvements, having shipped features in high-profile projects like Metaplex and the Anchor framework. Their contributions span on-chain program logic (Candy Machine collections, freezes, whitelist mechanics) to developer tooling and docs, plus UI/UX work such as HTML asset support and Algolia docsearch integration. Comfortable across backend protocol safety checks and frontend TypeScript/React, they have a track record of shipping robust, production-ready changes in open-source ecosystems. Based in Chicago and educated in computer science and software engineering at Rose‑Hulman, Sammy brings both protocol-level rigor and product sensibility to blockchain developer experiences. An understated strength is their ability to move between developer relations, architecture, and hands-on implementation—making complex blockchain primitives accessible to app developers.
