Senior🎓
Top SchoolAlexander Doo is a Blockchain Smart Contract Engineer with a decade of software experience, combining a strong computer science foundation from Stony Brook University with hands-on expertise in Solidity, TypeScript, Python, Go, and cloud platforms. He has built end-to-end blockchain products—NFT marketplaces supporting ERC721/1155/2981, oracles, and dApps—often owning smart contracts, backend services, frontends, and AWS dev-ops. Comfortable across the full stack, he leverages traditional strengths in Java, MVC design, and TDD while exploring Haskell and Rust for Cardano and Solana experiments. At startups like Zap Protocol, M9 Solutions, and Tassat he’s shipped production-grade systems that connect real-world data to chains and streamline IP/asset flows. Outside work he’s an avid hiker and kayaker, bringing the same relish for difficult challenges and long routes to solving complex engineering problems.
