Summary
👤
Senior🎓
Top SchoolHiroto Shioi is a software engineer with a decade of experience building and hardening blockchain infrastructure, from support tooling to core node components. He began as a full-stack and Haskell developer at IOHK, where he translated the project whitepaper, taught peers during an intensive Haskell & Cryptocurrencies course in Barbados, and shipped a widely used log-classifier that helped resolve over 30,000 support tickets. He later joined a blockchain core team to design and implement the Cardano-shell and an accessible launcher that raised the project’s usability and security reputation. Now at Hashport, he continues to develop blockchain R&D projects including secure exchange wallets and NFT work, blending practical user-focused tools with low-level distributed-systems expertise. Based in Chiba, Japan, he pairs strong Haskell and systems experience with a knack for documentation and tooling that makes complex blockchain technology accessible to non-specialists.
