I’m Cyubahiro Emmy, a Smart Contract Engineer and Web3 developer focused on building privacy-first, security-first decentralized products for agriculture, payments, and digital identity across East Africa. I ship end-to-end systems—writing Solidity smart contracts, designing on-chain access control and escrow flows, and pairing them with backends, indexing, and user-friendly interfaces. I’ve built and launched AeternaVault and AgriHash, and I’ve also worked on ZK-enabled cross-border settlement concepts for East African payments and a digital driver/vehicle identity verification platform. I enjoy combining practical product engineering with smart security practices (including audits and OpenZeppelin upgrades) to make on-chain functionality useful, provable, and safe for real users.…I’m Cyubahiro Emmy, a Smart Contract Engineer and Web3 developer focused on building privacy-first, security-first decentralized products for agriculture, payments, and digital identity across East Africa.
