I build fintech and Web3 systems for payments and on-chain verification.
NigeriaWhat I'm looking for
I've built production fintech and Web3 systems at BLIA, Tradable, and Tecmie, spanning banking integrations, real-money movement, smart contracts, and on-chain verification.
At BLIA, I independently took an on-chain payment and attestation system for a real estate escrow platform from design to production in six months. I integrated Cybrid for USD-to-USDC conversion and identity workflows, MeCash for off-ramping, and Ethereum Attestation Service for escrow-milestone verification.
At Tradable, I built a multichain decentralized trading platform that reached $36K in TVL, including smart contracts, cross-chain messaging, automated execution, a matching engine, order book, and release frontend.
I also build experimental protocols, including a privacy-preserving transaction system using zk-SNARKs, an EVM mempool listener, NFT swaps, and token-launch mechanics. I co-authored Yul By Example and enjoy owning systems end-to-end, from AWS and Terraform through application logic.
