I build scalable fintech, crypto, and mobile products with TypeScript, Node.js, React, and distributed systems.
NigeriaWhat I'm looking for
At Technova Technologies, I architect type-safe gRPC communication across Accounts, POS, and Business microservices, and built dual-debit accounting for agency banking transfers and fees.
I’ve delivered products across fintech, crypto, ecommerce, and Web3, including the SmartX crypto exchange mobile app, the Spacebank web app, Saveply, Pennystack, and Tsunami Ecommerce. My work spans React Native, Next.js, Node.js, real-time APIs, state management, and high-volume transaction workflows.
I also lead delivery and technical strategy, introducing sprint workflows that improved team velocity by 25% and helping global clients reduce production bugs through TypeScript-focused MERN solutions.
