I build full-stack fintech and payment platforms with Node.js, React, and multi-chain stablecoin integrations.
NigeriaWhat I'm looking for
I've built payment products at Monirates, including a multi-chain USDT and USDC feature across Solana, Base, and Ethereum, plus backend services for cross-border payment flows from initiation to settlement.
I work end-to-end with Node.js, TypeScript, Express.js, PostgreSQL, MongoDB, React.js, Next.js, and React Native. I build secure REST APIs, authentication and authorization flows, responsive transaction interfaces, and mobile financial experiences.
At Singularity Core, I shipped campaign-management and analytics dashboards for out-of-home advertising, owned backend delivery for a period, and built APIs, data models, payments, reporting, and role-based access for agencies and brands.
