I build production-grade Flutter applications for fintech, social commerce, healthcare, and edtech — and I publish the tooling I wish had existed when I started. Based in Port Harcourt, Nigeria. Open to remote opportunities worldwide.
- OfflinePay Nigeria — engineering a cryptographic offline P2P payment system for the Nigerian market, using Ed25519 signing, AES-256-GCM QR/NFC transport, and a Serverpod (Dart) backend. Built to work where internet access doesn't.
- Merkado Flutter SDK — a shared Flutter SDK powering 5 live consumer apps with unified payments, KYC, identity, wallet, and design system infrastructure.
- Contributing to the Solana/Web3 ecosystem as a builder and former Tech Lead of the Superteam Nigeria Port Harcourt chapter.

Beyond the code, I find deep inspiration in space exploration — and I believe the same curiosity that sends probes to the edge of the solar system is what makes great engineers push past the obvious solution.
