Leadership & Experience
Proven track record architecting robust mobile systems, enterprise platforms, and high-performance fintech solutions.
Led mobile architecture for Flexr, an Earned Wage Access (EWA) platform allowing employees to seamlessly access earned salaries before payday.
Key Highlights & Deliverables
- Architected offline-first transaction queues using SQLite and client-generated UUID idempotency keys, eliminating duplicate salary advance payouts during dropped connections.
- Built a robust background sync engine that safely buffers payroll adjustments and loan originations, retrying them exponentially to ensure 100% HR ledger consistency.
- Integrated robust biometric authentication (FaceID/TouchID) and zero-trust certificate pinning to secure ₦160M+ in sensitive financial disbursements from MITM tampering.
- Deployed real-time Sentry telemetry and custom structured logging to trace and patch race conditions in the payment pipeline before impacting users.

Engineered core mobile NFC and tap-to-share systems for Rope Africa, a smartphone-based digital identity and networking platform.
Key Highlights & Deliverables
- Engineered custom native Android (Kotlin) platform channels for low-level NDEF beaming and phone-to-phone NFC communication across fragmented OEM chipsets.
- Architected an automated BLE peripheral advertising and dynamic QR fallback protocol for recipient phones without active NFC, ensuring zero dropped contacts.
- Optimized the cold-start render pipeline of the receiver digital identity PWA, reducing Time-to-Interactive (TTI) to under 800ms through Edge CDN caching.
- Built real-time WebSocket state synchronization pushing instant credential updates and team profile edits directly across users' smartphones.
