About
My philosophy is simple: engineering is a means to an end, and that end is product-market fit and revenue. I build high-performance frontend architectures, mobile experiences (Flutter/Dart & native systems), and developer tooling that directly serve those goals.
I specialize in bridging the gap between product design and resilient architecture. Whether it's taking a raw idea from 0-to-1 or untangling massive technical debt for a scaling startup, I focus on mechanical sympathy: zero dropped frames, fluid gesture response, offline reliability, and clean state management.
Currently, I am looking for opportunities to architect cross-platform systems where speed of execution, extreme product craftsmanship, and real-world business impact are the primary metrics for success.

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.
Scaled a high-performance diaspora e-commerce and logistics platform, optimizing heavy data pipelines and real-time order state.
Key Highlights & Deliverables
- Offloaded multi-megabyte JSON catalog deserialization and heavy data parsing to background Dart Isolates, completely eliminating main-thread blocking and sustaining a flawless 120 FPS UI.
- Conducted deep memory profiling using Dart DevTools, diagnosing and patching unclosed LocationStream subscriptions that reduced driver app OOM crashes by over 20%.
- Architected a reactive GetX state management layer with aggressive debounce mechanisms, preventing rapid API thrashing during high-traffic flash sale checkout flows.
- Engineered a real-time driver dispatch state machine using Firebase Cloud Messaging, ensuring sub-second sync between customers, merchants, and logistics fleets.
Integrated autonomous AI agents and intelligent workflow automations into enterprise systems for CMND.ai.
Key Highlights & Deliverables
- Architected an autonomous LLM support pipeline using Express.js and advanced function calling, successfully resolving 75% of ~100 daily inquiries without human intervention.
- Built a highly concurrent webhook ingestion engine capable of parallelizing incoming conversational events, bridging them directly into legacy enterprise CRM systems for live scheduling.
- Hardened LLM prompt injection defenses and implemented strict output validation schemas (Zod), guaranteeing that AI-generated responses strictly adhered to business logic and brand tone.
- Contributed to the open-source Xest JavaScript framework core, diagnosing and resolving complex Windows OS path resolution and cross-platform process spawning bugs.
