Featured Work

Production applications I've architected and built, from schema-driven rendering platforms to fintech and on-demand delivery apps.

01 — Low-Code / Server-Driven UI Platform

FlexiDesigner

AKWA Group · Senior Mobile & Frontend Developer

Designed and built a platform-agnostic rendering engine that interprets JSON UI schemas and generates functional interfaces across React and React Native from a shared TypeScript core.

Defined a custom JSON schema-tree specification and TypeScript rendering engine, then integrated it with GrapesJS so non-technical users could visually design interfaces and instantly render them into production mobile and web UIs. Now powers 5 production applications — My Afriquia, iGaz, iLub, SAV SMDC, and AfriPOS.

Bun Coffee

Lead Mobile Developer / Product Engineer (Freelance)

Ordering app for the Bun coffee brand. Built the React Native application from the ground up and own the mobile lifecycle end-to-end — architecture, development, releases, and production support — including the core ordering and checkout experience, QR-code pickup, loyalty, and referral functionality.

Implemented device fingerprinting and Google Play Integrity API checks to detect and mitigate loyalty and referral abuse, and integrated Mixpanel, Sentry, OneSignal, and Firebase Analytics for product analytics, observability, and notification delivery.

On-demand home services marketplace — booking, service discovery, and real-time request tracking. Built the React Native app and the React.js/Next.js web platform from a shared design system, including account management, address management, and CMI / Kenz'up payment flows.

Engineering Highlights

A cross-section of the technical problems I own day to day, from architecture down to release engineering.

Architecture
Cross-platform architecture spanning React and React Native, server-driven UI, schema-driven rendering, and reusable component systems.
Performance
Profiling and optimization work that measurably improved load times and rendering — including a 60% reduction in app load times.
Security
Device fingerprinting, Google Play Integrity API checks, and secure payment flows including 3D Secure card tokenization.
Integrations
REST and GraphQL APIs, CMI and Kenz'up payment flows, Nexgo POS terminals, Google Places, push notifications, and enterprise (Odoo) backends.
Testing
Unit and integration testing with Jest, E2E automation with Detox and Maestro, and production validation before every release.
Delivery
App Store and Google Play release management, CI/CD pipelines, OTA updates, and production monitoring across client and internal applications.

AI-Enhanced Engineering

I use modern AI development tools to accelerate architecture exploration, implementation, debugging, testing, and documentation — while maintaining production engineering standards.

AI speeds up how fast I move from problem to solution. It doesn't replace engineering judgment: architecture decisions, code review, and production ownership stay with me.
