I’m a senior frontend engineer with 4+ years shipping production React (web + React Native) and Next.js applications across fintech, logistics, and AI domains. I build reliable user experiences and take full ownership—from architecture through deployment—on AWS, Azure, and Vercel.

I’ve led end-to-end delivery for complex, multi-interface products, including a subscription-based cab platform with three interfaces (React Native rider app, React/Next.js ops dashboard, fleet owner portal). I integrated Paystack recurring billing, supported reconciliation dashboards, and maintained 99.5% uptime while collaborating closely with backend engineers and stakeholders.

As a freelancer, I’ve delivered web and mobile frontends for 10+ clients across logistics, fintech, and e-commerce. I handle requirements gathering, implementation, third-party API integration, and deployment across AWS, Azure, and Vercel—working with distributed teams using async-first communication.

One of my standout projects is an AI interview platform (unbrain.io) serving 1,000+ active university students across 17 companies. I integrated AWS Bedrock, implemented prompt caching and an AI pre-detection chain to reduce unnecessary calls, and extended the experience with Sarvam AI TTS/STT—while building a secure admin panel, session monitoring, audit logs, and AI provider configuration.
