About

I’m a full-stack web and mobile engineer focused on building secure, scalable products for startups and businesses.

I work mainly with Python and Django on the backend, and Next.js, React Native and Expo for web and mobile experiences.

I’ve built and shipped production systems including ticketing platforms with payment integrations, e-commerce platforms, referral-based applications, marketing websites, financial applications and AI-powered applications.

What matters most to me is clean architecture, getting things done efficiently, and building products that solve real problems.

What I help with

01 Django & Django REST Framework applications
02 REST APIs and backend architecture
03 Authentication & user management
04 Payment integrations (Paystack, Flutterwave)
05 Next.js web applications
06 React Native & Expo mobile applications
07 MVP development for startups
08 Third-party API integrations

Also comfortable with Paystack and Flutterwave integrations, Celery, Docker, and shipping to Vercel, Railway and Expo EAS.
