What I'm looking for

I'm looking to build scalable, AI-powered web applications and secure backend systems, with opportunities to apply clean architecture, cloud technologies, responsive design, accessibility, and reliable payment integrations.

I build and deploy full-stack web applications that pair modular React frontends with secure Supabase and PostgreSQL backends.

For SabiWrite AI, I designed an end-to-end AI writing platform using React 19, Deno Edge Functions, Supabase, PostgreSQL, and the Gemini API. I built 12 database migrations, automated quiz generation, mistake analytics, gamified skill tracking, and role-based authentication.

With ChurchDue, I created a contribution ledger and dues-tracking platform with Row Level Security. I also developed serverless functions for Paystack checkout, transaction verification, and real-time webhook processing.

I focus on scalable, maintainable software through clean architecture, responsive interfaces, secure API patterns, multi-tenant data isolation, and WCAG AA accessibility standards.
