What I'm looking for

I'm seeking internships.

At Joygiver, I took products from first prototype to live, paying products, including a group-gifting app with a React Native app, Next.js pages, and a Django API. I integrated Paystack contributions, identity verification, OTP sign-in, and live contribution totals.

For BigPlug, I built reseller, vendor, and agent apps alongside a customer storefront on a shared Django backend. I designed the escrow ledger and order state machine, and automated vendor payouts through Paystack.

At AllSermon, I built a React Native app and Django/Celery backend, including an asynchronous transcription pipeline and semantic search that helps users find sermons by meaning.

At BuildBusters, I built the platform infrastructure and product flows, including Stripe milestone payments, real-time client messaging, and an end-to-end Playwright test suite. I’ve also worked on AI features for client products, including assistants, speech-to-text pipelines, and semantic search.
