Full-stack engineer at Tunnl who built creator dashboards and USDC payout flows sending $900K+ to creators.

Nigeria

Message

At Tunnl, I built the creator marketing platform’s admin dashboard and API, bringing management of users, campaigns, and submissions into one place. I also integrated USDC escrow payouts that sent $900K+ to creators.

For Mimix, Tunnl’s successor platform, I architected the admin dashboard and much of its API. I delivered a review and payout flow across four social platforms and two chains, and designed role-based access for brands and agencies.

I co-founded KampusPlug, a campus marketplace for Nigerian students and vendors, and wrote about 90% of its codebase. I redesigned checkout around escrow payments and implemented wallets using Squad virtual accounts.

Across backend roles at Vobb, RahaPay, and Atoovis, I built email, payment, and order-management systems. My work included improving API response times, automating inbox sync, and reducing failed deliveries through address validation.
