I'm leading the frontend rebuild at Expert Listing, a Nigerian real estate platform, delivering its social feed, real-time messaging, account onboarding, and video pipeline in Next.js and TypeScript.

I built conversations, read receipts, unread counts, phone OTP verification, Google OAuth, and HLS video playback, while hardening the product for iOS Safari and constrained networks.

At Dezenmart, I'm the founding frontend engineer for a live Celo-based e-commerce and payments platform. I own architecture, state management, reusable components, and Celo payment flows with escrow; the product placed fourth globally in Proof of Ship Season 5.

I've also delivered full-stack React and Node.js features at Kommas500 and accessible React interfaces at Prunedge. I care about clean integration patterns, testing, code review, and helping contributors work effectively in evolving codebases.
