Senior Frontend Engineer with 7 years of production React, Next.js and TypeScript. I currently lead frontend for MonieWorld at Moniepoint, a cross-border payments product serving 50,000+ users in the UK, Nigeria and Kenya. I cut dashboard load time from 2.8s to 1.4s, took end-to-end test coverage on payment flows from 35% to 85%, and built a shared component library adopted by 4 teams. Before that I spent two years on Web3 frontends at early-stage startups (Unlockd, myNFT): wallet flows, on-chain transaction states, Ethers.js, Viem and The Graph. I use Cursor and Claude Code daily. Open to remote roles with US and EU teams.
