I'm Thelma, a product designer with 8 years of experience. I specialise in complex, regulated systems that help expert users move fast without breaking things.

I've shipped RBAC and multi-tenancy controls for air-gapped 5G infrastructure, ML trust UX for Apple's battery R&D, and financial tooling processing $9B+ across 4 African markets.

Outside my role at ChipperCashPan-African payments infrastructure — I led B2B API, merchant tooling, and onboarding optimisation UX processing $9B+ across 4 African markets., I'm building VerifySknAn AI-powered skincare authentication app — designed and coded by me, using Claude Code and a Next.js/Supabase stack. — independently taking a product from idea to working system across design, code, and architecture.
