Freelance build — the whole frontend of an eSIM data service, still in production.

A freelance engagement, June to December 2022, on Sparks eSIM — a digital SIM service selling mobile data plans to travellers across 40+ countries.
I wrote the entire frontend and its architecture and took it through to production. The product still runs on that code, and the companion React Native application was derived from the same React codebase.
The Android app is on Google Play.
