My role
I built the web platform and backend API solo for the client. The mobile apps (buyer app and Seller Center) were started by another developer; I took over their continued development and have been building out new features on both apps for over a year since.
Stack
Next.js with TypeScript and Tailwind on the web, Django REST Framework backed by PostgreSQL on the API, with the buyer and Seller Center mobile apps in Flutter.
