Full Stack Developer for Nextjs, NestJS and React Native apps
Bangladesh
Inglese, Hindi, Bengali
Chi sono
I build and maintain web and mobile apps: Next.js front ends, NestJS APIs on PostgreSQL, and React Native apps with Expo. Three years of production work and 17 products shipped, including a wholesale ERP, a multi-tenant retail POS, a comic shop storefront with Stripe and PayPal, and five apps taken through App Store and Play review. Typical jobs: finishing or fixing an existing codebase, speeding up a slow site, adding payments, publishing an app. I reply the same day and send a short written summary with every delivery.
