01
UI / UX
Product UI across web, POS, and Android — HeroUI, Tailwind, Material 3 / Compose, and 20-locale i18n including RTL. Interfaces that have to work in a mart, a chat at 3M users, and a super-app with 100k+ downloads.

Frontend
React, Next.js, Redux, React Native / Expo / Capacitor, Electron POS, and Jetpack Compose. Barcode checkout on the desktop, location-based grocery on mobile, and a social feed that still feels instant.

Backend
Node/Express and Bun/Elysia. JWT + store-level RBAC, Socket.IO with a Redis adapter, and AI pipelines — moderation, unique push, TTS, tool-calling agents. One API serving admin, POS, customer, and delivery.
