Full-stack developer Chittagong, Bangladesh

Muhammad Junaidbuilds whole products, from the database to the home screen.

I work in React Native, Next.js, Node.js and TypeScript. Since 2021 I’ve shipped mobile apps, web platforms and the APIs behind them for teams in Bangladesh and the US — twice as the lead React Native developer.

Selected work

One product in depth, then the rest at a glance. Every project opens a write-up with the stack, the hard parts and links to the live product where it’s public.

Featured case study Full Stack

AI Bee is a full-stack SaaS that puts one AI agent behind every Meta conversation a business has. It connects Facebook Pages, Messenger, Instagram and WhatsApp (plus Telegram and a website chat widget) into one unified inbox, answers customer DMs and comments 24/7 in the customer's own language, qualifies leads, books meetings and hands off to a human when needed.

The hard parts

  1. 01Replies that stay grounded in the business's own facts
  2. 02Never promising what the team won't deliver
  3. 03Webhooks at real-world volume
  4. 04Handing a conversation between AI and humans cleanly
