Hire a remote developer who builds the whole thing
I am Rokibul Hasan, a freelance full stack and app developer in Dhaka, Bangladesh, working remotely for clients anywhere. One person plans, builds and launches your project: the web app, the mobile app, the backend behind them, Shopify apps and AI agents.
You talk to the person writing the code, get a fixed quote before work starts, and own everything at the end.
Why hire one developer instead of a team
One person, start to finish
No hand-offs between a designer, a front-end team and a back-end team. The person who works out what to build is the person who builds it and puts it live.
Direct answers
Every message reaches me directly, and I answer it myself. If something is not ready, you hear it from me first, with what is blocking it and what I am doing next.
Working screens early
You get a link you can click early on, while changes still cost hours instead of weeks.
Yours at the end
You own the code, the accounts are in your name, and handover notes mean the next developer can pick it up without a rewrite.
How working together remotely works
Everything runs remotely, so where you are does not matter: the brief, the updates and an early link you can click all travel over WhatsApp and email.

What you can hire me for
- AI agents for business AI assistants that answer your customers and take routine work off your team, on your website, WhatsApp or Telegram.
- AI API integration OpenAI, Claude and Gemini wired into a real product, each on the part of the job it does best.
- WhatsApp & Telegram bots Bots that meet customers where they already message, on the official WhatsApp Business API and Telegram Bot API.
- Mobile app development iOS and Android apps from one codebase, in React Native or Flutter, with the backend behind them.
- Full-stack web development Web apps with Next.js and React on the front and Node.js behind them.
- Shopify app development Shopify apps merchants install from their admin: storefront flows, admin screens and rules they change without code.
- API & backend development REST APIs with Node.js: accounts, auth, sync and the jobs a phone should not do.
- MVP & product builds The smallest version that is actually useful, released in pieces instead of saved for one big reveal.
- Shopify store automation The repetitive work in a Shopify store done by software: products, prices, stock and orders.
- Amazon Seller Central & PPC automation Listings, inventory, orders and reports in Seller Central automated, and Amazon ads adjusted by rules instead of by hand.
- Marketplace integrations Amazon and Etsy connected in either direction, and Shopify connected to TikTok Shop, so products, stock and orders stay in sync.
- Landing pages & marketing sites Fast sites that explain one product well.
What I have shipped
Writing code since 2018, with 62+ projects completed. These five products were each built solo, end to end:
- FrameRx
A Shopify app that lets any eyewear store sell prescription lenses: a guided lens flow on the storefront, a verification queue for the merchant, and a no-code rule builder behind both.
- ProAI Training
Rehearse the conversations you cannot redo: a spoken roleplay against an AI character who argues back, then a scored report on how you handled it.
- Clearday
An AI life organizer: tasks, calendar, habits, trackers and goals on one surface, with a brief each morning, a recap each night and suggestions you approve before they land.
- SplitMate
A free travel app for groups: live expense splitting in 150+ currencies, AI receipt capture and a Face ID document vault, all working offline.
- FeedSeek
Surplus food shared before it hits the bin: neighbours list what they have with a pickup window, and it gets reserved and collected with a code.
