Hire one developer for the whole job: working out what to build, building it, and putting it live. Remote, for clients anywhere — based in Dhaka (UTC+6) and writing code since 2018.
AI assistants that answer your customers and take routine work off your team, on your website, WhatsApp or Telegram.
An agent that works from your own information and does the routine part of the job: answering questions, collecting the details and passing the rest to a person. Anything that matters waits for someone on your team to approve it — the same rule Clearday's assistant follows before it touches a user's calendar.

OpenAI, Claude and Gemini wired into a real product, each on the part of the job it does best.
Not a chat box bolted on: the model does one job inside the product, and the app is built around it. It is how SplitMate reads a receipt, how ProAI Training scores a spoken roleplay and how Clearday writes its morning brief. ProAI Training runs OpenAI, Gemini and Claude side by side, each where it is strongest, with ElevenLabs for the voices.

Bots that meet customers where they already message, on the official WhatsApp Business API and Telegram Bot API.
Answering common questions, sending updates and taking simple requests in the chat app your customers already use. Connect one to an AI agent and it can hold a real conversation, with a hand-off to a person when it should.

iOS and Android apps from one codebase, in React Native or Flutter, with the backend behind them.
From the first screen to a release on both app stores. SplitMate works offline and syncs when the signal comes back; FeedSeek and Clearday each pair the phone app with an API built for it.

Web apps with Next.js and React on the front and Node.js behind them.
Accounts, dashboards, admin screens and the data model under them, built and deployed by the same person, so nothing gets lost between the front end and the back end. This site is a Next.js build.

Shopify apps merchants install from their admin: storefront flows, admin screens and rules they change without code.
FrameRx is the most recent: it lets any eyewear store sell prescription lenses, with a guided lens flow on the product page, a verification queue for the merchant and a no-code rule builder behind both. Two earlier Shopify apps are public on GitHub.

REST APIs with Node.js: accounts, auth, sync and the jobs a phone should not do.
The server side behind an app: the data, the accounts and the work that has to happen even when the app is closed. FeedSeek's backend runs accounts, listings, reservations and an admin console; Clearday's runs sync and the AI layer.
The smallest version that is actually useful, released in pieces instead of saved for one big reveal.
You see working screens early, while changes still cost hours instead of weeks. Every project on this site — product, app and site — was built solo, end to end.

Fast sites that explain one product well.
splitmate.live, the landing page for SplitMate, is plain HTML, CSS and JavaScript with no framework and no build step, so it loads fast and stays easy to edit. This site is the Next.js version of the same idea.

What you are building, what already exists, and when you need it working.
I start with the smallest version that is actually useful, then release in pieces rather than saving everything for one big reveal.
You get a link you can click early on, while changes still cost hours instead of weeks.
If something is not ready, you hear it from me first, with what is blocking it and what I am doing next.
Yes. 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.
Dhaka, UTC+6. Every message reaches me directly, and I answer it myself.
Yes. FeedSeek and Clearday each have a phone app and a backend I built, and SplitMate has the app and its marketing site. Every project on this site was built solo, end to end.
Yes: an assistant that answers your customers and handles routine work, on your website, WhatsApp or Telegram, using OpenAI, Claude or Gemini. Anything that matters waits for a person on your team to approve it.
Yes. FrameRx, a prescription-lens app for eyewear stores, is the most recent, and two earlier Shopify apps are public on GitHub.
Send a short brief: what you are building, what already exists and when you need it working. WhatsApp reaches me fastest; email or the contact form work too.
