About Me
Freelance AI Product Developer · Rajshahi, Bangladesh · Remote worldwide
I build AI agent SaaS products, AI-powered mobile apps, and MVPs for founders and teams worldwide — working remotely from Rajshahi, Bangladesh (UTC+6) and owning every layer from architecture to launch.
“I believe great software should feel invisible — it just works, and the people using it never have to think twice.”
My journey into development started with curiosity — taking apart websites to understand how they worked, then rebuilding them better. That curiosity turned into a career spanning five years of building web applications for startups, agencies, and established businesses alike.
I specialize in AI agent SaaS, AI-powered mobile apps, and MVPs on a stack I know deeply — Next.js, NestJS, TypeScript, PostgreSQL, React Native and Expo, with OpenAI, Anthropic Claude, and retrieval pipelines behind the product. I care about the details that decide whether AI ships: evaluation sets, cost controls, clean APIs, and interfaces that respect the user’s time.
When I'm not coding, you'll find me exploring new technologies, contributing to open source, or writing about the lessons I've learned along the way. I believe in continuous growth — both in code and as a person.
The principles behind every project
Readable, maintainable, and well-tested. Code should communicate intent as clearly as prose.
Every interface decision starts with the person using it. Performance, accessibility, and clarity come first.
No jargon, no surprises. I keep clients informed with regular updates and honest timelines.
Technology evolves, and so do I. I invest in learning so every project benefits from the latest thinking.

Who I am, where I work from, and how to start a project
I'm a freelance AI product developer from Rajshahi, Bangladesh, working under the name Mursalin's Desk. I build AI agent SaaS products, AI-powered mobile apps with React Native and Expo, MVPs for startups, AI integrations for existing products, and full-stack web platforms on Next.js, NestJS and PostgreSQL. I also take on AI strategy and fractional CTO engagements for founders who need senior technical leadership without a full-time hire.
I'm based in Rajshahi, Bangladesh, and also work from Dhaka. Most of my clients are remote — startups and small companies in the US, UK, Canada, Australia and the EU. I can meet in person in Rajshahi or Dhaka when that helps, but every project I run is set up to work fully remotely from day one: shared repo, project board, async updates and scheduled calls.
Yes. You can hire me directly, without an agency or marketplace in between. We agree a scope and price, sign a contract with IP assignment and an NDA if you need one, and you pay by milestone through Wise, Payoneer or bank transfer. I have shipped production LLM agents, RAG systems and AI mobile apps for overseas clients this way, with code in your repository and infrastructure in your accounts.
I work in UTC+6 (Asia/Dhaka). That is 5 hours ahead of London and 10-11 hours ahead of New York, so I overlap with the full UK and EU afternoon and with US mornings and evenings. I keep a fixed daily window for calls, answer messages within a working day, and run the rest of the project asynchronously with written updates, so you never wait on my clock to make progress.
Book a free 30-minute call or send a short brief through the contact form. On the call I ask about the problem, users, budget and deadline, and tell you honestly whether one of my packages fits or a custom scope is better. Within two working days you get a written proposal with scope, milestones, price and timeline. Once you approve it and pay the first milestone, work starts the following week.
I invoice in USD and accept Wise, Payoneer and international bank transfer; Stripe invoicing is available for card payments. Fixed-price packages are split into milestones: typically 40% to start, 40% at the mid-point demo, and 20% on handoff. Hourly work is tracked and invoiced weekly, and retainers are billed at the start of each month. You always receive a proper invoice you can expense.
