Freelance MVP Developer in Bangladesh — Idea to Launch in 4-6 Weeks

My MVP packages are fixed price and published. Starter is $999 and takes two to three weeks: a scoping workshop, one core user workflow end to end, up to six screens, auth, a PostgreSQL database and a live URL on a custom domain. Professional is $2,999 over four to six weeks: up to fifteen screens, Stripe payments or subscriptions, one AI-powered feature, onboarding emails, an admin dashboard, analytics and an SEO-ready landing page. Enterprise is $7,499 over eight to twelve weeks for a pilot-grade product with SSO, roles, audit logs and integrations.

For comparison, local agencies in Bangladesh typically quote $6,000-10,000 for a lean MVP, and US or UK studios start around $25,000 and run to $40,000 for something simple. The difference is not lower quality; it is one senior engineer in Rajshahi instead of a project manager, a designer, two developers and an office in San Francisco.

Week one is a scoping workshop and user-story mapping. We write down the single workflow a user must complete for the idea to be validated, list what is explicitly out of scope, and agree the milestones. I then set up the repository, the database schema, auth and deployment so that there is a live URL by the end of the first week, even if it only shows a login page.

Weeks two to four are the core build with a demo every Friday. Payments, the AI feature and the admin view come in the order that de-risks your launch. The final week is polish, onboarding emails, analytics, error tracking and a launch checklist. Every package ends with a handoff: your GitHub organisation holds the code, your accounts hold the infrastructure, and you receive documentation and a walkthrough call.

Next.js with the App Router for the product and marketing pages, NestJS for the API when the product needs webhooks, background jobs or a mobile client, PostgreSQL through Prisma, and Vercel plus a managed Postgres like Neon or Supabase for hosting. This stack is boring in the best way: cheap to run, easy for any future hire to pick up, and it scales far past MVP traffic without a rewrite.

For very small products I will keep the API inside Next.js route handlers to save money and complexity. For products that are AI-first I add the OpenAI or Anthropic Claude APIs with cost caps and an evaluation set from the first week, because an AI feature that behaves unpredictably is worse than no AI feature in a demo to investors.

Founders is a reputation and community platform for startup founders built on Next.js 16, NestJS and PostgreSQL. MedScribe is a prescription platform for doctors that started as a focused MVP and grew into a clinical tool. Contently AI is a multi-model social content SaaS with OpenAI, Anthropic and Groq behind a single interface. Each one started with a single workflow and a fixed budget, which is how I would start yours.

I work in UTC+6, which overlaps the UK and EU afternoon and both ends of the US day. You get a fixed weekly call in that overlap, written updates every week, and a shared project board where every decision is recorded. Payment is by milestone in USD via Wise, Payoneer or bank transfer, typically 40% to start, 40% at the mid-point demo and 20% at handoff, and I sign an NDA before seeing anything sensitive.

If you are not sure whether your idea fits a package, book a free 30-minute call. I will tell you which tier fits, what I would cut, and what it will cost to run once it is live.
