Freelance Next.js Developer in Bangladesh

Most of my Next.js work is SaaS: multi-tenant products with team workspaces, role-based access, Stripe subscriptions and webhooks, admin dashboards and a marketing site that ranks. I also build content-heavy sites where SEO and Core Web Vitals matter, and AI products where streaming responses, server actions and background jobs have to work together.

Founders — a reputation platform for startup founders — runs on Next.js 16, React 19 and a NestJS API. MedScribe is a prescription platform for doctors on Next.js and PostgreSQL. HennaHub is a full-stack e-commerce and booking platform on Next.js 16 with Hono on Cloudflare Workers. Contently AI is a multi-model content SaaS on Next.js with OpenAI, Anthropic and Groq behind it.

Rendering: server components by default, client components only where there is interaction, and static or incrementally regenerated pages wherever the data allows. This keeps the JavaScript bundle small and the pages fast on the phones most users actually have.

Backend: for a small product I keep the API inside Next.js route handlers and use Supabase for Postgres, auth and storage. When the product needs webhooks, queues, a mobile client or business logic that several clients share, I add a NestJS service with Prisma, BullMQ and Redis. Both are TypeScript end to end, so the types stay shared.

Data and deployment: PostgreSQL always, on Neon or Supabase for early products and on a managed instance later. Vercel for the Next.js app; Render, Fly or a container platform for NestJS; Docker for anything that must run in a client's own cloud. Every project ships with CI, automated tests and monitoring.

A fast, SEO-ready marketing site or landing page is $499 and takes one to two weeks. A production web application on Next.js and NestJS with auth, roles, PostgreSQL, Stripe billing, an admin dashboard and CI/CD is $2,499 over four to six weeks. A scalable platform with multi-tenancy, realtime features, Redis, queues and full observability is $7,999 over eight to fourteen weeks.

Hourly work — joining an existing Next.js codebase, performance or SEO fixes, an upgrade to a new Next.js version — is $100-150 an hour, tracked weekly. A monthly retainer with reserved hours starts at $500. For reference, typical Bangladesh outsourcing rates are $15-35 an hour for mid-level work and US Next.js contractors bill $120-200; I sit in between with senior product experience.

Hiring directly instead of through Upwork or Toptal means no platform fees, a contract in your name, and a developer who is not optimising for a rating. My standard agreement covers scope, milestones, confidentiality and full IP assignment on payment. Invoices are in USD and payable by Wise, Payoneer or bank transfer. Code goes into your GitHub organisation from the first commit and deployments run in your accounts.

I work in UTC+6 with a fixed call window that overlaps the UK and EU afternoon and US mornings and evenings. Between calls the project runs asynchronously on a shared board with written weekly updates. If you want to test the fit first, a paid one-week engagement — a code audit, a performance sprint, a small feature — is the usual way to start.
