What I Cover

Full Next.js stack — frontend to deployment

One developer who owns the entire delivery. No handoffs between frontend, backend, and DevOps.

Server components, streaming, route handlers, middleware, and client/server boundary architecture.

Full-stack delivery

Frontend, backend API routes, database layer, auth, and Vercel deployment — owned end to end.

MongoDB + PostgreSQL

Mongoose for document data, Prisma for relational. Schema design, indexing, and query optimization.

Auth (NextAuth / OAuth)

Google, GitHub OAuth and email login with JWT sessions, refresh tokens, and protected routes.

Stripe integration

One-time checkout, subscriptions, feature gating, Customer Portal, and Stripe Connect B2B.

Vercel deployment

FAQ

Common questions

Do you work as a freelancer or an agency?

PolarSoftBD is a small specialist team — not a large agency with account managers. You communicate directly with the developer building your product. Think of it as hiring a senior engineer with full-stack delivery ownership.

Can you work on my existing Next.js codebase?

Yes. I work with existing codebases — adding features, fixing architecture issues, integrating Stripe, adding auth, or building new sections. I review the code before quoting to account for any complexity.

What Next.js version do you work with?

Primarily Next.js 14 and 15 with the App Router. I can also maintain older Pages Router projects, but all new builds use App Router with React Server Components.

Do you use TypeScript?

Always. Every project I deliver is fully typed — components, API routes, database models, and shared types. No any. No implicit returns. TypeScript is non-negotiable for production code.

Can you deliver to a tight deadline?

Depends on scope. Simple integrations (Stripe checkout, auth setup) take 1–5 days. Full apps take 2–8 weeks. Scope the project first — I'll give you an honest timeline, not a sales answer.

Do you work with clients outside Bangladesh?

Yes — US, UK, Canada, Australia, and Europe. All communication in English. I align to your timezone for calls and deliver via GitHub or your preferred method.
