Looking for a freelance Next.js developer?
I'm Sunil — a full-stack developer with 8+ years of experience and a 100% Job Success Score across 100+ clients on Upwork. I build production Next.js applications end to end: the front end, the API, the database and the deploy pipeline.
Most people who land here have one of two problems. Either they have a React app that's slow, hard to deploy and invisible to Google, or they have a product idea and need someone who can take it from empty repository to live URL without a team. Both are the job.

What you can hire me for
- Full product builds — from scoping through to a live, monitored deploy
- Next.js App Router migrations from Pages Router or Create React App
- Performance and Core Web Vitals work with before-and-after field data
- Headless CMS and eCommerce integrations (Shopify, Sanity, WordPress)
- API design in Node.js, NestJS or route handlers, with Postgres or MongoDB
- Ongoing retained development after launch

Why work with me on next.js
Fast without a performance project
Server components, image optimisation and self-hosted fonts come as defaults, not as a retrofit after launch. Core Web Vitals are part of the build, not a separate invoice.
Actually indexable
Server rendering means search engines and AI crawlers see your content, not an empty div waiting on JavaScript. That matters more every year.
One codebase, front to back
Route handlers and server actions mean the API lives beside the UI. Fewer moving parts, fewer deploys, and far less to explain when you hand it over.
It's still React
Your existing components, your existing hires, your existing ecosystem. Next.js is a framework around React, not a replacement for it — nothing you already know is wasted.
Deploys anywhere
Vercel if you want zero-config, or your own infrastructure if procurement says so. I've shipped both and I'll tell you honestly which one your project needs.
Built to be handed over
Typed, documented, conventional. The goal is a codebase your next developer can pick up in an afternoon — including if that developer isn't me.
What I build
SaaS products
Auth, billing, dashboards, multi-tenancy and an admin side that support can actually use. Starvio is one of these, live with paid plans.
Marketing sites that rank
Fast, structured, schema-marked pages built for organic traffic — the same approach this site uses.
Rescues and migrations
Create React App, Pages Router or a slow legacy front end moved to the App Router without a big-bang rewrite.
AI-backed features
Streaming responses, structured output and sensible failure states, wired into a Next.js app rather than bolted on.
Shipped, not theoretical
“Sunil has strong skills in IONIC Development and I like his sincerity and smart work skills. I strongly recommend him and will hire him for sure for next tasks or projects.”
“Sunil is a very good developer. He finished projects successfully and incorporated the feed back provided. I would certainly come back to him with more work for him in future.”
How the work runs
Discovery
Understand your goals, users, and what success actually looks like.
Strategy
Scope, architecture and a plan that fits your timeline and budget.
Design
Wireframes to polished UI — validated before a line of code ships.
Build
Fast, tested, well-documented development in weekly increments.
Ship
Deploy, monitor, and hand off a product your team can run.
Questions people ask first
How much does a Next.js project cost?
It depends on scope, and any number quoted before scoping is a guess. I run a short paid discovery that produces a screen-by-screen plan you own, then quote fixed price for the known work and time-and-materials with a cap for genuine unknowns like legacy migrations.
How long does a build take?
Small marketing sites are typically 1–2 weeks. Full products run 4–8 weeks depending on scope. You get a deployed link and a written update every week, so nothing is a surprise at the end.
Do you work with existing teams?
Yes. A lot of my work is joining an in-house team as the senior front-end or full-stack pair for a defined stretch — code review, architecture and shipping features alongside your developers.
What timezone do you work in?
I'm based in India and work with clients worldwide, with overlap hours agreed up front. Most of my clients are in the US, Canada, UK and the Gulf, and async updates mean the timezone rarely becomes the bottleneck.
Who owns the code?
You do, in full, from day one. Work happens in your repository where possible, and the handover includes documentation and a walkthrough.
Tell me what you're building
Send over the scope — or the rough idea — and I'll come back with an honest read on approach, timeline and cost. No obligation, and no sales sequence.
