$15K–$100K typical projects
Direct answer
Next.js development with me runs $15K–$100K — the low end covers a fast, SEO-sound marketing site or focused web app, the high end a full product dashboard or a careful migration of an existing codebase. I bring 7+ years of production delivery, have built apps used by millions of users, and am Top Rated on Upwork with $100K+ earned and verified client reviews. You work directly with the engineer writing the code, and every engagement is scoped route by route so the quote reflects your actual site, not a template price.
Next.js is the default choice for serious web products, but most Next.js projects underuse it — client-rendering everything, ignoring caching, shipping megabytes of JavaScript to render a headline. This service delivers Next.js the way it is meant to work: rendering strategy chosen per route, Core Web Vitals treated as a requirement, and a codebase your future team can extend.
You need an MVP or v2 shipped on budget with someone who makes architecture decisions and owns delivery end-to-end.
You need a senior IC to augment the team, rescue a codebase, or lead mobile + AI integration without months of hiring.
You need a reliable senior subcontractor for client projects — clear communication, store-ready quality, white-label friendly.
30 minutes — goals, stack, timeline, budget range.
Fixed milestones, clear deliverables, start date.
Weekly demos, async Slack updates, production standards.
Store launch, documentation, knowledge transfer.
Your site is slow, your Core Web Vitals are hurting rankings, and publishing content requires a developer. I rebuild it on Next.js with static generation, a CMS your marketing team can drive, and structured data baked in. The outcome is a site that scores well on the metrics search engines actually measure — and a publishing workflow that no longer bottlenecks on engineering.
Your SaaS needs a real web application: authentication, role-based views, data-heavy screens that stay responsive. I build it with the App Router — server components for data-heavy reads, client interactivity only where it earns its bundle weight — plus proper loading and error states throughout. You get an app that feels instant and a codebase organized around your product's actual domains.
You are on Create React App, an aging Pages Router build, or a framework the team wants off, and a big-bang rewrite feels too risky. I run the migration incrementally — route by route, with redirects, analytics continuity, and SEO preserved — so the business never notices the transition except in the performance graphs. The old stack retires without a traffic cliff.
Every route in a Next.js application has a choice: static generation, incremental regeneration, server rendering, or client rendering — and each choice has a business consequence. Marketing pages and content want static generation because speed converts and search engines reward it. Dashboards want server components with streaming so users see data fast without shipping a mountain of JavaScript. Truly interactive surfaces earn client rendering.
Most underperforming Next.js sites I audit made no choice at all: everything renders one way because that was the default when the project started. I make the choice explicit per route during scoping, tied to what the route is for — conversion, retention, or search traffic. That single discipline is responsible for more of the performance and SEO outcome than any clever optimization applied later.
A marketing site with a CMS, a handful of templates, and strong Core Web Vitals sits at the low end. The budget grows with application complexity: authentication and roles, data-heavy dashboard screens, third-party integrations, internationalization, and design systems built from scratch rather than adapted. Migrations are priced by surface area — how many routes, how much custom tooling or legacy state management must be untangled, and how strict the no-regression requirements are.
Two cost drivers surprise buyers. Design maturity is one: pixel-perfect implementation of a polished design system is fast, while figuring out design as we go quietly doubles frontend time. Editorial workflow is the other: marketing edits everything without a developer is a real feature with real scope, not a checkbox. I surface both in the first scoping conversation so the quote holds.
Week one produces a deployed skeleton on your infrastructure — routing, layouts, CI, preview deployments wired to pull requests — so every subsequent change ships to a URL your team can click the same day it is written. For product builds, weeks two through six implement the core screens against real APIs, starting with the highest-traffic or highest-revenue routes. For migrations, the same period moves routes in traffic order with redirects and monitoring at every step.
The final phase is the part most projects skip: performance passes against Core Web Vitals on real devices, accessibility review, SEO verification against search console data, and a handover session with whoever maintains the site next. I consider the engagement done when your team can ship a change without me, not when the last screen merges.
Ask where the server-client boundary should sit in a component tree and listen for reasoning about data flow and bundle size rather than dogma in either direction. Ask how caching behaves in the App Router — a genuinely tricky area — and expect honesty about its sharp edges rather than hand-waving. Ask for live production URLs and run them through PageSpeed Insights during the call; the scores of past work are the most honest portfolio a web developer has.
Be cautious of two profiles: the developer who treats Next.js as templates-plus-plugins, because product work will exceed them quickly, and the one who cannot name a situation where Next.js is the wrong choice, because tools chosen on identity rather than fit produce expensive architecture. Verified client reviews on platforms with real hiring histories beat any portfolio page.
A five-page brochure site that changes twice a year does not need Next.js — a static site builder or even well-crafted plain HTML will be cheaper to build and to keep. An internal admin tool with a dozen users may be better served by an off-the-shelf tool builder than by custom development of any kind. And if your team is deeply invested in another stack it maintains well, a familiar framework beats a fashionable one — the wrong reason to adopt Next.js is that everyone else did.
Where it earns its complexity is exactly where this service lives: content that must rank, applications that must feel fast, and teams that want one React codebase spanning both. If your project falls outside that, I will say so in the first call and point you at the cheaper answer.
You approve milestones and a price before any build starts — no open-ended hourly surprises.
You see running software each week, not status reports, so you can course-correct early.
The person who scopes the work is the person who builds it — no junior layers, no agency markup.

With me, $15K–$100K. A marketing site with CMS, strong Core Web Vitals, and SEO fundamentals typically lands in the $15K–$35K band. Product dashboards with auth, roles, and data-heavy screens run $35K–$70K. Large migrations or full product builds with several integrations reach $100K. Quotes are itemized by route and feature so you can trim scope deliberately.
Marketing sites typically take three to six weeks; product applications eight to fourteen; incremental migrations run alongside normal business for six to twelve weeks depending on route count. A deployed preview exists from week one in every case, so progress is something you click, not a status report. Rush timelines are possible by cutting scope, never by cutting the performance pass.
Migrate off Create React App — it is deprecated and the ecosystem has moved on. The Pages Router is different: it still works and is maintained, so migrate when you will actively benefit from server components, streaming, or nested layouts, not for fashion. Either way, migrate incrementally by route with redirects and monitoring; big-bang rewrites are where traffic and budgets go to die.
