Front-end development that performs
US-based front-end engineers shipping React, Next.js, Vue, and TypeScript interfaces — fast, accessible, and built for production traffic.
What this service delivers
Front-end development turns design into the interface your users actually experience. At NextGen, our US-based front-end engineers translate Figma into production-grade React, Next.js, and Vue applications engineered for performance, accessibility, and long-term maintainability.
We build front-ends for marketing sites, SaaS applications, internal tools, and consumer products. Whether you need a pixel-perfect marketing site or a complex data-heavy dashboard, our engineers ship code that stands up to real traffic and grows with your product.
Every interface we build is measured against real metrics — Core Web Vitals, Lighthouse, WCAG, and business KPIs — not just visual fidelity.
Why choose NextGen Coding
Front-end is where most software teams accumulate technical debt fastest. Under-invested front-ends produce brittle components, inconsistent state, and accessibility gaps that surface as user complaints months later. NextGen's engineers build with component discipline, typed contracts, and testing from the first commit.
Our team ships production React, Next.js, and TypeScript code that senior engineering leaders can hire against. When you eventually bring the codebase in-house, it reads like it was written by your own senior team.

Legacy modernization
Teams migrating from jQuery, Backbone, or old Angular to modern React or Vue.
Design system implementation
Companies operationalizing a design system as a shipped component library.
Performance rescue
Existing apps with poor Core Web Vitals, slow first paint, or bloated JS bundles.
Everything included in a NextGen build
React and Next.js applications
App Router or Pages Router, RSC where it fits, ISR/SSG/SSR chosen per route based on data freshness needs.
TypeScript throughout
Strict TypeScript, typed API contracts, and shared types across front-end and back-end.
Component libraries
Storybook-documented components with accessibility, variants, and visual regression coverage.
Design system implementation
Tokens, primitives, and composite components engineered from your design system.
State management
TanStack Query, Zustand, Redux Toolkit, or Context — chosen for the shape of your data, not fashion.
Forms and validation
React Hook Form + Zod schemas with typed submissions and consistent error surfaces.
Accessibility (WCAG 2.2)
Semantic HTML, keyboard navigation, focus management, and screen reader validation.
Performance engineering
Code splitting, image optimization, font loading strategy, and Core Web Vitals tuning.
Testing
Vitest or Jest unit tests, React Testing Library, and Playwright E2E — running in CI.
CMS integration
Contentful, Sanity, Sanity, Payload, and headless WordPress wired into your Next.js front-end.
Analytics and event instrumentation
GA4, Segment, PostHog, and custom event pipelines with typed event schemas.
SEO engineering
Semantic HTML, structured data, sitemaps, canonicals, and per-route metadata.
How the engagement runs
Repo and toolchain
Repo setup, TypeScript config, linting, formatting, CI, preview deploys, and design token pipeline.
Primitives and layout
Base primitives, layout shells, and shared providers built and Storybook-documented.
Feature build
Feature-by-feature build with weekly demos, staging deploys, and iterative feedback.
Test and accessibility coverage
Unit, integration, and E2E coverage added alongside every feature.
Performance and QA pass
Lighthouse, Core Web Vitals, and cross-browser QA on real devices.
Iteration and observability
Sentry, real-user monitoring, and iteration against real user behavior.
Transparent, US-market pricing
Feature build
Time-and-materials engagements for defined feature scopes. Blended rates $150–$220/hr.
Embedded engineer
One or more full-time front-end engineers embedded with your team. Monthly rate scales with seniority.
Fixed-scope build
Marketing sites and defined app modules delivered against a fixed price and milestone schedule.
All pricing is transparent and US-market calibrated. We don't compete on the lowest upfront number — we compete on delivering outcomes that generate the highest return on investment.
Results our clients experience
40% faster load times
A SaaS client's dashboard hit sub-1.5s LCP after we replaced their legacy front-end with a Next.js + React Query rewrite, unblocking enterprise procurement.
Accessibility compliance
A regulated-industry client reached WCAG 2.2 AA compliance across their product, clearing a procurement blocker with three Fortune 500 buyers.
Bundle size cut 62%
A retail client's PDP shrank from 1.8MB JS to 680KB after we refactored to per-route code splitting, with measurable revenue lift on mobile.
Thought leadership & technical writing
Next.js App Router in production
When to reach for RSC, when to stay on the client, and how to structure data fetching at scale.
React performance patterns
Memoization, list virtualization, and Suspense boundaries that actually move Core Web Vitals.
Design system rollouts
How to ship a design system without stalling product velocity.
Objections, addressed
Our current team can build this.+
Great — many of our best engagements augment strong internal teams during peak periods, or handle a specific high-leverage module while the internal team focuses on core product. We work as an extension, not a replacement.
React is overkill for our site.+
Sometimes. For simple marketing sites, Astro or a static generator can be a better fit — we'll say so. For anything with interactivity, state, or a growth roadmap, React or Next.js pays back quickly.
Front-end quality doesn't matter as much as back-end.+
It matters differently. Back-end failures crash the app; front-end failures quietly drop conversion, accessibility, and retention. Both need engineering discipline.
Frequently asked questions
Which front-end frameworks do you work in?+
Primarily React and Next.js, with Vue and Nuxt on select engagements. We also work in Astro for content-heavy sites and Remix when routing and forms benefit from its data model.
Do you write tests?+
Yes — Vitest or Jest for units, React Testing Library for components, and Playwright for E2E. Coverage runs in CI on every PR.
How do you handle design system work?+
We build tokens, primitives, and composite components in Storybook with visual regression via Chromatic or Percy. Consumers get typed props and documented usage.
Can you work with our existing back-end?+
Yes. Most of our front-end engagements integrate with an existing REST or GraphQL back-end. We define contracts up front and generate typed clients where possible.
Engineering discipline. US-based delivery.
NextGen Coding Company builds websites and software as measurable business assets, not decorative art. Our team combines rigorous engineering discipline with design and conversion strategy, and every deliverable is accountable to an outcome. Clients partner with a single US-based team that owns strategy, design, build, and post-launch iteration.
All work is performed by US-based engineers and designers. Our team's proximity to US business hours, cultural context, and buyer expectations produces web experiences that resonate with domestic audiences — a nuance offshore teams frequently miss. We serve clients from New York and across the country, from early-stage startups through Fortune 500 enterprises.
