React & Next.js Development
Fast, accessible frontends and full-stack applications using React 19, Next.js 15, and TypeScript — Server Components, SSR, 90+ Lighthouse scores, and WCAG 2.1 AA out of the box.
Frontends that perform where it counts
A 2-second delay in page load time reduces conversions by 7%. A Largest Contentful Paint above 2.5 seconds hurts your Google ranking. These are not abstract metrics — they are the direct link between frontend quality and business outcome. We build React applications that achieve 90+ Lighthouse scores by default because we treat Core Web Vitals as non-negotiable requirements, not post-launch polish.
Next.js React Server Components let us render content on the server and stream it to the browser — eliminating the blank-screen flash of client-rendered SPAs and reducing the JavaScript bundle shipped to the user. For pages that need interactivity, we selectively hydrate only the components that require it, keeping total JavaScript payload minimal while delivering a fully interactive experience.
TypeScript-first, accessible, maintainable
We write TypeScript with strict mode enabled — not for the sake of it, but to catch entire categories of runtime errors at compile time, make refactors safe, and give your IDE the information it needs to autocomplete the codebase correctly. A TypeScript-first codebase is objectively easier to maintain six months after it was written, especially when a new developer joins the team.
Accessibility is built in from the start. We test against WCAG 2.1 AA using axe-core automated tools and manual keyboard and screen reader testing. Correct semantic HTML, proper focus management, and ARIA attributes are not retrofitted — they are part of every component from first commit.

Core Web Vitals — first-class, not afterthought
Google's Core Web Vitals directly influence search rankings and user experience. LCP (how fast the main content loads), CLS (whether the layout shifts as you scroll), and INP (how quickly the page responds to interaction) are engineering constraints we design against from the first commit — not metrics we retrofit after complaints.
React Server Components let us move data fetching and heavy computation to the server, shipping a minimal JavaScript bundle to the browser. Images are served in WebP or AVIF via Next.js Image, fonts are subset and preloaded, third-party scripts are loaded with the Script component's deferred strategy, and critical CSS is inlined to unblock rendering. The result is a site that feels instant to users and ranks well in search.
Choosing the right rendering strategy
| Strategy | Best for | SEO | Freshness |
|---|---|---|---|
| SSG (Static) | Marketing pages, blogs, docs | ✅ Best | ⏱ Build time |
| ISR | Product pages, news feeds | ✅ Great | 🔄 Per interval |
| SSR | Personalised pages, dashboards | ✅ Good | ⚡ Per request |
| CSR (React SPA) | Internal tools, admin panels | ❌ None | ⚡ Per request |
| RSC Streaming | Hybrid apps with partial hydration | ✅ Great | ⚡ Per request |
From design to deployed — the development roadmap
Discovery & Design Handoff
Week 1We review your Figma designs (or create wireframes if none exist), define the component library structure, agree on the tech stack, and document API contracts with your backend team.
Component Library Setup
Week 1–2Storybook is configured and the design system is implemented — typography, colour tokens, base components (Button, Input, Card, Modal) — before any page is built. This prevents duplication and enforces consistency.
Route & Layout Architecture
Week 2App Router folder structure, shared layouts, loading/error boundaries, auth guards, and metadata configuration are set up. The skeleton works end-to-end before feature pages are filled in.
Feature Development
Weeks 3–NDevelopment runs in 2-week sprints. Each sprint delivers working pages to a Vercel preview URL. You review in a real browser on real devices — no localhost screenshots.
Testing & Accessibility
Each sprintVitest unit tests for utilities and hooks, Playwright E2E tests for critical user flows, axe-core accessibility scans, and a Lighthouse audit after each sprint. Issues are fixed before moving forward.
Optimisation & Go-Live
Final sprintBundle analysis with @next/bundle-analyzer, image optimisation, font subsetting, third-party script audit, Core Web Vitals baseline measurement, then production deployment to Vercel or AWS with caching rules configured.
Handover & Support
Post go-liveComponent library documentation, deployment runbook, environment variable guide, and a 30-day support window for any post-launch issues or Lighthouse score regressions.
