React & Next.js Applications.

Corporate sites, B2B portals, and SaaS dashboards engineered on Next.js — with strict Core Web Vitals budgets, type-safe data fetching, and design systems built for teams to extend.

The Shift

From what's slowing teams down, to what unlocks growth.

01The Ceiling

Legacy React apps hit a wall.

Client-only React SPAs made sense five years ago. Today they leak bundle size, ship blank HTML to crawlers, and force every team member to reinvent auth, routing, and caching. Marketing metrics stall because pages render slowly on mid-range mobile devices, and engineering velocity slows because every new feature has to negotiate with a growing pile of ad-hoc patterns.

02The Modern Stack

Streamed, server-first, and typed end-to-end.

Modern Next.js unlocks server components, streaming, and edge rendering out of the box — but only if the app is architected around those primitives from day one. I design component systems that stay maintainable as the team grows, and route boundaries that keep the client bundle small no matter how many features you add.

  • Server components + streaming for instant first paint.
  • Type-safe data fetching with generated client SDKs.
  • Design-system component library scaffolded for team reuse.
  • Lighthouse budget enforced on every pull request.

Modern Next.js unlocks server components, streaming, edge rendering, and image optimization out of the box — but only if the app is architected around those primitives from day one. I design component systems that stay maintainable as your team grows, and route boundaries that keep the client bundle small no matter how many features you add.

Every build ships with type-safe data fetching, error boundaries at every layout, and a Lighthouse budget that CI enforces on every PR.

What's included in this build

Every react & next.js applications engagement is a premium, end-to-end delivery tailored to your specific business rules.

Design System

A component library seeded with the exact primitives your product needs — buttons, forms, tables, modals, empty states — theme-tokenised for future rebranding.

Type-Safe Data Layer

Server components with strongly-typed fetchers, generated schemas, and a caching strategy documented per endpoint.

Auth & Permissions

OAuth / SSO / magic-link auth wired end-to-end, with role-based access enforced at the route boundary — not sprinkled through UI code.

SEO & Metadata

Per-page metadata, canonical URLs, sitemap.xml, robots.txt, and JSON-LD (Article, BreadcrumbList, FAQPage, Product) generated from your content model.

Analytics Integration

Privacy-first analytics (Plausible, PostHog, or Vercel Analytics) wired with server-side event forwarding to bypass ad blockers.

CI Performance Budget

GitHub Actions running Lighthouse on every PR. Bundle size, LCP, and CLS regressions fail the check before merge.

At a glance

  • Type-safe data fetching with server components
  • Design-system component library scaffolded for reuse
  • Core Web Vitals budget enforced in CI
  • Accessible-by-default: WCAG 2.2 AA baseline

Frequently Asked Questions

Common questions about react & next.js applications engagements.

Should my app be SSR, SSG, or ISR?
All three, depending on the route. Marketing pages should be static, product listings incremental, dashboards server-rendered per request. I map every route to its right mode during architecture — you don't have to decide.
Do I have to use TypeScript?
For anything you plan to maintain past six months, yes. TypeScript catches an entire class of bugs at build time and makes onboarding new engineers dramatically faster. I write all new code in TypeScript.
Can my team take over the codebase afterwards?
That's the goal. Every build ships with an architectural README, per-module ownership notes, and a handoff walkthrough. If you have engineers on staff, I train them on the specifics of the codebase before we part ways.
Can you upgrade my existing React app instead of starting fresh?
Often yes. I run an audit first to see whether an incremental migration (route by route, with the old app and new app served side by side) is cheaper than a rebuild. About 60% of the audits end with 'incremental is the right call'.
