Performance Engineering

Every application ships with a Lighthouse 100 baseline.

Performance is not a post-build concern. SSR/SSG rendering strategy selection, critical path optimisation, edge caching architecture, and Core Web Vitals engineering are designed in from the first route.

Route-level rendering decisions

Each route in the application has an explicitly chosen rendering strategy — SSG for static content, ISR for time-sensitive data, SSR for real-time personalisation, CSR only for authenticated UI.

Structured data at every route

JSON-LD schema deployment is automated per content type — WebPage, Article, Product, FAQPage, BreadcrumbList — making every route SERP-feature eligible and AI-citation ready from launch.

Production observability built in

Error monitoring (Sentry), uptime checks, performance budgets, and Real User Monitoring via Vercel Analytics or self-hosted are configured before launch, not retrofitted after incidents.

How We Build

MVP to production in 8–12 weeks

A structured five-stage programme where architecture decisions, SEO strategy, and performance engineering are made at the specification stage — never retrofitted after launch.

Phase 01 — Architecture

Technical Specification & System Design

Stack selection, rendering strategy map, data model design, API architecture, SEO technical specification, performance budget, and infrastructure plan. Every decision documented before a line of code is written.

Phase 02 — Design

UX Design & Design System

Component-level design system, responsive prototypes, interaction design, and accessibility audit before development begins. Design tokens exported directly to Tailwind config.

Phases 03–04 — Build

Iterative Development & Feature Sprints

Two-week sprints with staged deployments to preview environments. Weekly demo calls. SEO architecture, schema markup, and performance optimisation integrated throughout — not post-build.

Phase 04 — QA

Quality Assurance & Lighthouse Certification

Vitest unit tests, Playwright E2E, cross-browser QA, security audit, Lighthouse 100 certification, structured data validation, and AI crawler access verification before release.

Phase 05 — Launch

Deployment, Monitoring & Handover

Production deployment, CI/CD pipeline, observability setup (Sentry, analytics), documentation, knowledge transfer, and 30-day post-launch support with on-call SLA.

Custom Web Development

Why Next.js over a standard React SPA for SEO?
A standard React SPA renders entirely in the browser (CSR) — meaning Googlebot receives near-empty HTML on its first crawl. It may re-render with JavaScript later, but this is inconsistent, delayed, and produces lower-quality indexation. Next.js with SSG or SSR delivers fully rendered, semantic HTML on the first HTTP request, with no JavaScript execution required for indexation. This is the difference between a site that ranks and a site that is technically invisible to search engines.
What is the difference between SSG, SSR, and ISR?
SSG (Static Site Generation) pre-renders pages at build time — fastest possible delivery, best for content that changes infrequently. SSR (Server-Side Rendering) renders on each request — ideal for personalised or real-time content. ISR (Incremental Static Regeneration) pre-renders and caches, then regenerates in the background when data changes — the best balance of performance and freshness for content-heavy sites. We select the appropriate strategy per route, not per application.
Do you build MVPs or full-scale production applications?
Both — but we architect both for production from day one. An MVP built with shortcuts and technical debt becomes expensive to scale. We build MVPs using production-grade architecture, TypeScript, and CI/CD pipelines so the transition from MVP to scaled product is an extension of what already exists, not a rewrite.
How do you handle SEO for dynamic, data-driven pages?
Next.js App Router's generateMetadata function allows server-side metadata generation per route, including dynamic title, description, OpenGraph tags, and canonical URLs derived from database or CMS data. JSON-LD schema is generated server-side per content type and injected into the page head. Dynamic sitemaps are generated via a dedicated /sitemap.xml route handler. Every dynamic page in the application is fully SEO-configured at the server level without client-side workarounds.
