How it works
Requirements
Definition of content models, complete page inventory, primary user flows, and technical constraints including CMS selection, authentication requirements, payment integration needs, and internationalization strategy.
Design System
Component library built in Tailwind CSS with consistent typography scales, semantic color tokens, spacing systems, and accessibility baselines meeting WCAG 2.1 AA standards — ensuring visual cohesion across all pages and devices.
Development
Next.js App Router implementation using Server Components for data fetching, dynamic route handlers for localized content, API route handlers for form submissions, and headless CMS integration for marketing team autonomy.
Performance
Image optimization with WebP/AVIF formats and responsive srcsets, font subsetting to minimize layout shift, strategic third-party script loading with defer and async attributes, and caching rules tuned for both static and dynamic content.
Launch
Vercel deployment configuration with custom domain setup, staging and production environment separation, analytics verification across GA4 and Search Console, and post-launch monitoring for error rates and Core Web Vitals regression.
