We author semantic HTML5 with proper landmarks, headings, labels, and ARIA only when needed. Keyboard navigation, focus management, color contrast, and screen-reader support are built in. This improves usability, search visibility, and compliance with WCAG—so all users, including those with disabilities, can use your product confidently.

We implement scalable CSS with Tailwind, CSS Modules, or BEM, using variables, fluid spacing, and modern layout primitives like Grid and Flexbox. Our approach prevents cascade conflicts, reduces bloat, and supports dark mode and theming—delivering consistent, maintainable design systems across pages and micro frontends.

We write clean, framework-agnostic JavaScript with TypeScript types for safety and maintainability. Progressive enhancement ensures core features work without JS, while modules, events, and Web Components enable reusable UI. We avoid unnecessary dependencies, minimizing payloads and improving long-term stability.

We pursue Core Web Vitals excellence: critical-path CSS, code splitting, defer/async, lazy loading, prefetching, and image optimization. Lighthouse and WebPageTest guide continuous tuning. The result is fast First Contentful Paint, low CLS, and smooth interactions—even on mid-range devices and slow connections.

We implement crawl-friendly markup, headings, canonical tags, robots directives, Open Graph/Twitter cards, and schema.org JSON-LD. Clean URLs, sitemaps, and accessible content structures help search engines understand your pages—improving discoverability and click-through rates without resorting to gimmicks.

We test across modern browsers and devices with responsive breakpoints, safe CSS features, and progressive fallbacks. Automated checks (Playwright/Cypress), visual regression, and accessibility audits catch issues early—ensuring your experience works reliably for every user, everywhere.
