Web development

Practice

Web development

Websites and web applications built to be fast on modest phones, usable without a mouse, and easy for the next developer to understand.

Publishing sites

Company and product websites with a small set of well-structured pages, static or lightly managed.

Content platforms

Editorial sites with editors, workflows and search on a content system selected for your team.

Web applications

Authenticated portals, dashboards and internal tools with databases, roles and integrations.

Baseline, every build

  • Semantic HTML and a single, logical heading structure per page
  • Layouts verified at phone, tablet and wide-screen sizes
  • A page-weight budget agreed and checked
  • Forms that preserve input and explain errors
  • HTTPS, security headers, maintained dependencies
  • Unique titles, descriptions, sitemap and robots file
  • Every third-party script listed and approved by you

On complexity

Each dependency is a future maintenance task and a possible security issue. We prefer fewer, well-understood components and will explain when something heavier is genuinely warranted.

Integrations with payment, booking, email or your own systems are documented: what data passes, where, and why.

Hosting you control

Hosting, domains and backups are set up in your accounts with written instructions. If we disappeared tomorrow, your site would keep running and another developer could pick it up.
