Article Categories

Browse articles by subject area, from practical software engineering and front‑end development through to React, Next.js, JavaScript, CSS, accessibility, performance, technical SEO, headless CMS work, architecture, leadership and delivery. These categories group related writing from John Kavanagh's technical blog so readers can move from a broad topic into focused article collections.

Some categories cover implementation detail, such as browser behaviour, rendering, testing and platform debugging. Others connect technical decisions to search visibility, content structure, maintainability and engineering leadership. The taxonomy also keeps development‑led, service‑related and editorial material close enough to compare without turning the archive into a flat list of tags. Use this index as the starting point for exploring the main themes across the article archive.
