TLEX Dev is a practical web accessibility and standards site for developers, public-sector teams, and anyone tired of scanner-only compliance theater.
I write field notes, code fixes, governance lessons, and real-world accessibility guidance from the work of cleaning up public websites, PDFs, videos, forms, navigation, and systems that should have been fixed long before they reached users.
Practical accessibility. Real engineering. No magic overlays.
Web Accessibility
WCAG fixes, semantic HTML, keyboard navigation, contrast, forms, headings, links, ARIA when it actually helps, and the manual testing scanners cannot replace.
Public-Sector Web Cleanup
Legacy content, CMS sprawl, PDFs, videos, outdated pages, governance gaps, and the weird reality of fixing government websites without pretending the mess is simple.
Standards & Documentation
Repeatable patterns for teams: how to write accessible links, document fixes, test keyboard navigation, handle downloadable documents, and prove good-faith remediation without relying on scanners alone.
A11y Ronin Notes
Field notes from accessibility work in the real world: the bugs, the process failures, the almost-compliant traps, and the fixes that actually hold up.

20,000 Accessibility Issues Later: What Web Teams Need to Learn
Built from real cleanup work.
After helping reduce a large public website’s accessibility issue count from roughly 20,000 reported issues to fewer than 100 in under 90 days, I started documenting the practical lessons that scanners, committees, and policy documents often miss.

Governance gaps
Helping teams understand that accessibility is not one person, one plugin, or one dashboard.
