About

I'm Christopher Sullivan, a blind accessibility professional based in Texas. I use NVDA, JAWS, and VoiceOver every day — the same tools I test with.

My testing focuses on the barriers that automated checkers miss or understate: text resizing, reading order without CSS, and form issues. When I report a problem, it's one I've experienced firsthand as an assistive-technology user, not a warning copied from a scanner.

I also build my own accessibility testing tools, which keeps my manual technique sharp and my understanding of browser and screen-reader behavior current.

I'm currently completing the DHS Trusted Tester certification process for Section 508 and WCAG evaluation. IronShuttle is my independent, deliverable-based subcontract practice — audits, findings, guidance, and retesting, done solo at my desk.
