Hire the Best XSLT Specialists
in the United States

I help businesses, organizations, and government agencies make their websites, web apps, and digital documents accessible, compliant, and easier to use for everyone. I specialize in WCAG 2.1/2.2 AA, Section 508, ADA digital accessibility, PDF remediation, VPAT®/ACR reporting, and accessibility training. My audits are manual-first, detailed, developer-friendly, and built to uncover the real accessibility issues automated tools often miss. If you need a clear accessibility audit, PDF remediation, VPAT/ACR, remediation guidance, team training, or a final retest after fixes are made, I can help you get it done accurately and professionally. I provide free, no-obligation estimates. No back-end access is needed to start. Just send your URL, PDF, or document details, and I can review the scope and provide the time and cost for a thorough accessibility review. What I Can Help With Web Accessibility Audits Manual WCAG 2.1/2.2 AA and Section 508 audits for websites, web apps, dashboards, forms, checkout flows, login areas, dynamic components, and software platforms.

Why Clients Hire Me Accessibility work needs more than an automated scan. Automated tools are helpful, but they miss many real-world accessibility barriers and often produce false positives. My process combines industry-standard tools with hands-on manual testing so your team gets accurate findings, clear explanations, and guidance they can actually use. Government agencies, businesses, nonprofits, ecommerce brands, and software teams trust my work because I focus on practical results: finding the issues, explaining how to fix them, retesting after remediation, and helping document conformance through accessibility statements and VPAT/ACR reports. I also bring real accessibility education and product experience to my work. I have created public accessibility software for WordPress and have presented on web accessibility, WordPress accessibility, and the connection between accessibility and SEO. If you need an accessibility audit, PDF remediation, VPAT/ACR, team training, or help making your site or documents accessible, send over the details and I’ll be happy to provide a clear estimate.
