Who Is Jason?

I'm a software engineer with nearly two decades of enterprise experience, helping Fortune 100 organizations achieve WCAG 2.2 AA compliance, cutting legal and operational risk.

At Dell Technologies, I've raised conformance rates by double digits, cut high-severity defects by a third, and improved the digital experience for millions of customers with disabilities. Current projects include a vector-augmented workflow that pulls from fragmented documentation to generate accurate, issue-specific reports - improving conformance while reducing documentation overhead for our accessibility testing team.

Outside of Dell, I've spent nearly a decade consulting for government entities as a full-service accessibility expert - driving testing, remediation, and long-term strategy. My approach is practical and impact-focused, helping teams consistently deliver more inclusive, compliant, and user-friendly software.

What I'm Working On

Accessibility Reporting Tool

Internal platform that centralises manual and automated accessibility test results, generates documentation, syncs with Jira, and powers compliance dashboards.

Overview

Centralized platform that aggregates accessibility test results, syncs issues with Jira, and provides exportable dashboards for compliance tracking.

AI-assisted workflows standardize issue documentation, reduce triage effort, and help testers surface high-impact problems faster.

Government Accessibility Consulting

Freelance audits, VPATs, remediation, and engineering guidance for state and local agencies.

Overview

Ongoing consulting for regional government agencies, focused on improving digital accessibility and maintaining WCAG compliance.

I serve as a hands-on accessibility partner - handling audits, writing VPATs, advising on procurement, and remediating issue. Projects often involve modernizing legacy WordPress and PHP-based sites, implementing inclusive design patterns, and helping agencies establish sustainable long-term accessibility practices.

Areas of Focus

Accessibility Engineering

Deep experience with WCAG compliance, ARIA design patterns, and building automated and manual test processes. I work closely with legal, QA, and engineering teams to scale accessibility across large codebases.

Frontend Development

Focused on accessibility-first React apps. I build scalable, tested UI components and collaborate with designers and developers to ship usable, inclusive interfaces.

Backend & Infrastructure

Build and maintain Node.js APIs, design MongoDB schemas, and deploy to AWS. I also handle scripting and automation for things like CI workflows, reporting, and issue triage.

Applied Accessibility Leadership

I lead accessibility work with a deep understanding of W3C ARIA Authoring Practices - particularly for complex widgets like menus, tabs, trees, and comboboxes.

I specialize in embedding WCAG 2.2 AA compliance, Section 508, EN 301 549, and related global standards into SDLC pipelines. I've scaled test workflows, mentored engineers, and trained full teams on accessible implementation.

Tools like Axe, ANDI, Lighthouse, NVDA, JAWS, and VoiceOver are core to my daily work. I build reliable processes that surface real issues and drive them to resolution.

Whether writing VPATs, influencing procurement, or coaching design reviews, I focus on systemic improvements and sustainable accessibility maturity.
