What I do
- Product Audits & Testing: Functional, Regression, Smoke — focused on release risk, not generic checklists
- Accessibility WCAG 2.1 / 2.2 AA: web and mobile, defensible ADA conclusions with a reusable audit protocol delivered at the end of the engagement
- Accessibility for Complex UIs: custom components, dynamic content, modals, multi-step forms, and RTL contexts
- ADA Compliance Consulting: structured gap analysis for legal defensibility, not just a technical pass/fail result
- AI Product Validation: LLM output quality, agentic workflows, hallucination detection, edge cases, prompt-to-output consistency
- AI Agent Testing: MCP integrations, tool call accuracy, policy application validation, execution log integrity
- Prompt-to-Output Regression: detecting quality drift between model updates and prompt evolutions
- Data-Driven QA: I use your analytics and monitoring to define scope and measure quality impact
- Light Automation: I build what saves time, not what creates technical debt
