I build automated and accessible quality assurance for web, mobile, API, and enterprise platforms.

I'm currently strengthening regression coverage for Ontario's Student Assistance Program at the Ministry of Public and Business Service Delivery and Procurement. I develop VBScript automation in Micro Focus UFT, design functional tests, and lead accessibility testing for AODA and WCAG compliance.

I use Microsoft 365 Copilot and GitHub Copilot to improve code reviews, automation scripts, framework enhancements, requirements validation, and test-case design. I'm also exploring MCP-enabled Docker workflows and Playwright for reusable, scalable browser automation.

Previously, I led UAT, FOTA, and functional validation for T-Mobile and AT&T automotive cloud platforms at Harman, including device deployment testing before production rollouts. I built PostgreSQL validation and test-data scripts, automated Tableau and KNIME reporting, and coached validation and product support teams.

Across healthcare, mission-critical radio, and Android device projects, I've built Selenium, Java, TestNG, Maven, API, and SQL-based test coverage while managing defects and release validation. I bring hands-on experience across web, mobile, client/server, and 3-tier applications in Agile delivery environments.
