Quality Engineering & Automated QA Testing
AI-driven self-healing test automation suites (Playwright, Cypress, Selenium), visual regression testing, and performance load testing achieving 92%+ automated test coverage and zero production defects.
Self-Healing Playwright & Cypress Automation
Resilient test scripts automatically adapting to DOM changes and dynamic element IDs, reducing test maintenance overhead by 80%.
Visual Regression & UI Pixel Validation
Percy and Applitools visual AI test suites comparing snapshot diffs across viewport resolutions and browsers to catch visual regressions.
High-Concurrency Performance & Load Testing
k6 and JMeter load test scripts simulating up to 100,000 concurrent virtual users to identify database locks and API latency spikes before release.
Continuous Security & DAST Profiling
OWASP ZAP dynamic application security testing (DAST) embedded into GitHub Actions pipelines to block vulnerable PR merges automatically.
