At MoryyaLab, I test client web platforms across booking, payments, CRM, APIs, and third-party integrations. I tested Stripe and Moneris payment flows, and my work helped reduce critical production defects by ~70% before launch.

I also designed and built an AI-assisted Node.js and Playwright tool that audits 120+ websites and produces a visual HTML report. Across my contract QA work, I’ve tested REST APIs, created reusable test resources, and investigated issues from the UI through logs and SQL; I’m ISTQB CTFL certified.
