I've tested web, mobile and SaaS products for clients in Ukraine, the US and Europe through Onix Systems and client contracts. My work spans native and Flutter iOS/Android apps, cybersecurity SaaS, ticketing platforms and enterprise LMS products.
On a cybersecurity SaaS platform, I tested Stripe escrow and failure scenarios, Sumsub KYC flows, database-migration integrity, APIs and cross-browser behaviour. I also built Playwright and TypeScript E2E tests using the Page Object Model and improved visual-regression stability with Checkly.
I've accepted iOS and Android releases through TestFlight, Firebase App Distribution, the App Store and Google Play. For ticketing products, I tested purchases, QR check-in, on-site sales, push notifications, deep links, geolocation, offline states, LiqPay and Stripe payments.
Since 2025, I've been building SmartQA, my TypeScript framework for generating traceable QA documentation. It connects requirements to test cases, Gherkin scenarios, automated tests and traceability matrices while surfacing coverage gaps and validating quality gates.
