At RockUp, I owned the QA process for a React Native app and web product, from requirements analysis and test strategy through release validation and production checks. I built a Kotlin automation framework with JUnit, Selenide, and Appium, achieving a 95% pass rate across iOS and Android.
I validated end-to-end workflows across REST APIs, WebSocket, PostgreSQL, mobile UI, and analytics integrations. I also tested payment flows with Stripe, Apple Pay, and Google Pay, and integrated automated tests into GitHub Actions as release-quality gates.
At Playrix, I developed Python automation for mobile product scenarios, combining Appium UI flows with API and server-side validation. I built helpers to verify backend data and analytics events, and stabilized flaky tests.
At Intermedia, I developed Java and Kotlin mobile automation and improved the test pass rate from 60% to 91%. Earlier, as a Manual QA Engineer at Intermedia, I created test plans and cases, tested mobile apps and APIs, and investigated customer issues using logs and network behavior.
