Senior QA Engineer / SDET

I served as the primary and lead QA engineer for Nova Wallet, a non-custodial iOS and Android Web3 wallet in the Polkadot and Kusama ecosystem supporting more than 80 chains. I also tested Nova Spektr, an enterprise desktop multisig wallet, while leading recurring QA strategy sessions and contributing to delivery management.

I created test plans, test cases, use-case scenarios, release quality gates, and a CI/CD-integrated automation strategy. I built end-to-end iOS and Android automation with Appium and BrowserStack, performed Playwright testing for the desktop web application, and used AI tooling for test-case generation, log analysis, and failure triage.

I tested wallet operations, on-chain transactions, staking, OpenGov governance, XCM transfers, NFTs, WalletConnect, dApp browser features, hardware wallets, biometric authentication, deep links, and fiat on/off-ramp integrations. I worked with Sentry, Firebase, Postman, Charles Proxy, TestFlight, Allure TestOps, and BrowserStack to investigate defects and improve release quality.

I led the mobile QA department for three applications of an international investment and trading platform. I developed test plans and test designs for Android and iOS applications and coordinated testing across emulators, real devices, device farms, frontend components, and backend services.

I tested microservice-based backend systems using RabbitMQ, Kafka, and gRPC APIs, including the migration of automated tests from REST to gRPC. I also built an automation framework and automation tools, conducted exploratory testing for new UI and proof-of-concept features, and reported results to stakeholders.

I collaborated with product, marketing, analytics, and engineering teams while acting as the lead for the mobile QA department.

I developed performance reporting and test-environment tooling for a banking processing automated system. My work included Docker-based tooling, CI/CD support, Python scripting, and NoSQL data handling.

I conducted performance and load testing for high-volume banking transaction workflows. I developed a reporting module that reduced reporting time by approximately 70%.

I worked as a Senior SDET and assistant lead on banking billing systems, focusing on performance and load testing in Agile and CI/CD environments. I created test data parameterization and scripts using Java, Python, and SQL.

I organized and controlled load-testing initiatives for banking and payment-processing systems, including resource management, test planning, scheduling, process improvement, and stakeholder coordination. I led daily and weekly stand-ups with developers, analysts, and functional testers.

I helped launch a complex performance and load test suite on time to ensure system stability. My automation tests, test sets, and monitoring improvements reduced time costs by up to 30%.
