I'm a QA Automation Architect and Senior SDET with 18+ years of experience building automation frameworks and testing infrastructure for web, mobile, desktop, APIs, messaging systems, databases, and performance testing.
I design maintainable test solutions, CI/CD pipelines, and developer tooling using Java, Python, JavaScript/TypeScript, Kotlin, and C#. My current interests include JUnit 6, Playwright, developer productivity, and applications of AI in software testing.
I hold a PhD in theoretical physics from Odessa I. I. Mechnikov National University, where my research focused on the physics of water and liquids.
Additional experience: Selenide, Shell, GitLab CI, PostgreSQL, MySQL/MariaDB, Oracle Database, Microsoft SQL Server, JMS, AWS, and Microsoft Azure.
Testing domains: Web, mobile, desktop, API, database, messaging, and performance.
