What I'm looking for

I seek roles where I can lead QA initiatives, expand automation and AI-driven testing, mentor teams, and integrate quality into CI/CD workflows.

I am a Senior QA Engineer with 10+ years of experience in software quality assurance, combining manual and automated testing to deliver reliable products. I specialize in modern test automation frameworks and CI/CD integration, and I actively incorporate AI-driven tools to enhance testing strategies.

At Endava I developed and maintained Cypress test suites in JavaScript and TypeScript, supported visual regression testing, and promoted early bug detection by collaborating closely with developers and product owners. I mentor junior engineers and help teams transition from manual to automated testing.

Previously, as QA Lead at Flexiti, I led a team across multiple applications, organized sprint planning and testing strategy, and defined processes to identify cases for automation. My earlier roles at Accenture and Moravia built my foundation in test case design, localization workflows, and cross-domain testing.

I co-founded and manage a large RPG-focused YouTube channel where I oversee content, QA of platform features, and lead a team of 10+. I am committed to continuous learning, particularly in AI-enhanced testing, and to improving processes and documentation to increase product quality.
