At GMI Software, I lead mobile test automation with Maestro, Playwright, and Appium to reduce release time for apps on the Apple App Store and Google Play. I also developed a custom bug reporting tool to speed up client feedback.

I designed E2E QA processes and facilitated architecture workshops and technical consultancy sessions. My testing spans regression, smoke, performance, API, and A/B testing across platforms.

At E Net Production, I coordinated a QA team of 10+ on an e-commerce project and optimized QA processes across STLC stages. I also developed and maintained Cypress test scripts and integrated testing into CI/CD pipelines.

I’ve tested automotive software and video streaming apps at Better Software Group / Spyrosoft, and games at StoryPop Games. In personal projects, I created the Laga Mobile App and a management tool for Maestro automated mobile tests.
