// ABOUT

I'm a QA Engineer with 8+ years of experience in software testing.

Throughout my career I've worked at product companies and startups, testing desktop, mobile, web, and API applications. Most of my experience is rooted in manual testing: functional, regression, exploratory, integration, acceptance, and end-to-end. I've been involved in every stage of the development lifecycle — from requirements analysis and test planning through to releases and post-release support.

One of my core areas is web and API testing. I have experience with iOS and Android apps on real devices and emulators — including push notifications, app lifecycle, payments, subscriptions, and release builds. I've also worked extensively with SaaS web products, testing auth flows, user accounts, payment systems, and API integrations using Postman, Charles Proxy, and browser DevTools.

Beyond manual testing, I have hands-on automation experience with Python, PyTest, Selenium WebDriver, JavaScript, and WebdriverIO. I'm currently learning TypeScript and Playwright. I actively use AI tools — ChatGPT, Claude, Gemini, and Claude Code — for requirements analysis, documentation review, test documentation preparation, and learning new technologies.

I'm currently at Trackit Labs, where I'm responsible for quality on a web platform for real-time Padel match analytics. My day-to-day includes requirements analysis, risk assessment, API testing, release preparation, and post-release support.

Going forward, I want to continue growing in mobile QA and strengthen my automation skills in parallel. I enjoy working on products where quality directly impacts user experience and business outcomes — and I'm looking for opportunities to keep growing professionally.

// BEYOND CODE

On the personal side, I'm a family person — I have a two-year-old child and my family is a central part of my life. In my free time I enjoy snowboarding, cycling, tennis, and video games. I'm drawn to an active lifestyle, exploring new technologies, and continuous growth — both professionally and personally.
