What I'm looking for

I seek a role where I can drive QA process improvements, work in cross-functional teams, mentor others, and deliver high-quality products in international, English-speaking environments.

I am a Senior QA Engineer with five years of hands-on experience testing products across blockchain, fintech, e-commerce, healthcare, education (LMS), real estate, and startup environments.

I have delivered more than 20 projects, working independently to manage end-to-end QA processes and also collaborating with developers, analysts, and product managers to improve workflows and product quality.

My technical toolkit includes TestRail, Postman, Charles, JMeter, SQL, Git, Figma, DevTools, BrowserStack and mobile/desktop platforms; I regularly leverage AI tools such as ChatGPT and Midjourney to streamline test work and reporting.

I have experience mentoring colleagues, presenting at internal meetups, and running QA processes in English-speaking international teams, owning test planning, execution, documentation and issue resolution to ensure timely, high-quality releases.
