Cracow, Małopolskie, Poland
QA Engineer with nearly 15 years of experience, focused on delivering high-quality products through strong manual testing practices and a deep attention to detail. Over the past year, I’ve been working closely with Data Quality, validating data accuracy and reliability across systems and pipelines. While Manual QA remains a strong foundation, I bring solid, hands-on experience in test automation, designing, maintaining, and evolving automated test suites using Cypress, Playwright, and RestAssured across web and API layers. I have contributed to automation strategy improvements, including framework migrations, test stability, and CI/CD integration, ensuring automation provides real and measurable value. Beyond testing, I actively contribute to product and team processes by reviewing requirements, participating in refinements, improving Jira workflows, collaborating closely with engineering and product teams, and helping optimize QA practices across the delivery lifecycle. Currently, I’m expanding my knowledge of Salesforce, working toward initial certifications for Admin, Developer, and Agentforce. Outside of work, I’m deeply passionate about gaming, and I aspire to bring my quality-driven mindset and technical skills into the game development industry one day.
