Kateryna D.
QA Engineer | SaaS, API & Web Testing | AI-Assisted QA
Hi! I'm a QA Engineer with 6+ years of experience testing web applications and APIs across different product domains, including SaaS, fintech, and enterprise products. I help teams deliver stable, reliable software by combining functional, regression, exploratory, integration, accessibility, and API testing. I enjoy understanding how systems work end-to-end, finding edge cases, and improving product quality before issues reach users. My experience includes: • Web & API testing (Postman, REST APIs) • End-to-end and integration testing • Test case design and QA documentation • Jira, TestRail, Chrome DevTools • SQL basics • Accessibility testing • AI-assisted QA workflows I work well both independently and as part of cross-functional teams. I'm proactive, detail-oriented, and comfortable working with startups as well as established product companies. If you're looking for someone who genuinely cares about product quality and communicates clearly throughout the process, I'd be happy to help.
