Hi, I’m Hanan Gershon, a senior QA engineer with extensive experience in mission-critical backend services and data platforms. I specialize in defining and executing robust API and integration testing strategies to ensure reliability and performance across cybersecurity, health tech, and insurance tech domains.
I bring hands-on skills in data integrity validation with advanced SQL (PostgreSQL, MySQL), plus automation using Python, Cypress, and Playwright. I’ve led QA strategy, mentored teammates, and integrated TestRail with GitLab to streamline test cases and bug tracking. I’m actively exploring QA methodologies for AI/ML systems and enjoy collaborating with cross-functional teams to deliver high-quality software.
