What I'm looking for

I’m looking to take ownership of QA across system, API, and automation testing—leading complex projects, troubleshooting fast, and collaborating cross-functionally to deliver reliable integrations and secure performance.

I’m a Senior QA Engineer with 10+ years of experience in manual, system-level, API, and automation testing. I test networking, web, performance, databases, security, integrations, and client/server workflows, handling test planning and cases, bugs, and reporting. I’m known for multitasking, troubleshooting, and solving complex problems while working independently and with cross-functional teams.

Recently, I’ve led and managed QA for Web and API projects at Gigsberg using Selenium, Postman, SQL, Jira, and TestRail, including testing multiple payment systems. I also tested integrated systems across multiple services at Saito Tech, led desktop/mobile testing at Allseated (platform and complex 3D event experiences), and worked on cybersecurity/network security and firewall testing at Checkpoint. My core strength is owning quality end-to-end across complex, real-world technical environments.
