I'm a Senior QA Engineer at IDT Corporation, validating Linux-based telephony, backend, and release-sensitive systems for U.S. customers.

I investigate integration failures across REST APIs, Oracle/SQL data, Linux services, configurations, and server-side logs, delivering traceable evidence and reproducible Jira defects. I also coordinate release risks, blockers, retesting, and validation evidence with Agile teams.

I've built AI-assisted QA workflows using Claude Code and Playwright-oriented tooling to improve test planning, regression coverage, defect drafting, release summaries, and QA knowledge organization.
