What I'm looking for

I’m looking for an Agile QA role where I can own end-to-end testing, coordinate cross-functional teams, validate APIs and data, and support release readiness with clear defect triage and follow-up for stable launches.

I’m an ISTQB-certified Software QA Tester with 3+ years of experience across functional testing, backend validation, release QA, and defect management. I focus on owning testing end-to-end—planning, executing, validating fixes, and supporting stable releases.

At IGG INC as an Intermediate QA Tester, I develop weekly test plans tied to development milestones and partner with producers and developers to define test scope, surface edge cases, and communicate QA risks. I run functional and full-stack testing using Unity logs, ACK response tracking, and database verification, then track and triage 300+ Jira issues monthly with clear reproduction, severity, and validation notes.

Before this, I worked part-time with uTest on mobile apps and websites, where I documented usability and edge-case findings with screenshots/logs and severity assessments. Earlier at IGG INC, I built test plans and scripts, used playtesting and regression workflows to identify defects, and improved defect outcomes—supporting a 35% decrease in post-launch bug reports and achieving a 95% resolution rate with Redmine.
