What I'm looking for
I am a senior QA and test engineer with extensive experience in reliability-driven testing, release leadership, and improving quality processes across high-transaction and mission-critical systems. I have led deployments, developed complex test scripts, and served as a quality consultant to cross-functional teams.
My background includes ensuring platform stability during peak traffic events, mentoring QA analysts, and collaborating closely with product owners and developers to reduce production bugs. I combine manual and automation testing experience, working with modern test frameworks and tools to accelerate defect identification and resolution.
I bring strong problem-analysis skills, proficiency with CI/Git workflows, and hands-on experience with API, UI, performance, and usability testing. I seek opportunities where I can drive test strategy, improve release quality, and contribute to resilient, user-focused products.
