What I'm looking for

I seek a senior QA role focused on performance and API testing where I can lead teams, improve QA practices, implement efficient test automation, and mentor juniors in a product-driven company that values measurable quality gains.

I am a performance-focused Quality Assurance lead with over 8.5 years of experience in performance, database and manual testing for web and mobile applications. I excel at creating high-quality, reliable software products and leading teams to improve QA practices and reduce defect rates.

I have driven measurable outcomes — improving page performance from 10 sec to 5 sec, reducing API count from 24 to 11 while increasing user base by 2%, and contributing to an in-house Journey Builder that "reduces the cost of almost 80 milliion every year" compared to a third-party tool. I also developed Tedboard, lowering cloud load-test costs by 20% and cutting environment setup time from 48 hours to 5 minutes.

I enjoy mentoring and enabling teams, onboarding test cases into structured management, and running end-to-end testing across services and platforms. I focus on practical QA engineering, automation, and performance practices, and I routinely deliver companywide training on tools like JMeter to raise team capability.
