What I'm looking for

I’m seeking a collaborative role where I can lead QA strategy, expand automation and performance testing, mentor teams, and drive measurable quality improvements in CI/CD environments.

I am an ISTQB-certified software test engineer with six years of hands-on experience in functional and non-functional testing. I lead end-to-end QA strategy, build CI/CD-integrated automation frameworks, and mentor teams to elevate testing maturity.

I drive measurable improvements—achieving 80% automation coverage, uncovering bottlenecks that improved page-load times by 30% and reduced server response latency by 25%, and cutting mean time to resolution by 50%. I also developed API automation pipelines that reduced manual regression effort by 60% and accelerated release cycles by 20%, while ensuring 95%+ accessibility compliance and 98% on-time delivery with zero post-release defects.
