About Me

S
Available for opportunities

I'm a QA Team Lead with 7+ years of experience ensuring software quality across web, mobile, and API domains. I specialize in building scalable automation frameworks and mentoring QA engineers to deliver fast, reliable feedback loops.

I believe quality is not just a process — it's a culture. My mission is to shift testing left, eliminate manual bottlenecks, and integrate quality into every stage of the development lifecycle.
