About Me
Hi! I'm a Quality Engineering Leader & Consultant with over 8 years of hands-on engineering experience. I've led successful digital transformations at FinTech and HealthTech companies, where I reduced regression & manual testing time by 80% and built scalable TestOps practices from scratch.
I specialize in establishing modern QE functions, implementing test automation frameworks, and developing CI/CD pipelines with comprehensive data seeding mechanisms. My approach combines strategic leadership with deep technical expertise, helping teams adopt DevOps and TestOps practices while building high-performing engineering cultures.
