👋 About Me

Who I Am

I'm a Software QA Engineer / SDET currently working at Cognizant India, with prior experience at Tata Consultancy Services. I specialise in designing end-to-end test strategies for web, mobile, and telecom applications.

I've worked across diverse domains — Telecom (Ericsson), Banking (CIBC), and Defense Technology (L3Harris) — bringing deep QA expertise to every project and client I've served.

Passionate about shift-left testing, automation frameworks, and building quality into every stage of the SDLC. Beyond testing, I'm trained in cloud infrastructure on VMware and Red Hat OpenShift platforms.

I thrive in Agile/Scrum environments and love collaborating with cross-functional teams to ensure product excellence from day one. 🚀
