About

Throughout my career, I have consistently showcased my prowess as a seasoned Cyber Security professional, driven by an unwavering passion to harness my deep-seated comprehension of Cybersecurity for a constructive influence. In my current capacity as a SOC Analyst at Deloitte, I shoulder the critical responsibilities of deftly managing incidents and furnishing effective client solutions. My role entails harnessing state-of-the-art technologies including Splunk, Chronicle, Crowd Strike, and CarbonBlack, as well as adeptly navigating intrusion detection systems. Furthermore, I assist clients in proficiently overseeing their server-oriented remedies through the adept utilization of Xpanse and Prisma Cloud. My proficiency extends to encompass the adept employment of user behavior analytics tools like Exabeam and Symantec DLP, which augment my ability to identify potential security breaches and engage in comprehensive OSINT investigations to unearth any suspicious activities. Outside the precincts of my professional sphere, I derive immense gratification from indulging in poetry, relishing musical interludes, and embarking on immersive binge-watching sessions. My personal ethos is deeply intertwined with championing the cause of "zero food waste," a commitment that underscores my firm belief in contributing positively to the community that surrounds me. A ceaseless thirst for knowledge and growth propels my quest for fresh avenues of learning. Eager to foster connections with fellow professionals in my domain, I approach each interaction with excitement and an open mind. Please don't hesitate to reach out to me; I welcome the opportunity to engage in meaningful discussions and collaborations.
