About

Cybersecurity professional currently working in incident response and digital forensics. I have prior experience specializing in penetration testing, red teaming and offensive security. My professional journey in cybersecurity commenced in 2020 as a Security Analyst, delivering robust security solutions through penetration testing and cyber risk assessments for clients, worked in multiple projects across both red and blue team roles. I then specialized in a red team role at Synopsys as a Security consultant where I was heavily involved in Offensive Security and Penetration testing in network and application security and hold several certifications like the OSCP, OSWP and CRTP etc. After the completion of my masters degree from DePaul University, I pivoted into the DFIR space and now work on active incidents and forensic projects at Charles River Associates. Outside of work, I do side quests in Hardware, OT and automotive security, engage in Capture the Flag (CTF) competitions and like to vibe code and build AI solutions.
