About Me

I am an Engineering Manager in Cisco's Security Business Group (SBG) on the Firepower product suite. I manage a team of developers working on software for Cisco's Security Business Group on the Firepower suite, focused on Identity & Access Management, Network Configuration Management, REST API Framework, and Cloud Services Integration.


I have seven years of experience working as a full-time employee in the software development industry. Additionally, I have seven years of experience working in various academic and non-academic research organizations doing Cybersecurity research.


I have led software delivery in Identity & Access Management and Security Containerization solutions. I have experience working on various areas of Cybersecurity software starting from the development and delivery of solutions like Single Sign-On, Multi-Factor Authentication, External Authentication to fixing security vulnerabilities disclosed via MITRE Corporation's CVEs, implementing firewall technologies using modern cloud computing infrastructures like Docker and Kubernetes.


I am interested in Engineering/Product Management work. Due to my research and industry experience, I would best fit in a Cybersecurity domain, but I am open to working in other domains as well.


I completed my Ph.D. in Computer Science from the University of Maryland, Baltimore County in 2017. My dissertation topic was "Context-dependent privacy and security management on mobile devices". During this time I did research internships at Samsung, Apple, and Symantec.


From 2007 to 2010, I worked as a Software Engineer performing design and development of application programming interfaces to be used by client systems to manage backend databases, with Tata Consultancy Services, India. I graduated in 2007 with a Bachelor of Engineering in Information Technology with honors from Jadavpur University, India.
