About

Passionate about enhancing collaboration confidence in Microsoft Excel, I am currently working to improve the Version History experience in Excel. I hold a Bachelor's degree in Computer Science and Engineering from the Indian Institute of Technology Roorkee, where my interest in Web Application Security took root and flourished. Leveraging the security skills honed during my time at IIT Roorkee, I actively contribute to maintaining the security of Microsoft Excel Online. In addition, I actively participate in various bug bounty programs on Synack, continuously seeking out vulnerabilities to enhance my security skills.
