Faizal Hasanwala is a software engineer with nine years' experience building reliable, user-focused features for Excel and other large-scale web applications. At Microsoft he improved Excel Online reliability, added support for legacy and password-protected files, and revamped Version History and formatting experiences for desktop and web. He blends a strong CSE foundation from IIT Roorkee with hands-on web application security practice, routinely hunting vulnerabilities through Synack bug bounties. Now at Google, he continues to apply data-driven approaches to improve product robustness and collaboration workflows. Faizal is as comfortable shipping client-side UX improvements as he is diagnosing backend reliability issues, and he brings a proven track record of lifting service SLAs while preserving usability. An underrated strength is his ability to translate security insights into practical product fixes that reduce real-world attack surface without harming user experience.
