Fixed the product installer to address issues reported by users as well as those introduced by Windows Vista UAC (user account control). Made the product installable under variety of environments, Windows versions and access rights. Analyzed and fixed application crashes using crash dumps reported to Winqual by users.

Norton products were redesigned from scratch due to constant complaints about bloated size and performance. Solely responsible for redesign and implementation of precondition engine in LiveUpdate. A small C-like compiler that allows update publishers to write small scripts. Performance and binary size were major constraints. Created a comprehensive unit test suite for the component, reducing the reported bug count to less than 10.

Textminer is a tool used internally by Microsoft to classify a large amount of incoming emails. Designed a fail-safe mechanism. If the application crashed, it would come back as it was when restarted. Developed a slick new user interface to make it more easily usable. Received an MVP award at Infosys for work on this project.

Finance IT suite of applications is a large collection of software used by Microsoft to manage treasury, receipts, billing, investments, etc. There were 20+ applications written in C#, VB.net, ASP.net, SQL, etc. I worked on many of them, often simultaneously, for bug fixing and feature development. My team won Zero Defect award for one of the deliveries on this project.
