1. Developed location tests to validate GNSS and geo-fence scenario. This will be shared with partners for bringing up new threshold location drivers2. Developed tests to validate WiFi crowdsourcing functionality and data contracts with Windows Phone services in Windows Phone 8.1. The data is used for providing better location and WiFi auto-connect functionality.3. Developed tests to automate connecting to top 100 networks reported by selfhost phones in Windows Phone 8.1 and used to quantify the quality of WiFi autoconnect feature by testing both cloud and client components4. Developed automation tests to validate enterprise WiFi policy and profile provisioning to ease connecting to enterprise networks without user intervention in Windows Phone 8.15. Tested Backup and roaming feature to make connecting to known WiFi networks on phone easier by roaming them securely from Windows PCs.

1. Developed test automation software to test WiFi miniport driver on Windows Phone 8 NT kernel. Used by hardware partners to bring up WiFi drivers2. Worked with hardware partners to provide tools and tests bringing up WiFi drivers for Windows Phone 8 for tethering support3. Tested tethering with cellular simulators for performance and stability to complete operator requirements of continuous 30 hour usage. This was useful to pass operator trials quickly for the new SoftAP/tethering that was built in Windows Phone 8.1

Master's in Computer Science and Engineering Department. Interested in embedded systems, operating systems and computer architecture Learning Based Thread Scheduler for SMT ProcessorsDesigned and evaluated a learning, thread work load based scheduler for SMT processors to optimize on total execution time. Achieved 2% increase on traditional ‘Icount’ algorithmOperating System Controlled Memory Bus EncryptionSoftware approach to protect the memory bus assuming minimal hardware support such as Cache line locking present in many processors.Dual-Core “Out of Order” Processor DesignDesigned and developed a dual core, snoopy-bus based, MESI protocol cache coherent out of order processor architecture using a re-order buffer and a retirement RAT. Best working Multicore assignment turned in for Introduction to Computer Architecture course. Automatic Thread Extraction of Decoupled threadsProposed and implemented a thread extraction algorithm to reduce synchronization costs to extract more loop-level parallelism
