Engineer in Microsoft's Hotmail scalable data backend.Service - Built high performance and scalable incoming e-mail serving tier using a lightweight data flow design instead of traditional multi-threaded approach. This maximized hardware utilization and lowered overall cost.Performance and Efficiency - Improved performance of the backend cluster with better queuing, locking and synchronization, detecting idle or aborted connections. This increased throughput by 25% and greatly reduced cluster sizes needed for peak traffic.Reliability - Improved availability of service by active load balancing of incoming traffic. This improved the success rate of incoming emails by over 50%

Bengaluru Area, India

Implemented a scalable gateway for high bandwidth data transfer between IBM mainframe clusters and new high-speed commercial printers. The goal was to manage and process a very high inflow of data and match it with the hardware capabilities.Built SCSI tape driver for proprietary tape hardware. Designed and implemented a new tape file system for efficient backup and restore.High performance file system for data spooling and sharing of data between different system architectures.
