• Developing low latency software for a high frequency trading company.
• Performance Optimisations
• Focus on performance — reduce memory footprint of the system to allow cached data and
• reduce churning of memory out of cache, reorganised memory layout to keep frequently
• accessed data in the same cache line.
• Redesign of trading servers to allow faster sending of data using different strategies.
• Study and support for network card features for improving end-to-end latency and
• preventing packet drops on a machine.
• Design of system to capture the data for simulation and to measure the end to end (on-wire)
• latency of the system.
• Study and understanding of cache and multi-core architecture, NUMA memory for system
• layout and performance.
• Software Architecture & Design
• Design and development of software for exchanges - OSE, EUREX, MCX, BSE, NSE and
• handling continuous updates to the software as per new exchange API releases.
• Support for common apis for different exchanges to simplify strategy logic and to manage
• order placement data structures in the same place.
• Standardization of code using templates to avoid repeated code and separation of exchange
• dependent code from exchange independent logic.
• Reverse engineering of transaction based exchange protocol to allow data transfer using methods that are in line with current system.
• End-to-end development of system to allow processing of new securities during trading hours without restart.

• Developed a test setup to experiment with UDP network protocol in production and development environment for the service.
• The service used to run over TCP and does not scale well over UDP. troubleshooted and fixed memory leaks in the system for the UDP code paths.

• Built a block level system that integrated cloud based storage services like Amazon S3 with disk storage. The system supported any file system to run over it.
• The system provides speeds close to hard disk (~10ms) for cached data, and ensured crash recovery at reasonable performance of the system.

• Content Distribution in the Internet & Rural Areas. Designed an intelligent network architecture that is content centric for mobile users. The system was an overlay network which provides a set of services to content providers for caching and replicating popular content bringing then closer to the edges.
• Developed a java based prototype of the architecture with allows asynchronous (disconnection tolerant) data transfer for mobile users using opportunistic communication. The asynchrony was achieved by using RMI based fast control channel and socket/DTN based data channel.
• The prototype was used by a bunch of projects at IITD involved in study of routing protocols for rural networks, integration with online social networks etc.

• Design and Development of features in Shopping cart services and Amazon’s Indigenous service Dynamo. These services maintain strict latency limits for very high volume of traffic that the website is subjected to.
• Took complete ownership of mailing service which is responsible for sending email to customers under various use cases. Single handedly undertook design, development of project initiative and operations/contacts for the service.
• Design of Test Framework using JUnit.

• Evaluation of Space Saving Opportunity with the extension of Snapshots to NetApp’s Space Saving De-Duplication Technology.
• Evaluation of Worthiness of Variable De-Duplication to the existing technology. Developed a sliding Window Algorithm for variable block size and drastic improvements we found in repetitive data sets.
• The tool was made to run on 1TB Data. Was offered a pre -placement offer based on my work.
