• Designed end to end multi-threaded low latency application for handling speedy incoming multicast traffic for exchanges NSE, BSE, MCX and EUREX with no packet drops using hardware acceleration technology of onload. Implemented recovery mechanisms for the various exchanges in case of packet drops in case of network jitter. The application was designed in two modes : socket mode and efvi (ethernet virtual interfacing for acceleration - bypassing the entire kernel stack) mode.
• Captured spanned ethernet layer frames of multiple TCP connections with hardware timestamping using onload hardware acceleration and reconstructed TCP streams with gap detection and handling. Used google protobuf compiler protoc to dump the constructed TCP data and easily port into databases and can be used cross platforms.
• Worked on enhancing features of Market Simulator to create test environment for trading strategies on historical data. Optimised the path of injected simulated data between data supplier module and the Sim Exchange.
