Developing Erlang-based solution for low latency trading surveillance to prevent insider trading in broker-dealer and market-maker environment for exchange traded securities.Solution stack: Erlang, C++, Python, MySQL..

Developing application framework for processing very large data arrays of historical tick data on a large cluster of commodity PC. The Erlang­-based system will facilitate pattern recognition analysis of historical tick data time series by parallelizing computations for different time intervals and different markets. The system will serve as a data distribution, load balancing and control center for the cluster nodes providing high degree of fault­tolerance by using sophisticated error recovery model.Developing Erlang-based FIX session level protocol gateway and messaging solutions.Securities Exchange simulation for stress and regression testing of exchange order gateways.Latency monitoring framework with high resolution timestamps.
