    Bloomberg Financial Markets LP, New York City
      Technical Lead/Senior Software Developer — (3 direct reports)                                        03/2000--07/2006
      Technical Environment
      C++, perl, MySQL, Java, C
    • Research the concepts and Designed unique system to monitor latency and integrity of market data. Created the prototype that worked on a generic market data format. The prototype method finds a time-series match between the data stream from the source of market data and from the client, by maximizing the cross-correlation value concurrently calculating integrity and latency (Patent application pending).
    • Conducted Vendor/Product research of Search Technologies as a part of participation in a working panel of company wide experts.
    • Assumed the project manager role to lead implementation efforts by other groups, integration, testing and rollout of beta version of the market data monitor based on the prototype design described above. Productized the monitor via integrated Enterprise Management System (EMS) framework on the basis of the third party product, HP Openview. EMS is a framework to manage Bloomberg applications.
    • Research concept of generic correlation of disparate EMS alarms coming from different applications to automate problem finding system. Implemented mechanism to route all EMS events to HP Openview system. The mechanism provides enhanced event categorization as well as filtering and rate suppression capabilities to the console room Operations. The legacy system used to rely on many operators noticing a reoccurring alarm in a scrolling stream of alarms in a window. The new system supplies a ‘manage-by-exception’ capability to an operator thus drastically improving problem detection ability.
    • Created an application for automatic scheduling and handling of batch system commands, for network troubleshooting (backend written in C++, front end HTML). The library is used by other developers in R&D to troubleshoot network problems replacing the direct access granted to Tech. Support, thus closing a potential security hole.
    • Designed and developed multithreaded (consumer/producer) real-time high-performance (500 Kbytes/sec) CORBA based middleware (written in C++). It served as a backend metrics collection system for automated outage detection system described below.
    • Conducted research, collected statistics and analyzed the patterns of network outages. Researched, designed and developed the prototype for correlation analysis of network outages. The automated outage detection system determines the most likely point of failure in the network before customers could take a notice. This analysis provided vast capabilities for real-time troubleshooting network failures. Researched and developed the model of background noise levels present in measurements of network outages. Used the model to implement noise from signal subtraction. Transferred the prototype design to other group members for the implementation. Participate in implementation process.
    • Created a tool for handling and scheduling automated batch commands (ping, trace route)
    • Designed and developed an allocation algorithm for load balancing of Bloomberg clients amongst backend machines and gateway servers. Implemented (perl cgi) and turned over to Operations an application based on the algorithm. It is widely used by operations and monitored as a critical.
    • Developed complete (backend C++ and front end Java/JavaScript) application for troubleshooting and monitoring voice-over-IP communications over Intranet
    • Development of a data collection system (C++) that probes Bloomberg Internet and Intranet for network metrics (IP, retransmition rates, network delays).
    • Optimized and normalized the proprietary database based on UNIX indexed hash tables (C++) used for storing metrics for near-real time troubleshooting. Optimized the database to be able to insert up to 10,000 records per second. The resulting system was unique to the R&D department (perhaps in the industry) in efficiency and speed
    • Implementation of a front end Java client to display analysis of network performance metrics in a form of graphs and/or tables, grable (Java, Javascript and fastcgi). It had been also used for logging the usage of financial functions (stocks, bonds and indexes) on Bloomberg application.
    • Expanded the data collection system from being solely proprietary database to the Open Source MySQL database on Linux. This greatly increased our flexibility for tuning and optimization of the data collection to increase its performance up to 3,000 inserts per second. The system probes Bloomberg Internet and Intranet for network metrics.
    • Developed and maintained Unix C++/STL development libraries for network name lookups, IP resolution, address translation and API for CORBA (omniORB 3.0) widely used by back end server applications
    • Created an cgi perl-based point and click user interface for the 'intruder alert' web based tool. It had been used by the security team as a trigger mechanism to start probing our network for security breaches.
