PROFESSIONAL EXPERIENCE

Confidential, St. Louis, MO

Programmer Analyst

Responsibilities:

• Built feed handler for 15 channels of CME FIX & FAST protocol Level 2 feed: channels 7 through 14, 31, 32, 111, 113, 115, 118, and 120. Each channel had unique characteristics, necessitating utilization of existing CME documentation, and extensive trial and error testing for each build.
• Implemented a parser for the FIX protocol to convert decoded exchange messages to internal Confidential structures and data types to ultimately populate the outgoing messages.
• Developed, certified and maintained CME Globex order and price books based on Fix 4.2, which comprised multiple modules like the FIX Engine, Book Calculations, customized Data structure(list/tree) library in C/C++, C#.Net, multi-threading, sockets and Oracle 9i for trading.
• Developed and tested the NYSE ARCA Complex options, OPRA and TSX L2 market data feed handlers.
• Tested the messages and the regular and implied price books, and ensured they were correct, including: data, system, and soak testing, debugging, QA support, deployment and post-deployment support.
• Utilized valgrind, gdb and in-house tools to maximally optimize memory usage and performance, for effective handling of high data volume from the different market feeds running on a single Ticker Plant. Did extensive performance testing, code optimization, tried various feed handler deployment configuration to minimize latency and maximize performance.
• Production support on different feed handlers: Level 1 on CME FIX/FAST L2 feed handler; Level 2 support on TSX L2, CTS and other feed handlers used by high-frequency algorithmic traders.
• Implemented persistent in-memory security ID-security definition maps using struct arrays and stl::map and also stored them in back-up files for feed recovery.
• Developed the cascaded feed handler to allow fanning out of feeds to allow multiple downstream clients. Used UDP and TCP/IP to develop this feed handler.
• Refactored and debugged the TSX L2 feed handler including the STAMP parser, and took it through the QA phase.
• Added MOC imbalance message processing functions to CTS, NYSEALERTS, and other feed handlers, and implemented a price/price format calculation function common to all channels.
• Added ticker plant monitoring support and Oracle 8i interface to Zenoss.

Programmer Analyst

Responsibilities:

• Participated in all aspects of the software development life cycle from inception to completion, including initial design and architecture meetings. Used Object Oriented Analysis and Design for product design to design and build the low latency market data feed handler library to enable development of lower latency, higher throughput feed handlers.
• Implemented the FIX protocol parser to enable parsing of FIX messages streamed from various exchanges. Also integrated an in-house FAST protocol decoder with the FIX parser to enable handling of FIX/FAST encoded feeds.
• Participated in development of the NYSE feed handler on this platform as the verification handler for the new low latency market data feed handler library. Interfaced the library with TIBCO.
• Built Arbitration Handlers (Sequence, Hash, and Time) for the parallel input feeds received from the exchange and the UDP and TCP/IP-Input Handler for exchanges that provide UDP/TCP feeds.
• Improved system performance of the feed handler end-to-end and the feed handler library during development and QA.
• Provided Production Support on the feed handler library (Level 1) for NYSE feed handler used by high-frequency algorithmic traders.
• Used C#.Net for the GUI for the config and control modules.
• Served as Project Coordinator for four months: ensured project components were completed accurately and on schedule, participated in planning and status meetings, and reported to project manager.
• Assisted in development of a sample trading application to verify feeds developed on the feed handler platform. This included support for FIX and STAMP formatted messages.
• Assisted with unit/integration testing teams, configuration management, and documentation.
