Lead Developer Dave Ramsey Franklin, TN,
  • Architected and implemented the firm's trading API.
  • It was written in C++, and supported connections to multiple exchange endpoints.
  • It was responsible for order/position management, routing, and receipt of quote data.
  • The API also utilized ACE and Boost libraries for common tasks such as event handling, managing threads, synchronization and socket communication.
  • Was designed to minimize dependencies on 3rd party APIs, making migration to different vendors transparent to client applications.
  • It is currently being used in all new client applications.
  • Led design and was involved in implementation of a generic n-legged spreading engine.
  • Written in C++, it was built on top of the firm's API, and had an attached C# GUI as the front-end.
  • Also involved in ongoing enhancements per trader requests.
  • The engine has been utilized for trading in CME Eurodollar futures/spreads, equity index futures, eCBOT treasuries and grains, and the market-making program for Eurodollar packs and bundles to realize commission rebates.
  • Managed the department's migration from CME MDP to FIX/FAST, using Wombat API as the quote vendor.
  • Involved in installation and configuration of the Wombat Linux servers, and implemented the in-house price feeds using Wombat's MAMDA API.
  • Led the effort for the technology side of an equity pairs trading system.
  • Involved in the design and first pass implementation, which used Sterling API and Excel/VBA as the trading platform.
  • Managed the daily tasks of a group of 3 developers.
  • Determined project prioritization, resource allocation, scheduling, and requirements gathering for new systems.
  • Specified coding standards and led code reviews to improve software quality.
  • Also managed the continuous interaction with traders regarding new features and ideas for trades.
  • Managed design and development of a front-end used for manual trading.
  • The application was written in C#, and provided screens for order placement, book management, position management, and viewing of market data.
  • It also made use of a .NET version of the firm's API.
  • Was implemented in order to cut costs and overhead by removing the need for 3rd party front-ends.
  • Tracked down performance bottlenecks in the firm's API and middleware libraries, resulting in recommendations on improving order transaction latency by 1-2 ms.
  • Used Intel Threading Building Blocks (TBB) as the debugging tool.
  • Implemented a basket trading system for a floor trade in Excel VBA.
  • The spreadsheet used Sterling's ActiveX API and traded approximately 35 - 40 stocks.
08/2003 to 07/2006
Trading Systems Analyst Belvedere Trading New York, NY,
  • Working with a senior trader, implemented a Eurodollar spread trade in Excel.
  • The system used VBA and TT XTAPI to quote various Eurodollar futures and spread markets on the CME.
  • Once filled, the system performed simple hedging.
  • Designed, developed, and maintained an order routing framework, which was used to create the firm's trading gateways to TT, eCBOT, CME, Eurex, EurexUS, eSpeed, BrokerTec, Hotspot, INET, and Arca.
  • All gateways were written in C++ and managed orders from multiple gray box trading clients.
  • A proprietary database library was used for order management, allowing for high speed transaction processing and persistence.
  • Also involved in ongoing trader support and debugging of system issues.
  • The direct to market gateways replaced the ongoing monthly cost of various 3rd party systems, such as GL and Portware, and improved transaction latency by removing extraneous server hops.
  • Designed, developed and maintained a market data framework, which was used to create the firm's feed handlers.
  • All feeds were implemented in C++ and provided market data from eCBOT, CME, Eurex, EurexUS, eSpeed, BrokerTec, Garban, Hotspot, TT, and INET.
  • The system distributed data over IP multicast.
  • Also developed a C# RTD component that allowed traders to view prices in Excel.
  • Involved in development and maintenance of the middleware library used to route messages through the infrastructure.
  • Components were developed in C++ and communicated using text and serialized object messages over TCP connections.
  • The library also included wrappers for OS specific objects, such as threads, locking mechanisms, files, and sockets.
  • Developed an eSpeed smart order router.
  • The component received orders from client applications and sent them to multiple eSpeed API connections using a round robin algorithm.
  • Was implemented in order to avoid the eSpeed API limitation of having 1 order per price level.
  • Developed test components for the exchange gateway servers and client software.
  • Using the .NET framework, implemented a GUI used for order placement and book management.
  • Used as the front-end tool for certifying direct to market gateways with exchanges, allowing for a more efficient test cycle.
