Objective:

C++ software development position with opportunities for growth of technical expertise.

Employment History:

• Debugged and repaired Java GUI and C/C++ server code for financial trading & order-routing system.

• Refactored Java GUI code, disentangling advertisement functionality from the IOI functionality.

• Designed, implemented, and debugged type-safe data-backed list & combobox GUI components, using Swing and Java generics.

• Enhanced, tested, and deployed Auto-Upgrader GUI and backend component.  Took ownership of unforseen external  requirements, working with other departments on system modifications required to support the Auto-Upgrader.

• Designed, developed, and implemented a performance-testing infrastructure in Perl and shell-scripts.

• Technologies:

  • Java, C/C++, SQL, stored procedures, Perl, shell-script

  • Swing, Eclipse, CVS, Sybase, FIX protocol, Linux, Windows XP

• Enhanced existing and implemented new feed-handlers for market-data sources.

• Refactored the entire market-data feed codebase to use NASDAQ's new symbology internally.  Designed, developed, and tested new high-speed conversion functions to translate other data feeds' symbology to NASDAQ's.

• Implemented and tested performance enhancements to core feed-handler C++ code.

• Designed, developed, tested, and deployed an integration-testing framework for Fidessa's market-data feeds (the “ticker-plant”), using randomly-generated simulated data.

• Expeditiously acquired understanding of in-house order routing system to deploy FIX line-handlers establishing connectivity between 3 sell-side institutions and a new customer.  Implemented new features for these connections to assure FIX conformance.

• Implemented numerous customer-requested modifications to the trading platform, both the GUI and the server-side (OMAR, CTAC, IMAR, FDA).

• Successfully merged out of date in-situ client-customizations with latest codebase, under challenging schedule to meet SEC-mandated deadline.

• Technologies:      C++, TCL, in-house scripting/IMDB language,  shell-script,  Perforce, FIX protocol

• Designed and implemented, in C++, a suite of data-integrity test programs for financial data processor. Created nondeterministic simulated data feed to validate computed quantities. Automated operation using Unix shell scripts.

• Designed, implemented and documented, a suite of automated analysis and test libraries and tools, in Perl, for an XML financial data product.

• Assisted table schema design for the MySQL backend storing a complete reorganization and normalization of all financial data fields transmitted by ComStock's TickerPlant. Implemented prototype SQL queries for future use.

• Introduced C++ template metaprogramming and compile-time polymorphism techniques to coworkers.

• Technologies:      C++, Perl, MySQL, sockets, XML, shell-script, doxygen, Linux.

• Implemented and debugged persistent search daemon, in C/C++, for propagating changes from a central iPlanet LDAP server to downstream servers.

• Developed Java application (and unit tests) to rotate a live SiteMinder log file, parse the contents, and store the data in an Oracle database.

• Assisted customer with deployment of SDG's in-house web performance monitoring tool. Initiated enhancements to the monitoring tool, employing research-grade statistical methods for data analysis.

• Enhanced web-based J2EE application for modifying an enterprise database of employee photo images.

• Technologies:

  • C++, Java, SQL, stored procedures

  • Oracle, JDBC, iPlanet LDAP, SiteMinder, J2EE

• Developed and deployed COM+ middleware components, in C++, for internal web-based  workflow application.

• Improved team productivity by aggressively acquiring working fluency in Transact-SQL over two weeks, in order to contribute to writing and debugging of stored procedures.

• Received management commendation for concisely and clearly documenting the installation process for the project, in a fashion useful to both developers and desktop support.

• Technologies:

  • C++, SQL, stored procedures

  • Visual Studio, ODBC, COM+, SQL Server (MS and Sybase), doxygen, LDAP

• Designed, developed, and debugged core components, in C++, for SNMP management library created independently from existing implementations.

• Designed and implemented novel nondeterministic unit tests for C++ applications and core libraries.

• Developed, documented, and tested core library (in C++/MODEL/ASL) used to build compatibility applications.

• Enhanced and maintained HP OpenView/Tivoli NetView compatibility modules (in ASL/MODEL/C++).

• Technologies:

  • C/C++, 2 in-house languages, shell-script, TCL, Perl

  • Solaris, HPUX, AIX, Windows NT

  • Multithreading, sockets, Lex/Yacc, CORBA, SNMP, Doc++/Doxygen, Purify, Quantify.
