Started on the RDFD Core framework development team. The RDFD product supports High Frequence Trading platforms by normalizing exchange data into the Reuters Data Format. The system can handle tens of thousands of exchange messages per second with a maximum of 15 millisecond end-to-end latency. The system started on Windows and was ported to Linux maintaining the same latency requirements. In addition to the porting and refactoring parts of the libraries, I rewrote the build system to simplify our use of CMake and Jenkins build servers when we moved to Linux. I also provide user and application support on one of the Linux development servers used by programmers in North America. Support work as part of the framework team includes working directly with programmers in North America, Great Britain, and China. Support includes regular teleconference meetings with those development teams to help them use the libraries. Environment/Tools: GCC, GDB, Linux, MS Visual Studio, C++, Windows XP, Boost Libraries, OOD, OOP, Subversion, Git, Bash
FlightSafety makes flight simulators for training airplane pilots. I joined the tools group that develops a variety of utilities that are both delivered to customers and used internally. My first assignment was to port existing programs from Unix/g++ to Windows using MS Visual Studio v7 while maintaining source code compatibility with both platforms. I also worked on software development guidelines to be used in a Department of Defense contract. These included a coding guidelines and peer review processes that met the requirements for an ISO9000 compliant project.
Environment/Tools: MS Visual Studio, C++, Windows XP, GNU C/C++, Boost Libraries, OOD, OOP, CVS, Rational Purify.
Returned to the Digital Communications System project that I had worked on when I was at Boeing the first time. This system handles messages used to coordinate combat action between F/A-18 fighter jets and other aircraft or ground forces. This phase of the project involved adding new features and new message types. My job included writing new code, enhancing existing code and writing and implementing test plans to cover unit testing, system tests, regression test and validate new code.
Environment/Tools: C++, Windows 2000, BSD Sockets, MS WinSock Sockets, OOD, OOP, Rational ClearCase, Rational ClearQuest, CodeWizard.
Designed and implemented an automated source code generation tool for use in a unmanned weapon systems software development. The software was designed as a filter framework for which plugins were written to support each type of code to be generated. The initial toolset converted interface and design specifications from a tool used by system designers into Ada95 source code. This was a two person project team where I played the design lead. (Boeing)
Environment/Tools: C#, .NET, Windows 2000, ClearCase
Worked on a major upgrade and daily maintenance of a data warehouse system. (MasterCard)I joined the conversion project about half-way through requiring me to quickly become familiar enough with both the old and new systems. Most of the work was updating existing programs for loading and extracting data and generating reports. Detailed regression testing was required to verify that updated report programs produced the same output as on the old system. The upgrade consisted of a completely new database and a ten-fold increase in the number of data items stored. Wrote software to filter XML data before sending it to customers. Made customer-specific modifications to the data warehouse applications to handle special processing needs. Requests for these changes typically arrived within one or two days of when they were needed and had to be designed, coded and tested quickly. Modified existing report programs written in perl. Wrote ksh scripts to drive the report programs.
Environment/Tools: C++, Unix, Sun Solaris, Windows 2000, XML, Oracle, Pro*C, Ksh, Perl
Responsible for maintaining code written in C and C++. (Southwestern Bell)Maintain and enhance a suite of C++ programs that automates error corrections on customer orders. Assisted in the design of a version control and release management strategy for a project team ranging from Illinois to California. Converted a set of old K&R C programs to ISO/ANSI C and replaced Unisys tape I/O with Unix disk I/O as part of the conversion.
Environment/Tools: C++, C, Unix, Sun Solaris, Windows NT, Sun Forte`, Unisys OPE (Unix hosted on a Unisys mainframe)
Developed a network using Jabber to emulate radio communications between airplanes and ground systems. The system connected multiple desktop computers to emulate different airplanes in a fighter group. (Boeing)
Worked on the Digital Communications System used by F/A-18 fighter jets. The system managed communications between airplanes and the ground. Part of my job was mentoring several other programmers who were new to C++ and Object-Oriented design. This usually involved guiding subsystem redesigns where the original designs had not aged gracefully. (Boeing)
Environment/Tools: C++, Solaris, Windows NT, VxWorks, Jabber, XML, OOP, OOD, Rational Rose, Purify, ClearCase, CodeWizard.
I participated in the design and development of a network load balancing system to work with Cisco routers. Our software probed network services to measure the availability of each system in a server farm. (Impact Technologies)
Created a multi-threaded XML database. The database included an API that allowed local programs to make real-time updates and a SOAP API for use by remote applications. The system was written in standard C++ to provide portability between Windows NT/2000 and Solaris. (Impact Technologies)
Environment/Tools: C++, Windows 2000, XML, Solaris, SOAP, BSD Sockets, MS WinSock Sockets, HTTP/HTPS (secure sockets), OOD, OOP.
Developed a Unix server program to calculate charges for client programs running on Windows. The program is used when customers redeem coupon-style certificates or points. A variety of business rules are applied based on the requested merchandise and account. The server also charges one or more customer credit cards to complete the transaction. (MasterCard)
Converted Oracle stored procedures to external programs to improve maintainability and add new features. (MasterCard)
Environment/Tools: C++, Solaris, DBTools.h++, Oracle, SQL, Paylinx, Unix Shell, PVCS, OOD, OOP.
Worked on an NT service to enhance a dial-up network used by all wholesalers throughout the United States. Replaced a MAPI based system with one that used FTP for moving data. The new system improved network efficiency by more than 90% and proved to be far more reliable during a period when usage increased ten-fold. (Anheuser-Busch)
Converted from MS Access databases to Oracle for server side configuration and network profiling data. The migration included a complete redesign of the database tables to incorporate relational techniques. The system is hosted on Microsoft Windows NT servers that exchange data with IBM S/390 and SP2 systems on the server-side. (Anheuser-Busch)
