GEORGE A. LEWIS
Nutley, NJ 07110
*****@*******.***
Objective: A development position using C++ or C#, possibly using design tools such as Rhapsody or Rational Rose in a stable firm in New Jersey, appropriate for a senior level professional working in the real-time software development field since 1986. Experience: L3Harris, Inc., Clifton, New Jersey, 2010-2023: Lead Engineer Accomplishment Overview: Since 2010, I have worked on the GPS III program:
● Maintained test system software on a Windows platform using C++, C# and SQL, resolving bugs and adding enhancements.
● Developed internal company website using C# and SQL to track product problem reports.
● Debugged scripts written with in-house scripting language, using a C# test engine on a Windows platform, getting them to run for customer sign-off on deliverables.
● Developed C# unit test code on Windows for exercising software modules and presented to customer in formal reviews.
● Developed XML representation of GPS navigation messages using C++ on a Windows platform.
● Converted C code for state vector processing in Unix into C++ classes in Windows, that I then reverse engineered into design diagrams using Rhapsody. Maquet, Inc., Mahwah, New Jersey, 2008-2009: Software Consultant Accomplishment Overview: During 2008-2009, I worked as a software consultant for a major medical device company developing the next version of their life saving medical device, using the Rhapsody modeling tool to develop C++ classes to run on a real time processor using the Green Hills operating system. The final product will be a complete rewrite of their existing product functionality, including software and hardware enhancements.
Invidi Technologies, Princeton, New Jersey, 2004-2008: Senior Software Developer Accomplishment Overview: For almost four years, as lead designer at a small start-up company, I used the Rational Rose modeling tool to design an entire system of C++ classes that seamlessly run on several platforms, including Windows, Solaris, and various embedded set top box platforms from Motorola and Scientific Atlanta. The final working product is a system where data is exchanged between real-time embedded applications running on cable set top boxes and a Solaris system to classify viewer audiences in real-time, and to subsequently target audiences with viewer specific television advertisements in real-time.
● Utilized Rational Rose design tool in order to create accurate designs and flexible code – since the application required passing of data between different platforms using different compilers and different processor byte ordering schemes, I modeled classes with methods that allow the data shared amongst the various embedded and non-embedded platforms to appear identical on each platform, thus allowing major code reuse across many environments and minimizing software maintenance.
● Instructed fellow staff members in the use of C++ and Rational Rose design tool
– since most of the team had never used the design tool, I taught the team how to use the tool, which enabled them to quickly generate both code and design diagrams. Since the team also never used C++ in embedded applications, I showed them how to effectively use C++ to address the embedded programming needs and limitations.
● Wrapped real-time constructs such as semaphores, mutexes, etc. in C++ classes for cleaner and easier usage in application code.
● Created testing tools to exercise software and benchmark its performance – using Microsoft Visual Studio, I created several test harness projects where a developer could unit test and benchmark the classes I created before running them in the embedded set top box environment, which allowed for code to be debugged and benchmarked more easily.
● Maintained several dozen make files responsible for compiling and linking of code on several embedded and non-embedded environments, including Cygwin & Cygnus (using GNU & Metrowerks compiler), Solaris and Linux (using both GNU & Microtec compilers).
● Designed and implemented user interface in HTML to monitor and control the system, including the ability to monitor and configure embedded set top box applications via a web browser.
Reuters/Bridge/Telerate, New York City, New York, 1992-2004: Software Designer Accomplishment Overview: Over the course of more than eleven years, I was a major contributor in a team effort of maintenance, redesign, and replication of real-time application functionality for existing antiquated Concurrent OS/32 systems written in Assembler and Pascal onto the Hewlett-Packard Unix 10.20 environment using C++ generated by the Rational Rose modeling tool, and then in turn I ported this same real-time C++ code to both the VMS and Windows platforms. The main purpose of this application is to distribute real-time financial data over a network while additionally performing value added real-time processing on the real-time data passing through the network.
● Utilized Rational Rose design tool to create accurate designs and flexible code.
● Instructed fellow staff members in the use of C++ and Rational Rose design tool.
● Created testing tools to exercise software and benchmark its performance.
● Maintained several dozen make files responsible for compiling and linking of code on Unix, VMS, and Windows platforms.
●
● Fine tuned software and made performance enhancements to improve real-time processing when necessary, including optimization of stack call parameters, inlining of code, and development of a class to buffer disk I/O.
● Developed TCP/IP client/server classes using sockets to allow computers to exchange critical data in real-time over the company’s intranet.
● Designed logging facility so that real-time transaction processing can be recorded for future playback, analysis, and debugging.
● Implemented enhancements to real-time Assembler and Pascal software modules on Concurrent OS/32 platform.
● Supported Operations personnel in troubleshooting problems on a 24 hour basis. Cantor Fitzgerald Securities, New York City, New York, 1989-1992: Programmer/Analyst Accomplishment Overview: For almost four years, I was a lead programmer in the maintenance development, and support of critical 24 hour online real-time trading systems for various types of government securities.
● Developed and maintained Assembler, Cobol, Fortran, and Pascal program modules of a real-time online trading system, including interfaces to DMS/32 databases, along with interfaces to user terminals and printer networks.
● Generated Concurrent OS/32 system modifications to match system hardware changes.
● Authored operations manual to ensure reliable 24 hour system uptime.
● Designed and implemented communications software and RS232 wiring to allow micro to mainframe and mainframe to mainframe data transfers in real-time. Applied Computer Technology, Mountainside, New Jersey, 1988: Programmer/Analyst Accomplishment Overview: For one year, I developed a system to store and search mortgage information in real-time in order to facilitate searches by users, which required database programming and ANSI user terminal interface and graphics programming.
● Implemented desired user functionality using Pascal and a Concurrent DMS/32 database.
● Analyzed software modules to improve real-time efficiency and error handling to insure a quality software product.
● Installed hardware on Concurrent OS/32 computer models 3212 and 3230, and IBM compatible personal computers to improve performance.
● Trained clients in use of software and hardware and authored formal user manuals to foster client acceptance of software product.
● Authored 130 page programmer's documentation of Pascal compiler procedures and functions to aid programming staff.
