​I am a currently a Principal Software Engineer/Architect at Wabtec Digital Electronics.

Architect, code and test the TCOS (Train Control Office Systems) core that provides classes and methods in Java, C, C++ and C# for TCP/IP, AMQP (ITCM) and Class D message transport/processing, real-time database persistence (memory mapped random access files), memory based pipes for inter-process communication, real-time event processing, security (AES/RSA), file operations, message validity checking (CRC/HMAC/MD5), message encoding/decoding (AMQP/EMP/Class D), thread management/pooling and logging that are used within Wabtec products.

Architect, code and test major parts of the Next Generation MDM (Mobile Device Manager) in Java that is responsible for synchronizing the software, configuration, track information and log files with the back office and the TMC (Train Management Computer) for positive train control (PTC). The TMC communicates to the back office through Wi-Fi, Satellite, 220 MHz radio or cellular networks as required based on the train location.

When I was a Principal Engineer for ARINC (Aeronautical Radio Inc) and Rockwell Collins, I wrote major parts of the train control system for Amtrak while working in Wilmington, Delaware. This is a SCADA (Supervisory Control and Data Acquisition) system that controls all train movement and power distribution for the northeast corridor (NEC) using Java, C, C++ and 80x86 assembly language.

I am the architect of the following US patents:

• US8281004B2 (Granted) - Multi-threaded method and system for automated remote submission of jobs to mainframe and Unix systems from the Windows™ platform.
• US20230143035A1 (Pending) - Multi-threaded vehicle communication system and method.
