EXPERIENCE

Confidential

Senior Software Engineer

Lead developer for design, development and maintenance of control software for a third generation high-speed Explosives Detection System used for screening checked baggage. Responsible for the effort to achieve scanner software reliability such that the scanner can proceed to 'final acceptance test' at the factory and TSA testing to allow the government to allow sales and installation of the scanner.

Developed a library to replace current flat-file based name/value pair flat files used for setting run-time parameters. All linux boxes on the scanner can access parameters via one MySQL database via this library instead of dozens of flat files. Implementation was in C/C .

Designed and developed an application to parse all system logs on a scanner to provide an analysis of the behavior of the system and provide a report as to system performance and any anomalies that had occurred during baggage scan as well. Implementation was in C .

Designed and developed a parsing application to monitor/analyze the current or historical output of one of the low-level subsystems DLC of this scanner. This DLC program communicated with 5 other subsystems via RS232 and logged its activity. This parsing application was used by factory personnel as well as field service to diagnose problems with this component by interpreting the output bitfields and translating to human-readable format. Implementation was in C .

Lead developer for design, development and maintenance of control software for an upgrade to a first generation Explosives Detection System used for screening checked baggage. Reason for the upgrade was that critical control hardware had gone end-of-life, crippling the ability for the company to sell more of these very popular scanners. Re-wrote current control software and migrated from a DOS-based 486 application to a Linux based multi-threaded solution. Implementation was written in C . This was a multi-process solution using shared-memory and sockets as interprocess communication.

Technical Consultant Contractor

WC Wealth Central

Worked with a team of consultants and Fidelity employees to develop and deploy an individual trading application Wealth Central . This application allows individual investment advisors to trade stocks on behalf of their clients and uses the Fidelity clearing back-end. This application was multi-tiered using C /.Net and Shockwave Flash for the presentation layer, C on the middle tier and Java for the servlets running on the Tomcat back-end server.

Senior Software Engineer

Lead developer responsible for design, development and maintenance of control software for a second generation Explosives Detection System used for screening checked baggage. Interfaced with the acceptance testing group at the company responsible for selling/integration testing of these scanners. Also travelled to the installation site airport to interface with the TSA and baggage handling system personnel in a four scanner pilot program. Implementation was a multi-process linux based solution written in C and C . Technologies include: multi-threading POSIX, MySQL, shared memory, named pipes.

Senior developer for implementation of a multi-threaded POSIX process responsible for interfacing with the baggage handling system for a carry-on baggage Explosives/Weapons Detections System. This consisted of a CIP Common Industrial Protocol enabled layer running on top of TCP/IP written in C communicating with a local PLC Programmable Logic Controller on the scanner. The local PLC is connected to a peer PLC that is controlled by the airport's baggage handling system.

Senior Software Engineer

Designed and developed a communications relay application Etherspine-RV gateway or ERVG in C which allowed RV Tibco based clients to communicate with the proprietary networking protocol.

Designed and developed a java front-end for the estool data analysis suite. This consisted of a java applet for the GUI and accessed estool via a servlet which remotely executed estool and sent the data back to the browser.

Maintained and enhanced a console based trading application used to input trading orders and is written in C and Tcl. Designed and developed a hardware neutral keyboard mapping scheme for trading application.

Ported data relay application from Unix to Linux. This application consisted of a server and client written in C sending data via TCP/IP sockets bridging data from/to proprietary network protocol and TCP network.
