• Lead architect to provide an F-16 simulator that integrated with Lockheed-Martin's F-16 MIMIC system. System provided continuous updates from a live F-16 which were then used to update a simulated F-16. The MIMIC system is used by the Air Force as a pilot training tool.

• Lead architect in simulator upgrades provided to the United States Air Force Test Pilot School. These simulators are used to evaluate incoming Test Pilot School candidates.

• Lead architect for development and integration of both and F-18 anf F-16 simulator in Boeing Seattle's test lab for the Boeing 737 AEW&C platform. Fighter cockpits worked in tandem with the AEW&C test bed sending and receiving Link-16 data messages and performing simulated assignments.

• Designed and developed a simulated radio subsystem to support Level 0 Link-16 simulation. The system supports the transmission and reception of simulated radio messages.

• Designed and developed a Level 0 Link-16 subsystem. This system supported the exchange of Link-16 messages between disparate entities within our simulation environment. Implemented the DIS component to allow for the Level 0 exchange of Link-16 messages between distributed simulations.

• Designed and implemented the ZedaSoft's DIS transfer of control mechanism. Wrote software that read the SISO DIS enumeration specification and auto-generated the DIS PDU classes, the DIS record sets and the DIS enumerations.

• Designed and implemented the Distributed Interactive Simulation (DIS) controller. This component provides the means to participate in distributed warfare simulations.

• Designed and implemented the ZedaSoft core Artificial Intelligence entity models. AI entities are easily configured to fly routes, automatically engage enemies, avoid attacking entities by flying avoidance maneuvers and to trade Link-16 information.

• Participated in the rearchitecture of the F22 cockpit demonstrator. Involved in design and implementation.

 

Senior Software Engineer, Tensor Information Systems

​1999- 2001 

 

Technical team lead for numerous software development initiatives. Involved in all phases of software development. Met with clients to identify scope and requirements, wrote proposals, wrote software requirements specifications, wrote design specifications, designed supporting database schemas, software implementation using a variety of development tools, software integration, deployment and test. All work was done in Java on browser-based applications and was accomplished using BEA's Weblogic Server and Apple's WebObjects application server.

 

• Team lead for a browser-based intranet cost-savings tracking application. The application provided users with the means to access up to the minute data for any savings proposal maintained in the database. Also provided a variety of dynamically generated line and bar charts, which showed performance of saving proposals by group, branch and division.

• Team lead for development of a public internet site dedicated to legal issues. The site provided its users with legal information, news, legal forms, a secure online storage system for files in any electronic format, bulletin boards dedicated to specific legal topics and a chat area that supported moderated chat sessions with a special guest.

• Team lead for the development of a browser-based workflow application. The application was developed internally as both a sales tool and a reusable component. The application provided users with a personalized to-do list of assigned tasks, the means to execute on those tasks, dynamically generated gantt charts showing both estimated and actual completion dates and a pegboard style display for viewing task status. The application also automatically made task assignments based on role and current task load. The application was implemented using BEA's Weblogic Server and J2EE principles. The workflows and tasks were defined using XML.

• Worked on a two-man team to develop a browser-based airline fare finding application. The application connected to Sabre Data Systems’ reservation system and kicked off multiple simultaneous fare searches based on a variety of criteria. The application was implemented using BEA's Weblogic Server and J2EE principles.

• Developed a browser-based document generation application. The application presented the user with two frames. The top contained a list of questions pertinent to the document that was being completed, while the bottom contained the document itself. As questions were answered, the lower section was dynamically updated using JavaScript. Document sets could be created so that multiple documents could share common data for a single user.

• Developed a bug tracking application that became an internal company standard. The application would automatically notify project leads and/or developers when new bugs were entered into the system, when a bug was assigned and when it was closed.

• Worked on numerous commission-based proposals with sales team members. Would meet with potential customers to ascertain their needs and then create a formal proposal for further development. Also responsible for estimating a dollar figure that accompanied each proposal. Won several business contracts.

• Elected President of the Employee Advisory Council. Responsible for gathering and delivering employee suggestions to executive management.
