Consultant - Java Applications

Responsibilities:

• Developed an interactive two-dimension meshing code (JAVA) with variable cell for a two-dimensional magnetotelluric modeling. The interface allows the user create a properties model by point, click and drag. The model is then interfaced with a backend FORTRAN program to calculate the results which will be displayed graphically.

Senior Applications Engineer

Confidential, Monterey, CA

Responsibilities:

• Continue development of OPARS UFS ( Optimum Path Aircraft Routing System - User Facing Service) at U.S. Navy's FNMOC in Monterey, CA (see below). The development of a fully functional web application that meets PKI requirements to replace the existing thick-client desktop application. Tasks included:
• Develop the route builder to allow the user to select departure and arrival points through several methods, such as airport or naviad ICAO or name search or geo-location. Allow the user to create a route manually (through a series of web pages), graphically (interactive), by keyboard entry or stored file of previous routes.
• Enhance and standardize the route builder data service to make it consumable to outside entities.
• Overlay the flight planner output graphically onto a map (using JavaScript and OpenLayers).
• Development of a map server and graphical overlays of jet routes, navaids and airport it enable the user to create a route dynamically (point and click) on graphical objects on a input map on the web page (the aviation and geo-data are asynchronously retrieved from the database via AJAX and JSON). Development of interactive charting (plotting) web pages which enabled the user to display various flight information and statistics for waypoints on the flight path.
• Development of interactive selection lists from JSON data which allows the user to view the list sorted depending on the header selected and then execute the desired request. Support displays in several GIS client including Geoserver, Google Maps and Google Earth (KML file output). Integrate OPARS routing components with Flight Weather Briefer (outside service).
• (Perl, CGI, HTML, JavaScript, AJAX, JSON, XML, Java, KML, and SOAP::Lite, Google Map, Google Earth)

Perl Programmer

Confidential, Sunnyvale, CA

Responsibilities:

• Developed and enhance company’s e-commerce subscription and in-house administrative and reporting ASP running on mod-perl on Linux OS. Perl HTML::Mason and Template were used for the CGI to produce dynamic HTML pages, page content was dynamically created based on the user input (AJAX) and all inputs were verified on client-side (JavaScript) and sent to the server (XML, AJAX) with the back-end database (mySQL).
• (Perl, CGI, HTML::Mason, Template, HTML, JavaScript, CSS, AJAX, XML, mySQL)

Perl Web Programmer

Confidential, Monterey, CA

Responsibilities:

• Contracted to the U.S. Navy FNMOC to deploy a web user interface for the Optimum Path Aircraft Routing System (OPARS) project using Perl CGI on Linux OS.
• This includes the development, modifications and integration of new and existing codes as pertained to the implementation of the OPARS UFS (user facing services).
• The OPARS UFS is a dynamic web application based on the existing thick-client desktop application which allows a user (pilot) to build a complete flight plan from available aviation and geo data.
• This project was previously abandon by another contractor so my task was to develop a workable web application (developing flight plan request and displaying acceptable results) with the remaining allocated time of 2 months. This included entering aircraft parameters, such as aircraft information, fuel type, and other flight parameters, and creating a flight plan (route) by using the existing data of airports, jet routes and navigational aids.
• For the OPARS-UFS the page content can be dynamically modified based on the user inputs which updated the data via JavaScript and AJAX.
• The request all inputs are verified (client-side via JavaScript) and submitted to the server via SOAP for validation and processing.
• The resulting flight plan can be displayed either by text or graphically via parsing the XML SOAP response.
• Due to the large and associated make up of accessible data (aircraft type, airports, navigational aids and flight segment legs), a requirement for this project was to investigate, recommend and deploy the data storage components needed to support the OPARS UFS.
• (Perl CGI, HTML, JavaScript, XML, SOAP::Lite)
