  Software Engineer

  The original and primary developer of the user interface for the Amphion control system, responsible for the creation and maintenance of about 650,000 lines of code. The main operator screens run in a highly configurable Java applet, which contains a system to navigate between screens. Each screen is stored as an XML file, which describes the content of the screen. I am also responsible for the creation and maintenance of a Swing editor application to allow tool specialists to develop screens for each tool using an intuitive GUI interface. Individually responsible for a configuration system for profiles (for assigning hardware devices), roles (for different types of operators), and tool permissions. The system includes a way to easily configure an oil rig hardware display monitor, identified by its MAC address, with a set of permissions (view and write permissions) corresponding to a specific operator, so that only certain people can operate certain tools in specific locations. Individually responsible for a set of service software tools designed for specific purposes, such as transferring files via an HTTP interface, monitoring low-level parameters on controller computers in real time, diagnostics for TCP/IP networks using SNMP, diagnostics, version reporting, software component installation, collection of debugging information, operator permission configuration, simulation control, date and time control, and managing alarm triggers. Some applications were developed using the JQuery JavaScript library, and some were Java applets. Also responsible for HTML pages to support the applets including CSS and JavaScript. Responsible for Java Swing applications including an offline graph viewer and data collector application. Also included is an application to create UML state diagrams and an associated Java applet for interactive display of controller state transitions in real time. This also included an application to edit motion paths for path-based oil rig tools. Show less
