Senior Software Engineer

Confidential, Folsom, CA

Responsibilities:

• In my second return to OSI, I have worked on a number of projects. I am currently working on the second generation of a JBoss(7) web application which presents a REST Easy interface to our new Alert Manager client application.
• This interface surfaces network management functionality through an XML API to NetExpert in the fault management domain. I have designed and implemented several JBoss services and ExtJS client components for this product.
• The latest service provides multi-session cut-thru services to dedicated gateway based network devices using a combination of REST and websocket interfaces. This application will eventually replace the Alert Navigator Swing client that I originally worked on in the 1998 timeframe.
• I have developed components as part of the Dashboard REST API into Confidential ’s performance management stack. This project represents my second crossover from the fault domain into performance management and is heavily entrenched in a Java, Jersey, Eclipse, Maven, and REST-Assured continuous build and test environment.
• I also assisted in the implementation of the NetExpert 10.0 C++ based Rule development editors. I had worked on this toolset before when it was implemented in C and was able to contribute to a few of the Qt/Nokia based tools before their initial release.

Environment: Java, Javascript, C++, JSON, RESTEasy, REST Assured, Jersey, JBoss7, ExtJS, Qt, WebStorm, Eclipse, IntelliJ, Jenkins, Maven, ClearCase, OrientDB, MongoDB, Perforce, yFiles for HTML.

Software Architect

Confidential, Sacramento, CA

Responsibilities:

• Our primary role was to provide software support for the web service based Transaction Router Gateway and Criminal Processor custom workflows. These include:
• Custody: This workflow was redesigned in a BPMN 2.0 format. Our efforts consisted of interviewing Department of Justice (DOJ) employees and developers, documenting the existing workflow in BPMN 2.0 notation, suggesting improvements to the workflow, and evaluating (3) potential workflow engines (Oracle SOA/BPM Suite, Active Endpoints ActiveVOS, and RiftSaw) for implementation. Mobile Identification
• This workflow provides a rapid response identification for mobile devices. It included a National Information Exchange Model (NIEM) XML Schema integration with the FBI's Next Generation Identification (NGI) web and Repository for Individuals of Special Concern (RISC) SNMP services. The current implementation is integrated with the DOJ’s Automated Criminal History System (ACHS) as well as the Automated Fingerprint Identification System (AFIS).
• My role in this project was to design and implement a JAXB XML schema integration with the NIEM data, build mock requests and response systems to simulate message traffic, and to drive testing with JUnit.

Java Software Architect /Technical Lead

Confidential, Fairfield, CA

Responsibilities:

• The SAWS project was initiated to add a major new product to Copart's auction systems and to address a number of high level architectural issues. The new product supports active seller counter - bidding in the real time auction environment. The architectural issues addressed were:
• Replace server direct stored procedure access with web services. This feature allowed throttling support to regulate the processing load on the primary database server. Replace proprietary packets over raw sockets connectivity to clients with a secure industry standard protocol (JAX-WS). This feature opened the door for third-party integration and offered a greater level of security for new and existing customers. Reduce time-to-market for Java web services development. JAX-WS development reduced the production time lines over our traditional Axis2 web services. Use of the non-proprietary messages also made modifying the protocol much easier for Java developers. The initial prototype was built using NetBeans and GlassFish. As the project went into active development we switched to JBoss (running the Metro web service stack), which was our target production platform for both the web service and EJB tiers.
• Stateless session beans were used between the web service tier and the Sales Facade EJB component. This component maintains the illusion of an always available socket connections to the Auction Server, even though these servers may only be running at specific times of the day.
• It also functioned as proxy for outbound client notifications through JAX-WS's asynchronous messaging. A MySQL EJB tier managed individual and shared client state. Individual state consisted of client user interface properties. Shared state was required to support locking of a sale by the seller representative during an auction.
• My role in this project was as principal architect. I created the proposed architecture, developed the initial rich client buyer and seller prototypes, built a serialized file persistence layer, and presented these to senior management and the main development team.
• I also created wiki based software architecture documentation (use case, class, sequence, and deployment diagrams, as well as, essential and real use case text). I also worked as lead developer with a team of six other developers once the project went into the development phase.
• This project involved the implementation of several key business features to enhance the user experience and integrated the buyer auction applet into Copart's next generation website. I implemented the majority of the client-side functionality, including:
• Movable panels with customized JavaFX and Swing image backgrounds. These panels can be fixed or slid out with animation into the frame's boundaries using the JavaFX animation and the Java timing-framework.
• These components were implemented in a JLayerPane composition of business components drawn over website style imagery. The main frame of the user interface, as well as the deployment model, is managed through JavaFX. This allowed out of frame pop-out panels and web page draggable installs to a client's desktop.

Environment: Java, JAX-WS, Axis2 (WS), DB2, RMI, Cream, JBoss5, Hibernate, Resin, GlassFish, NetBeans, MySQL, Swing, Struts, Spring, Applets, Servlet, JavaFX, JNLP, iBatis.

• Service Manager Object Modeler. Team lead, software developer for a Java client application which supports graphical network service design. This component of the Service Manager solution provided its users multiple
• UML-like Class and Object diagrams of the NetExpert MIM and also functioned as a gateway to import external XML definitions of the Service Manager objects. This project employed an MVC architecture centered around controller threads for data retrieval and validation. It used YWorks generated graphs with file and socket based XML persistence.
• Topology Viewer. Designed and implemented this integrated multi-view / multi-protocol application. This program provided customized yFiles Graph2D based views of discovered IP, MPLS, and VPN network topologies. It was used as the central vehicle to present the MPLS/VPN discovery mechanism. Its data model was created by a JDO Fast Object data source.
• Trouble Ticket integration into the Multi-NCC/VSM server. Along with the Online Advisor module the Trouble Ticket functionality was integrated into the multi-VSM design.
• Object Browser plug-ins. Both the Fire Hunter and Relationship plug-ins were developed as part of a Vodafone solution.
• Virtual Service Adapter (VSA) Policy Engine. Implemented segments in support of a device discovery project. Developed J2EE stateless session beans as part of the Discovery Manager project.
