PROFESSIONAL EXPERIENCE:

Confidential, Reston, VA

Senior Java Developer

Responsibilities:

• The main tasks are to develop custom CQ/AEM components (which allow customer users to author/maintain their own content) and to handle some data/content issues which are too technical for authoring personnel. In addition to the web interface that Adobe uses to manage CQ/AEM environment, Github, SourceTree and Netbeans are used to develop/manage custom components as JavaScript, Java Server Pages (JSP) and Java Servlets.
• Tasks have also include developing Extract, Transform and Load (ETL) tools for automatically loading either 'raw data' or converting content from a legacy CMS into Adobe AEM/CQ.
• Have created custom tools in both framework and software toolbox contexts to generate custom reports from the CMS repository as well as automate large changes to the repository. Used scripts to automate image processing tasks.
• Designed and set up a SolrCloud configuration of Solr for Enterprise Search capability, including an “adapter” web-pattern that would allow Solr instances to co-exist with Confidential Mini Search Appliance clients. Developed a custom AEM-based crawler for SolrCloud, in addition to Apache Nutch
• Designed and set up a fully redundant Esri middleware layer, involving both Tomcat and Apache Web servers, for interfacing an Adobe AEM-based GIS app to the Esri ArcGIS environment
• Responsible for providing technical guidance / support for non-technical peer personnel.

Confidential, Charlottesville, VA

Senior HMI and Java Software Engineer

Responsibilities:

• Used Java Swing heavily, including the Apache Batik component for rendering Scalable Vector Graphics (SVG) within Swing. Used Java 1.8 in the GUI. Java 1.4 is used on the embedded side to maintain compatibility with the hardware Java VM chipset (by Agile) boards.
• Responsible for architecting future highly generic software systems to generalize solutions to many Robotic Operating System (ROS) environments and applications.
• Specified a C2I web server design to support system awareness for the robots and their human users as well as light-weight, highly-specialized, yet flexible Java Swing JFileChooser to allow user’s to share and backup arbitrary files associated with robot testing across many ‘robot controller’ laptops.

Confidential, Boston, MA

Senior Multimedia Scientist

Responsibilities:

• Duties included tracking down/fixing software defects, implementing new functionality and analyzing difficult / defective media in order to find new strategies to make the Nexsys system more fault-tolerant and robust.
• Researched, installed, configured and documented a Hadoop 2 / YARN cluster using Virtual Machine (VM) technology to support the proposal of an actual hardware-based system.
• Ended when hoped for customer contract was not forth-coming.

Full-time Independent Consultant

Confidential, Manassas, VA

Responsibilities:

• Working as “Senior Software Developer” on Confidential submarine acoustic (sonar) and visual (mast) data collection, analysis and visualization systems.
• Duties included understanding and implementing customer requirements, primarily on the User-Interface client-side but also some solution implementation work in the backend systems.
• Included gaining additional Java experience in the context of a very large “SOA in a box” implementation, using RCP plug-ins with an Eclipse framework for developers as well as a heavily automated “batch” software building tools, including Buckminster and Jenkins.
• Implemented an intelligent message corner-turning system allowing a legacy back-end C++-based systems to continue using Corba messaging while the front end Java-based User-Interface software switched over to AMQP messaging using Confidential protocol buffers.
• Team coordination was handled in part via Redmine and Wiki technology.

Full-time Independent Consultant

Confidential

Responsibilities:

• Working as “SOA Architect” on a entity-wide project for the Confidential ( Confidential ). The purpose of the project was to build a fully operational demonstration of fine-grained, multi-dimensional and externalized (i.e. not embedded in software) access authorization mechanism for sharing data across Confidential SOA applications while ensuring all legal and privacy concerns were verifiably met.
• The solution consisted of using the XML Access Control Markup Language (XACML) in which access restrictions are formally stated as XACML policy files. At run-time, user-oriented requests for data were converted into XACML Requests and these then run against the policy engine. A XACML Response was generated containing access authorization results.
• If the access decision was ‘Permit,’ the original request was forwarded to the ultimate data source for fulfillment.
• Worked on the Java Swing client responsible for initiating the initial request and then displaying access authorization results as well as any permitted data returned.
• Also implemented the backend consisting of a REST data service which accessed a MySQL database of synthetic person data.
• A virtual machine implementation of the Layer7 SecureSpan Gateway processed the policy-related XACML, acting as PEP (Policy Enforcement Point), PDP (Policy Decision Point) and PAP (Policy Access Point).
• The entire system executed in a cloud environment maintained for Confidential by the Confidential.
• The resultant proof-of-concept system completely satisfied that portion of the Confidential contract. Ended with sudden loss of customer’s funding.

Full-time Independent Consultant

Confidential

Responsibilities:

• Working as a “one-man software development / IT team” responsible for all of this small company’s software needs.
• Tasks have included creating a rich, web-service client, starting from scratch (i.e. a PDF file description and the web-server WSDL) to having the result deployed at technician workstations over a 3 day period. Work has also included programming barcode readers and generating, from within a Java program, PDF files containing scan-able barcodes for values taken from the Internet that were previously input by error-prone, manual data-entry.
• Developed software that would automatically navigate (via the Selenium tool) through a series of secure (HTTPS) pages on a supplier’s web-site in order to mine / scrub data that should have been available via web services but was not.
• Also investigated a crucial (though disliked) commercial software package and determined how it was using an underlying MS Access database and developed Java code to utilize this database so that missing desired functionality could essentially be added without relying on a costly, and frequently unresponsive software vendor.
• Developed code to cleanup the in-house database (removing inconsistencies, duplications, etc.) and supporting a sales marketing campaign by automatically generating ‘static’ web pages which potential customers would be able to find though Internet search engines (e.g. Confidential ) and then be drawn into the rest of the largely dynamic web site.

Full-time Employee

Confidential

• Enterprise Java development for a large government intelligence management and collection.
• The first implementer of a new NATO common XML tasking format including both disk and web service output.
• Also implemented a double-sided, customer utility for exporting intel missions from one PRISM system and then re-importing them to another system with potentially different security classifications and conflicting database keys. Included leading oversight responsibility for small software development teams.
• Developed a tool using Java Reflection that would sift through compiled JAXB output and then generate nested and comment-annotated Java code corresponding to the JAXB client invocations necessary to build an object for marshaling.
• As a result, the drudgery and expense of much manual code creation was eliminated and programmers unfamiliar with JAXB were able to readily participate in code development.

Full-time Independent Java Consultant / Contractor

Full-time Independent Java Consultant / Contractor

Confidential

Responsibilities:

• As part of a DOD research project and in conjunction with a DOD project-of-record, developed a Java-based, super-scalable, hot-extendable, generalized system analysis/management environment.
• The XML-based scalable vector graphics language, SVG, was used in order to allow non-programmer customer personnel to provide their own system diagrams.
• A database was provided in order to allow the system and its message handlers to create and maintain persistent data.
• A communications environment was created that allowed each instance of the system to communicate either “upstream” or “downstream” to other cooperating entities.
• The graphics subsystem, database and communication facilities were all carefully, architecturally abstracted so that no vendor, platform or technology dependencies were created.
• The system was developed so that it could be augmented with new messages and their corresponding message handlers without having to bring the system down. This research system was readily and successfully applied to a separate contract for a deliverable submarine subsystem to the Confidential .
• As part of a DOD research and development contract, created a next-generation, Java-based acoustic data analysis station for the Confidential ’s P-3 submarine hunter aircraft, including both man-machine interface (GUI) and background processing.
