|
•
|
Java expert with experience in the development of responsive, scalable, and robust applications.
|
|
•
|
Adept at architecting, designing and developing entire application systems, from web/rich client user interfaces to business logic components and the database tier.
|
|
•
|
Knowledgeable of lightweight open source technologies including the Spring Framework.
|
|
•
|
Experienced in object-oriented software design including the use of design patterns and UML.
|
|
•
|
Proficient in unit testing, acceptance testing, and performance/scalability testing and tuning.
|
|
•
|
Skilled in agile software development methodologies.
|
|
•
|
Effective at requirements gathering, analyzing risks and choosing appropriate technologies.
|
|
•
|
Produced a maintainable and extensible architecture through the abstraction of protocols and underlying technologies/APIs. Design supported the use of multiple specifications for connecting participants to a single call conference, each party potentially relying on a different network element make/model/release. |
|
•
|
Developed a redundant, highly available call routing system through the use of clustering and load balancing. Addressed failure scenarios. System allowed for hot upgrades. |
|
•
|
Provided an agile, reliable, efficient software development environment by driving the overall source code repository structure, build framework, continuous build system, and automated code review tools for the entire project. Environment allowed a team of twelve developers across multiple sites to seamlessly contribute and integrate software components. Regularly delivered high-quality software artifacts to a dedicated SQA team. |
|
•
|
Allowed individuals to obtain a cluster-wide visual representation of the messaging and software interactions involved in a call by developing a network traffic tracing tool. The tool proved to be invaluable for analyzing and debugging 9-1-1 calls. |
|
•
|
Met the challenging planning needs of the WorldView spacecraft by implementing required functionality, reducing defects, refactoring, and increasing test coverage of sophisticated system components including a manual scheduler, ephemeris/contact plan ingester, tasking feasibility assessor, and collection opportunity generator. |
|
•
|
Provided a comprehensive view of the state and health of the entire CPS system through the development of a web enabled monitoring application and diagnostic engine. Developed using dependency injection and Spring MVC, the application was delivered three months ahead of schedule. |
|
•
|
Reduced coupling to remoting technologies and simplified system architecture by introducing advanced Spring features such as lightweight remoting to the project. |
|
•
|
Deepened awareness of dependency injection and general programming best practices by giving presentations to the team. Discussions helped eliminate plumbing code, promote pluggability, and structure whole applications in a consistent, productive manner. |
|
•
|
Increased planning efficiency with the development of an interactive graphical satellite tracking tool used to display ground tracks, cloud cover forecast data, image strips, and order polygons. Developed using the Eclipse Rich Client Platform, GeoTools, SWT, and JFace, the application is instrumental in visualizing satellite capabilities and maximizing imagery collections. |
|
•
|
Evaluated and incorporated appropriate J2EE technologies into the project to help guarantee a robust, transactional, and scalable architecture. |
|
•
|
Introduced the open source model of software development. Cut development time and project costs by integrating open source tools, technologies and platforms such as Linux, Tomcat, MySQL, Struts, Spring, JBoss, Log4j, Ant, and JUnit. |
|
•
|
Developed and implemented the database model for the application, including identifying the entities, attributes and relationships, normalizing the model, and developing the physical database design. |
|
•
|
Provided a high level of confidence in the code through automated unit tests. Treated testing as an integral part of the development process. |
|
•
|
Increased scalability by over 80% through deliberate performance testing and tuning. |
|
•
|
Achieved customer satisfaction through early and continuous delivery of useful software components. Used agile software development methodologies to create flexible software that adapted to change. |
