Jaguar Project Developing an installation application that deploys a web-based medical management application at customer sites running the Microsoft Windows, Linux or Unix operating system.

• Working as part of a Scrum agile software development team to identify requirements, priorities, and review progress.
• Evaluated suitability of Java installation frameworks and selected Install4J.
• Created Maven projects that assemble resources needed to deploy the application and its data.
• Wrote JUnit tests run nightly by CruiseControl to ensure resources are still deployable.
• Design and implement graphical and console user interfaces that guide users through installation.
• Perform usability testing to identify opportunities for improvement.
• Write custom validation methods that ensure user entries do not contain mistakes.
• Have created custom installation actions that load databases, create the initial administrative user, and install the application to either a JBoss or WebSphere application server. The custom actions accomplish their missions using embedded Ant, wsadmin Jython scripts and business tier components of the medical management application.

• Analyzed and clarified business rules provided by clinicians, architected and implemented Fair Isaac Blaze Advisor rule services that validate clinical data.
• Worked with the team to extend the application domain model to support clinical data validation.
• Created JUnit tests driven by XML data to support the rule service development.
• Designed a mapping component that translates clinical data from multiple data sources into Java domain model objects based on a table driven configuration. Built the tables that drive the mapping and implemented the mapping component. Integrated the mapper into the application where it is used to feed the business logic.
• Implemented business rules in Java that screen clinical data for sensitive values. Created tables to hold the various types of sensitive clinical values and implemented entity beans that retrieve the values.
• Modeled clinical data validation logic as an ontology using OWL-DS and SWRL rules. Tested the ontology through the Protege-OWL API using JUnit tests driven by XML data.

Clinical Intelligence Rules Project Developed a set of clinician defined business rules that alert Medical Care Organization staff to members who are candidates for disease and case management.

• Acted as technical lead, identified risks and worked with the team to resolve them.
• Analyzed business rules defined by clinicians and architected a Fair Isaac Blaze Advisor rule repository structure that supports novice rule developers implementing the rules.
• Drove the creation of a clinical information domain model in UML optimized for efficient rule evaluation.
• Created Java POJO Business Objects, Data Access Objects and Hibernate mappings for the domain model.
• Added business object methods that precalculate values needed by the business rules. The use of these methods led to a 10 time speed up of some rule evaluations.
• Developed a web-based Rules Maintenance Application that is being used to define a set of model rules and allow addition of customer specific rules.
• Developed Ant based automatic build and deployment scripts.
• Completed the project on schedule as part of a Scrum agile software development team.

AutoScheduler Project Developed a batch application that automatically triggers recurring correspondence and Medical Care Organization care for members based on customer defined business rules.

• Led the integration of the Fair Isaac Blaze Advisor business rules engine into MEDecision's existing development processes.
• Devised and implemented a strategy for deploying user-modifiable business rules to customers.
• Developed a web-based Rules Maintenance Application that is used by customers to maintain their rules.

Project Lead, CarePlanner Web Project Developed a web-based utilization and case management system for Medical Care Organizations using J2EE and XML/XSLT technologies.

Infonautics, Inc., Wayne, Pennsylvania
Senior Software Engineer

Brewery Project Developed a Java servlet-based intranet content management system.

• Designed and implemented using Java servlets, JavaScript and HTML the front end of a subsystem that supports defining and managing sets of documents within the content store.
• Developed the rule language used to define document sets. Performed usability testing on the initial version of the language and redefined the language to make it more powerful and easier to use. Wrote a parser for this language that translates between document set rules and the language used by stored procedures in the Oracle backend.
• Created a custom HTML servlet base class that dynamically generates HTML based on HTML template files. Other content management servlets inherit from this class.
• Developed a session-based servlet base class that checks whether users are currently logged in and redirects them to the log in page if they are not. Other content management servlets inherit from this class so they do not need to implement their own session management code.

Advocast Project Developed a World Wide Web subscription online publication advocacy service. Implemented the client user interface in HTML and Javascript and CGI's in Perl and C utilizing an Oracle database. Analyzed problems that were causing slow initial downloads and doubled the download speed of the initial page.
