July 2002 - Present    BT Conferencing, Inc.     Braintree, MA
Team345 Consultant



Member of the Architecture and Design Team. This group is responsible for the architectural roadmap of the development team as well as project design approval and guidance. Personal responsibilities include serving as Technical Lead on various projects (2-5 people), managing deliverables and timelines for design, implementation, testing, and release

Designed and implemented a new SOAP version of the API for the redesigned API layer using Apache Axis. This version of the web service supports nearly all existing API functionality, user authentication and authorization, and segregated web services and WSDL files. The SOAP API provides alternate access to the application functionality for clients unable to use the existing internal web application.

Redesigned and implemented API layer of application to use Hibernate as a persistence mechanism rather than EJBs. This included a full rewrite of the system interfaces and database schema to support a migration of UK systems into US systems. Extensive build-time file generation was employed to reduce development and maintenance. This redesign resulted in a 35% decrease in the number of classes, and a nearly 50% decrease in the lines of code, without the loss of any functionality.

• Created an xml and Java framework for management of HQL queries. All complex dynamic query setup is maintained in xml and Java wrappers for client use are created at build time. Adding new search fields requires only an xml edit, recompile, and setting of new bean properties by the caller
• Created common base classes that provide consistent, nested, xml-formatted toString output, equals, clone, hashCode implementations
• Created a generic Differences mechanism to provide historical tracking of changes to any simple or complex object in the system. This ultimately displays in the UI as a History page showing the who, what, when and why of changes to accounts, contacts, meetings and other entities.



Designed and implemented several Stateless Session and Entity EJBs. The Entity beans utilized Container Managed Persistence (CMP). Many of the Session beans used JDBC for direct access to multiple tables where performance was an issue. The Application Server was Oracle's Orion Server (oc4j). Development was performed from within JDeveloper and JBuilder.

Designed, prototyped, and implemented Java Struts and JSP front-end of web application used by Customer Service Representatives to maintain accounts, contacts and meetings. The Java Server Pages (JSPs) and Apache Struts framework are used in conjunction with Apache Tomcat 4/5. For maintainability and performance, I created several custom JSP taglibs.

Designed and implemented SOAP-based API for the application using Systinet's WASP Server for Java. Selected functionality was exposed through WSDL and Web Services, with an additional layer of data validation and external contact conversion added.

 

May 2002 - June 2002    MetraTech, Inc.    Waltham, MA
Team345 Consultant (onsite)


Assisted in Functional and Technical design of teleconferencing billing solution.

Designed, prototyped, and implemented a web service for remote calls from Windows to Solaris using SOAP.  The web service was used to integrate the MetraTech platform (Windows 2000) with existing tax software on Solaris.  Microsoft SOAP Toolkit was used on the client and Systinet WASP C++ SOAP on the server.  Also researched other SOAP implementations,  including Apache SOAP.  Design included fault-tolerance and scalability solutions through WSDL definitions and client code.

 

July 2001 - April 2002        Blackstone Technology Group, Inc.    Worcester, MA
Team345 Consultant (offsite)


Responsible for building administrative management application using Java Swing components.  The client-server application makes extensive use of JTables and JTrees, and provides GUI tools for monitoring and managing the system data.

• Assigned to fix time critical and difficult bugs such as repaint issues in other areas of the application.
• Addressed slow application startup times, improving startup performance by 40%.

Responsible for designing and creating the product installer using InstallAnywhere.  Tasks include screen flow design, gathering of component and OS dependencies, creating custom code and custom input panels, and build integration.


 

Dec 2000 - Jun 2001     SmartLynx, Inc.    Londonderry, NH
Senior Software Engineer


Responsible for building one C++ spoke in a hub and spoke architecture that allows various engineering development tools to share designs through a central point.  All communication with the hub and other spokes is through XML.

• Under own initiative, addressed performance problems in the system (hub and spoke), bringing processing time down more than 99%
• Rewrote the "writer" half of the spoke in Java.  The original spoke development was outsourced to 3rd party contractor and proved to be un-maintainable.
