Projects:

• Implemented front end for "row level security" in the Pentaho Metadata Editor tool.
• Co-developed Pentaho Aggregation Designer, a graphical user interface that simplifies the creation of aggregate tables that improve the performance of queries against OLAP cubes. The tool's user interface was created using XUL.
• Served as primary point of contact for questions, defect resolution, and improvements regarding the Pentaho BI Server security system . Developed extensible access layer for querying LDAP directories for security-related information in the BI Server.
• Developed and installed into production a single sign-on (SSO) implementation for the JBoss-based Pentaho BI Server by integrating with Central Authentication Service (CAS). Pentaho SSO CAS
• Provided extensive assistance to Pentaho support , training, and sales departments by participating in numerous Pentaho BI Server security-related engagements. Lead a session at a Pentaho Partner Summit that by all accounts was a large success. Addressed questions from Pentaho forum users (in the top 15 most prolific posters). Pentaho forums
• Created thorough documentation and numerous HOW-TOs, making Pentaho BI Server security one of the best documented areas of the platform. Pentaho wiki
• Initiated the implementation of Pentaho Commons, a reusable code repository . In addition, presented session on test-driven development to engineering team. Finally, served as one of the champions of a repository-based build system (like Maven or Ivy).
• Contributed to other open source projects . Opened 7 defects in Acegi Security. Supplied code and testcases for 3 defects. Spring JIRA
• Authored a major user interface component (the properties editor) of the SWT-based Pentaho Metadata Editor. Also, authored the LDAP configuration tool for the Pentaho Management Services Console.

Projects:

• Designed and implemented extensible web application security infrastructure according to OWASP best practices. Used Acegi Security to provide transparent authentication and authorization. Encapsulated user management (e.g. registration, password retrieval, administration) into a separate web application whose services were shared by client web applications. Modeled user management web application after Microsoft Passport—one site for account services with many clients of that site. Designed security infrastructure to support users from heterogeneous datastores such as Microsoft Active Directory and relational databases like Oracle with graceful degradation for unsupported operations. Provided verbose auditing as well as account lockout was implemented using the Observer pattern. Created custom single sign-on (SSO) implementation that seamlessly integrated with Acegi Security's authentication mechanism. OWASP
• Served as the primary implementer of initial data layer, business facade, and reusable UI elements for Fairfield Resorts' primary external web site using established enterprise design patterns . Used Hibernate for object-relational mapping and Spring DAO support for data access objects. "Wired" dependent objects together using Spring's bean factory functionality while also providing per-environment "override" configurations. Designed common, reusable page elements using Tiles. Followed Spring conventions of judicious use of Java interfaces and runtime exceptions . Introduced transformation layer to allow Hibernate POJOs to differ from the business objects, allowing design of data layer and business facade to proceed independently and in a manner convenient for each.

• Assisted operations personnel with the configuration of development, integration, and staging environments in addition to a production environment. Configured clusters and servers in WebSphere including virtual hosts, datasources, and shared libraries .
• Served as build manager for application builds using Ant, administrator for version control and continuous integration systems (ClearCase and CruiseControl respectively), and system administrator of shared development machines.

Projects:

• Designed and instructed an object-oriented programming course based in Java, covering topics such as Java language elements (variables, control structures, and assignment), classes, interfaces, and objects, constructors, methods, instance vs. static, inheritance and composition, data structures, exception handling, and Swing GUIs.
• Assisted in the instruction of an enterprise technologies course including J2EE APIs, covering topics such as distributed applications, concurrency, JavaBeans, security, and remote method invocation (RMI).
• Instructed the recitation of a discrete mathematics course , a notoriously difficult course in the computer science curriculum. Topics included combinations and permutations, set theory, functions, and state machines.

Projects:

• Employed Jini and JavaSpaces to build a distributed, asynchronous system used in an exhibit called "MeasureMe." Jini provided service discovery much like UDDI does today. JavaSpaces provided simple, anonymous access to shared data . Red Hat Linux-based server running PostgreSQL database acted as persistent storage. Microsoft Windows clients running Java Swing acted as graphical interface for science center visitors. Extensive use of RMI between client and server. Used Java Communications API to interact with custom measurement hardware connected via serial ports. MeasureMe

Projects:

• Supported regression testing by release certification team. Enhanced data-driven regression test scripts written in Mercury Interactive's Test Script Language (TSL). Executed test scripts using WinRunner. Stored test results using TestDirector.
• Streamlined disk imaging process for rapid environment changes.
