• Helped educate the overall product team on the proper use and internal coding of EJB’s and servlets, and helped diagnose and debug issues that were seen with these in other modules. Used Java heap dumps, logs and other artifacts to track down other overall coding and architectural issues, and recoded and re-architected portions of the product as necessary.

• Liaised with the client on installation, configuration and modifications as needed.

Confidential, Dayton, OH

Responsibilities:

• Worked on a flagship J2EE project to recode part of the Confidential backend search infrastructure in Java on IBM WebSphere. Previously, this was coded almost entirely in MVS assembler. This piece, search normalization, was redesigned to run as a stateless session EJB while maintaining communication with other appropriate assembler modules via JNI, and also while accessing necessary disk files. This module also had to be internationalizable, and perform its tasks withing a tight processing timeframe budget, despite needing to eventually handle all of Confidential search transaction volume. Currently, it performs its tasks in an average time of slightly under 10 milliseconds per call. Continued to work on this project to implement new features and products.
• For the above project, also helped design and write the Ant build process and scripts, and ClearCase source code layout.
• Worked on another flagship J2EE project to help extend more of the L-N search infrastructure into the Java/J2EE environment on IBM WebSphere. Again, this was designed as a set of stateless session EJB’s communicating with existing infrastructure (including the previously mentioned search normalization EJB) to perform tasks including online message processing and loading and activations, loading, and deactivation of online search databases. Also helped develop the team’s Ant scripts and ClearCase layout for source code. Helped mentor team members in Java/J2EE development and use of developer tools, such as WSAD.
• Worked on a custom tool, WCT, designed to enable provisioning and configuration of internally developed WebSphere applications to their remote servers on Unix and Windows. Written entirely in Java, it was cross platform and completely integrated into the Ant build/scripting tool. This also utilizes numerous XML technologies, including XSLT.
• Worked as part of a team that investigated, prototyped and disseminated information on Java/J2EE technologies throughout Confidential . Out of this work came the company adoption of standard developer tooling, such as WSAD for development and Ant for repeatable builds, ClearCase for source code control, and many others.

Confidential, Cincinnati, OH

Software engineering consultant

Responsibilities:

• Developed a ground breaking n-tier system for a large health insurance provider in north Cincinnati that keeps track of patient clinical history, and performs other important tasks such as pre-authorization of procedures, and automation of reviews of acceptance/rejection decisions. It utilizes DCE RPC’s for communication to the server portion of the system, large scale Sybase databases for data storage, a transaction processing monitor (Encina), a custom written client program (written in Visual C++/MFC for Windows NT), and custom written server processes (written in C++ for AIX). My work on this system included:
• Worked on the client program for Windows NT, developing a number of client features. Designed a set of classes to represent and encapsulate the M&R (Milliman and Roberts) medical treatment guidelines, which are used for specific combinations of conditions and treatments, and designed and wrote the code for the UI representation. Later retrofitted this same code so that it could be used by other developers in other parts of the client. Worked on a number of other client software features as needed. This development work involved heavy use of ‘Design Patterns’ focused design and development, heavy use of the STL/C++ Standard Library, use of 3rd party Active X controls, designing/writing code to use DCE RPC’s for communication to the server side of the system. Gained experience in the use of UML diagrams for both class design and documentation.

Confidential, Dayton, OH

Software designer

Responsibilities:

• Worked on the Teleres Workstation, a specialized n-tier online system designed to be used by clients involved in the real estate investment securities trading industry. The system was designed to be used with a custom written, Windows NT based client software, with an automatically load balancing set of server machines delivering both structured and free text, unstructured data to the client. At the time Teleres was a division of the Confidential Corporation, and the Teleres Workstation was launched with full page ads in ‘The Wall Street Journal’ in late 1995 and early 1996. Eventually became the development lead of the team responsible for writing the client application (written in Visual C++) to deliver electronic version of various print publications, as well as articles from the Confidential newswire feed, to the client desktop. Designed mechanisms to not only perform efficient searches on demand, but to allow users to build and maintain ‘profiles’ to be used to automatically ‘push’ content to the client desktop. Worked closely with backend developers to determine capabilities and development strategy, and worked with Teleres to determine future direction as necessary. Also worked on a number of other smaller code components for use by members of other teams as necessary. Together, the entire development team working on the Teleres Workstation achieved a measured benchmark of approximately 5 bugs per every 10,000 lines of code written.
• Later worked on the server processes for this same system, writing code in C++ using the AIX compiler. Focused primarily on processes and database tables that contained member data, which ranged into the mid millions of rows. Also wrote server processes to deliver various types of review data to the client, as well as performing reviews of virtually all server code with DBA’s to determine performance bottlenecks, and provide remedying code and queries as necessary. The code/queries also had to be retrofitted to allow for regular upgrades in terms of the number of users of the system (as it was rolled out to new service areas), as well as additional members (when the system was used for members in additional states). Again, ‘Design Patterns’ and UML were used extensively in design and coding. Also led changes to allow the ‘read’ server processes to use stored procedures (using Transact-SQL) rather than hard coded SQL.
• Also performed a number of duties for a large retailing organization with offices in Cincinnati. Worked on retrofitting a web based reporting and appointment scheduling system for seasonal hiring from Netscape based web servers to Microsoft IIS, where the system used Microsoft SQL for data storage. Gained experience with Microsoft ASP technology.
• Worked on the design and development of the Blaze Web Performance Pack, a ‘shrink wrapped’ retail software package designed to speed web access from ordinary browsers up to a theoretical limit of 8 times faster than normal. Worked closely in the design of the algorithms used to access and download treated web pages, designed and wrote proof of concept and benchmarking code, and designed and wrote the code to perform ‘on the fly’ decompression of treated web pages. Also designed and wrote code for various parts of the client program, which was designed to work on all flavors of 32 bit Windows. Gained experience in writing code to be run from the 32 bit Windows system tray, code to interface to web browsers, and in HTTP protocol extensions, as well as writing object oriented C++ code.
