http://docbill.freeshell.org
I have been designing and developing software professionally full time for 11 years, and part time for an additional 6 years. Although I am experienced with a wide range of technologies, I specialize in object-oriented solutions and prefer to work with Java and C++. My core skills include leadership, design, and programming. I am experienced as a manager, software architect, and software designer. 50% of my experience has been as an independent contractor and 50% as a direct employee for AT&T, LizardTech Inc., and Red Hat Inc. References are available upon request.
Specializing in object oriented enterprise and application solutions using Java (J2ME, J2SE, J2EE, JB, EJB, Spring, Hibernate, etc) and Perl.
Projects:
Command Center Port and Redesign (Senior Software Application Engineer)
Rewrote UI code for the Command Center hosted service. The original code ran under Solaris using Dynamo. Dynamic pages were rewritten as jsp, and the java code was rewritten using Spring, Hibernate and Weblogic. The service is now hosted under Red Hat Enterprise 4.
Command Center Software Scout (Senior Software Application Engineer)
Designed and developed a UI interface as a webmin module for configuring and provisioning a software scout. A scout is a dedicate machine that runs on a client's network to monitor services. Now customers install the software scout on their own hardware, rather than renting a scout from Red Hat.
Specializing in object oriented enterprise and application solutions using Java (J2ME, J2SE, J2EE, JB, EJB, etc.) and C++.
Projects:
Virtual VRU: (Lead Architect and Lead Developer)
Developed a virutual VRU for IVR applications to exchange call control messages with a Cisco ICM PG controller using JMS messages. The Java code used J2EE 1.3, and J2SE 1.4. The solution was developed in the Windows NetBean 4.1 platform, tested on the Windows Websphere 5.1 platform, and production deployed on AIX Websphere 5.1.
Transmission Stator Blade Design: (Lead Architect and Lead Developer)
Developed a GUI application for designing stator blades, displaying real time 2D and 3D views, analyzing, displaying analysis plots, displaying data views, printing, and exporting data to other applications used for designing automobile transmissions. The C++ code uses QT, Qwt, and QT VTK toolkits. The solution was implemented with MFC for Windows platforms. The code was designed to be portable to Linux and Mac OS X.
Java DjVu: (Lead Architect and Lead Developer)
Developed a pure Java Applet for decoding and viewing multi-page DjVu documents using J2SE, J2RE, and J2ME. Solution designed for Mac OS 9.2, Mac OSX, Red Hat Linux, Windows XP, and WinCE.
