The Echo Group
(October 1997 - October 2002)

Company/Job Description

"The Echo Group produces information management software for behavioral and mental health care providers and centers nationwide, including two thirds of California's county mental health agencies."

I was part of a small rapid application development team that was distributed across several remote offices. Our team's style was to thoroughly document design and analysis, and to keep a heavy focus on the architectural framework, while still maintaining a rapid development cycle (much like Extreme Programming).

Note: my initial employment was as a contractor with the Oakland software division of United Behavioral Health. This division was acquired by Echo in July 1999, at which time I became a full-time employee.

Project Details

• Scheduler subsystem of Echo's flagship web application, ShareCare. Code cleanup and reverse engineering of the previous version. Complete rearchitecting and redesign of an enhanced version, including availability, complex recurrences, and numerous tie-ins to the clinical and fiscal subsystems.
  Over 600K bytes and 20K lines of code (20% comments) manipulating 17 new database tables, with 40 design and implementation documents.
  (ColdFusion 5, IE-specific HTML/JavaScript, CSS, SQL, Perl)
• eBoat. Team-based analysis, design, framework, and coding of a 3-tier web application designed to eventually replace the entire suite of Echo client/server applications. eBoat ran under MSIE4+, Netscape4+, and Opera5.
  (ColdFusion 4.5, cross-browser HTML/JavaScript, CSS, SQL)
• Research of new web technologies and development of prototypes for web application frameworks and components.
  (Java/JSP/J2EE, ASP, Delphi, COM+/DCOM, .NET)
• CASP. Port (VB3 to VB6), enhancement, and y2k fixes for a suite of clinical service planners. Project manager and lead programmer.
  (Visual Basic 6)
• ITS (Batch, UCL, CSynch). Design and development of a suite of synchronization utilities for two health care databases with conflicting metadata. Complete analysis and design documentation, including entity relationship diagrams, for each project.
  (Visual Basic 5/6, Crystal Reports, UML)
• Structured SQL stored procedures and ad-hoc queries to meet claims and finance department reporting requirements.

QuickATM
(May 1993 - July 1997)

Company/Job Description

QuickATM was the leading supplier of interactive touchscreen information kiosks in U.S. airports. Since 1993, the network of roughly 100 airport and railway touchscreen information kiosks served over 7,000 travelers per day. The QuickAID web site provided comprehensive airport and travel information for more than thirty airports, and QuickAID Internet Stations provide email and web access to travelers at airports nationwide.

QuickATM was a small company; I had many roles simultaneously, including: senior software developer, network administrator, web developer, hardware troubleshooter, and graphic designer.

Project Details

• Designed, documented, and implemented the user database for the QuickAID Internet Stations, as well as the client/server interface to it. This database includes a fault-tolerant system for replication and propagation of the database between distributed servers (over TCP).
  (Perl under Linux)
• Proxima. Wrote a combination HTTP daemon and HTTP proxy server from the ground up. This server supports virtual hosting, caching, remapping, site and URL censoring, and was fully compliant with the HTTP/1.0 and CGI/1.1 IETF specifications.
  (Perl under Linux)
• QCall. Debugged, significantly enhanced, and maintained the QuickAID engine for touchscreen kiosks, and all supporting software, from the initial prototype version through its current version. This 24,000+ line C program was running on over one hundred kiosks at airports nationwide.
  (Watcom C and Microsoft C under DOS; screens designed in Multimedia ToolBook)
• Debugged, recoded, and enhanced the client software for the QuickAID Internet Stations. This program featured browser, telnet, and email functionality.
  (Visual C++ and Visual Basic under Windows NT4)
• Designed and implemented all back-end server support for the QuickAID Internet Stations, including: real-time usage monitoring programs, usage statistics, secure user authentication, encrypted credit card storage, and a credit card billing interface to ICVerify.
  (C and Perl CGI scripts under Linux)
• Designed the QuickAID and QuickRAIL web sites. This included page layout and design, scripts to convert Microsoft Access databases into HTML, and CGI scripts for real-time data extraction.
• Designed the Multimedia ToolBook book for constructing, maintaining, and exporting multi-screen, multi-level airport terminal maps.
• Other miscellaneous responsibilities included:
  - administering office servers (Novell Netware and Linux);
  - documenting software and operational procedures;
  - training and supervising the kiosk maintenance staff;
  - installing, maintaining, and debugging internal and field hardware;
  - creating internal office utilities.
