Senior Programmer (Sub-contractor)

Sub-contractor assisting SAIC staff in the Department of Defense (DoD), CHCS platform conversion of all national and international MTF sites. Intersystems Cache was replacing Digital Standard MUMPs (DSM). The conversion involved modifications, installation, and removal of MUMPs routines, MUMPs Globals (databases), application menu structures, and device files. Successful HIPAA regulation test were necessary to receive the contract.

Confidential, Durham, NC

Programmer (Independent Contractor)

Worked with site's senior programmer on a project to integrate a newly acquired medical laboratory system into The LabCorp laboratory system. The accessioning schema was the major hurdle, requiring code research and modification for multiple programs to properly handle the different accessioning structures.

A proposed solution was initially dismissed by the site's senior programmer, however, it gained his acceptance when realizing the overwhelming challenge of modifying/testing dozens of routines. The accessioning issue could be resolved by using a “dual-indexed” Global which provided a pointer from a new accession number to the foreign accession number and a reverse pointer from the foreign accession number to the newly generated accession number used in the current laboratory system. This made it possible to enter either system's accessioning number (from either system) and retrieve the corresponding accessioning number to the other accessioning system. This provided an elegant solution as only the initial accessioning program would need modification to look up the correct accession number and pass that to all existing laboratory programs. These programs would not then need to be modified since they already worked within a well organized accessioning system.

Confidential, Winslow, AZ Programmer/System Analyst

Analyzed, developed, and debugged, MUMPs routines in the Resource and Patient Management System (RPMS) utilizing The InterSystems Cache Integrated Development Environment (IDE) on the client side (or “Cache Cube) of InterSystems Cache.

  • Rewrote the RPMS MUMPs Contract Health System (CHS) financial interface application to;
  • improve reliability
  • generate an error report for unknown debits and/or credits
  • designed to address generally accepted bookkeeping standards
  • Analyzed problems with the 835/837 claim interfaces between IHS, the banks, and The State of Arizona
  • installed RPMS patches into the live system
  • assisted RPMS programmers in Albuquerque, NM in debugging their RPMS programs.

Researched and developed services related to security policies for the Management Information System (MIS) department. Implemented and configured the Open Secure Shell (OpenSSH) service on The IBM AIX mainframe to assure secure communications with the client side PuTTY SSH on MS XP Pro workstations. Built a subnet network utilizing iptables to configure the gateway and firewall that would isolate the Test node and Development node on the subnet from the live, main network. A two-homed server running Red Hat Linux 8.0 acted as the gateway between the live network, two AIX test servers running Unix 5.2 (for server/client testing) and Windows XP workstations. Including the PuTTYAgent daemon in this configuration made it possible to eliminate the need for user passwords, telnet, ftp, rsh, rlogin, and rcp.

Handled administrative lead on the hardware and OS resources for the IBM AIX Unix servers: a two-node cluster utilizing HACMP for system fail over. Additionally, installed the AIX OS for an IBM pSeries model 620 (software application test machine), as well as an IBM pSeries model 520 (software development machine.)

Researched, implemented and configured ‘sudo’ on the IBM AIX live system to give users, vendors, and support staff secure, controlled access to certain ‘root’ Unix utilities/tools.
