Professional Experience
|
|
1982 - 1987
Systems Programmer
Arvin Industries
Columbus, Indiana
|
Primary responsibilities:
- support of an MVS assembly language system that controlled EDI transmissions
between Arvin and its customers (General Motors, Ford, etc.)
- installation and support of IBM Network Control Program
- installation and support of various third party MVS products such
as FDR
- capacity planning tool installation and support (IBM Service Level
Reporter)
Most important contribution was the development of the data communications
components of an automated system that monitored transmission of inventory
updates to customers. The system eliminated manual intervention for failed
transmissions and enabled automated retry and logging of transmission
activity. The system helped Arvin meet customer demand for Just In Time
inventory shipment notification.

1987 - 1992
Systems Programmer
Ivy Tech State College
Indianapolis, Indiana
|
Primary responsibilities:
- installation and support of all MVS/XA systems software, third party
software, CICS and NCP on a 4381 mainframe
- configuration and support of a multiple SNA domain network using VTAM
CDRM/CDRSC and NCP Gateway features on MVS and VM systems
Contributions:
- Technical planning and management of mainframe computer and network
systems during a week-long data center remodeling event. During this
event, I planned and implemented the operation of the MVS/XA, CICS,
and NCP systems from a disaster recovery center in Chicago. Within a
week of the return to the data center, implemented a migration from
4381 to 3090 mainframe and new version of MVS. All of this activity
took place within two weeks of fiscal year end processing, making project
planning and execution critical.
- Technical planning and implementation of the MVS and network components
of a migration from DOS/VSE to MVS/XA.

June 2000 - current
(as of May 2002)
Director of Systems Programming and Web Development
Ivy Tech State College
Indianapolis, Indiana
|
Primary responsibilities:
- management of IBM OS/390 mainframe systems programming (administrative
computing)
- management of Oracle Database Administration (adminstrative computing)
- hands-on systems programming on OS/390, Solaris, Linux and Windows
2000 / NT
- planning and development of inhouse administrative web application
based on java servlet, EJB, and relational database technologies
Contributions:
- design of administrative reporting servlet. Development platform is
Linux / Tomcat / Oracle 8i. Test and production platform is Solaris
/ Tomcat / Oracle 8i. I am the designer and primary developer on the
project. The applications consists of 23 different servlets coordinated
by a dispatcher servlet. The application uses session management, stores
queries in java object format for later reuse and editing, and allows
users to output data in HTML tables, Excel, or Adobe PDF. Translation
of JDBC result sets to JDOM XML Documents to Adobe PDF output done using
JDOM, Apache Xerces, Xalan and FOP. See java
development notes and database
notes for details.
- redesign (ongoing) of administrative reporting servlet to use Enterprise
Javabeans on Orion J2EE server. Project began in March 2002. Notes are
here.
- planning and cost analysis of various mainframe upgrade options to
meet increased resource demand (due to web application access) and provide
new functionality (OS390 Unix Systems Services functions, Linux for
S/390, etc.)
- investigation (ongoing) of cost savings and availability improvements
by consolidating Linux servers on mainframe using Linux for S/390
- development of security lockdown procedures for NT Server development
platforms (registry updates, ACL updates, Tripwire for NT implementation,
etc.).
- investigation and planning for SSL-based TN3270 access and OSPF routing
using VIPA on OS390 2.10. See sanitized notes
for details.
