Dear Sir or Madam:

I have ten years experience in the full life cycle of software development
including the analysis, design, code, and test of various software systems.
These systems include launch vehicles, spacecraft checkout, Space Shuttle
experiments, ground control stations, and large system simulations.

Many times during my career, received commendations for my performance from my 
supervisors. I have authored such documents as Software Requirement Specifica-
tions, Software Design Documents, User's Manuals, and Proposals. Most of the 
documents followed applicable standards as required by the customer such as
MIL-STD-2167A. I have instructed personnel in the use of microcomputers,
software engineering methodologies and various application software programs.

Enclosed you will find my resume. A more detailed work history follows
containing my individual assignments, including my responsibilities along with
the corresponding programming languages and hardware used.


				Sincerely yours,


				Timothy D. Clay

Supporting the effort to replace the on board avionics of the Titan Space Launch
Vehicles. Responsible for and lead of five engineers for the design of the 
flight software performing the system built in test, preflight initialization, 
and the flight navigation, guidance and controls. Utilizing Cadre's Teamwork 
CASE environment. Software requirements, design development and test performed 
to MIL-STD-2167A standards. The flight processor uses the MIL-STD-1750A software
architecture. The system interfaces with the ground with a MIL-STD-422 interface
and sends telemetry via a MIL-STD-1553B data bus. (Development system: Hewlett 
Packard HP9000 (UNIX), Programming language: Ada)

June 1989 - March 1990 Titan Scientific Software

Coordinated and supported the effort to rewrite the Modularized System 
Scientific Simulation (MSSS) software package (6 degree of freedom Titan boost 
simulation) to move to new operating systems and machines. (Development systems:
Control Data Cyber mainframe (NOS,NOS/VE), Sun Workstations (UNIX), Programming 
language: FORTRAN 77)

Sept. 1987 - May 1989 Commercial Titan Launch Vehicles

Supported all activities for Commercial Titan flight software including 
requirements, development, compilation, verification (unit test), flight load 
generation and release. This included flight software, mission parameter loads
