Dear Prospective Employer,

Let me take this opportunity to introduce myself and seek your assistance in
finding suitable employment. I am a graduate student specializing CAAD
(Computer- Aided Architectural Design) in the School of Architecture at The
Ohio State University, Columbus, Ohio. This is a unique program with a focus on
the exploration of electronic / computer media which may create a better
architecture. My course work at The Ohio State University involves many
computer science courses and CAAD courses.

I have been actively involved in developing CAD software for architectural
design/drafting applications, under the able guidance of Dr. Chris Yessios for
the past three years. I am very familiar with solid modeling systems and
graphic packages ( Actually I have developed my own solid/void modeling system
in Macintosh II environment. So I am very proud of my knowledge about CAD and
programming in C). I have demonstrated skills in graphics programming on the
Macintosh and Sun work station (UNIX) environments. Currently I am working on a
Masters thesis project which will result in the development of a CAAD system
with solid modeling/geometric reasoning capabilities.

Furtheremore, since I have diverse and unique academic background, I believe
that the uniqueness is going to help develop unique and creative CAD/ other
systems (I also have many ideas about CAD applications).

I am about to complete my Master's program. So I am deeply interested in
pursuing a career in your company. I firmly believe your company could benefit
from my expertise and solid background in CAD and solid modeling fields.

I would greatly appreciate if you could point me to the person(s) responsible
for hiring me, so I can discuss my interests in working with you.


Sincerely yours,

Jinwon Choi.
