Dear Madam/Sir,

In response to your advertisement in Workopolis/Monster for an

engineer/developer/scientist position, I am enclosing my resume.

My academic achievements are in the fields of image

processing/reconstruction, medical systems (CT/PET/SPECT/MEG/MRI), signal

processing and radar/satellite telecommunication systems. My engineering

achievements are in the fields of navigation and communication

(GPS/GSM/GIS) of automobiles, the lithography of computer chips, and

wireless modems and embedded micro systems. My mathematical background is

in the field of simulation and numerical calculation. My software

development skills are with C/C51/C++/C#, GPU/Cuda, Java/J2EE,

IDL/Matlab/Maple and TCL/TK, Perl, Ruby, Python, SQL, Pascal, FORTRAN,

VTK/ITK, IPP. I am familiar with Windows 98/2000/XP systems, and more

specialized at UNIX environments (Aix, Linux, Solaris, OSF/1, Ultrix). I

would like to contribute to your company.

Besides, I have also strong background in mechanics and high frequency

electronics.

Thank you for your consideration. I am looking forward to hearing from you

soon. You may reach me at my cell phone 416-***-****) or home phone (416

223 0320) to schedule an interview. The word format of this letter and my

resume are attached.

Sincerely Yours
