Dear Sir or Madam:

I am writing to you in replay to your software engineer position as an

embedded firmware Engineer in your company.

I am an accomplished software engineer with over 20 years work experience

in the area of embedded system programming and software development. I

would appreciate consideration for employment in this position.

I am very strong in one chip assembly language that HEX code file convert

to assembly file and modify it. I did it over 20 years. I have many idea

for any project and very strong in design.

My innovative and successful career has centered on designing,

implementing, testing and optimizing

real-time control software, in C and Assembly language. Please refer to my

resume for further detailed information.

I believe that my knowledge of hardware, electronic theory and application,

experience of working on

control system, small-signal electronics design and troubleshooting will be

of great valuable to your

company.

I have been working as a embedded design engineer in battery Technology

INC. (USA). I have been working as a core software engineer in SEJIN

Electron INC. (South Korea), and have experience with technical writing and

presentation for specifications and device introductions. I am a team

player, I am self-motivated, organized and hardworking but I also can be a

good team player when necessary. I am committed to using my knowledge and

skills for my employer.
