Ok here is the whole letter.
if there is something that makes your teeth grind let me know.
Dear Sir, Madam,}
\vspace{1cm}
I have seen on the APEC website that you are offering a position in system administration.\\
During my masters, PhD and last year’s post-doctoral position, I have developped a broad range of computationnal skills. My background went from chemistry to computational chemistry, code development and system administration, and I have gained considerable experience in several programming languages and system administration.\\
Furthermore, during my PhD at the university of Southampton, I was in charge of the system administration for my research group. As such I had to update and maintain several workstations and a beowulf cluster. I had to ensure that my co-workers' requirements for informatic tools, including software, compilers and libraries, were dealt with as promptly and as accurately as possible. I also managed my research project, the teaching labs and my system administration tasks in an autonomous manner. My research project was to implement a specific algorithm in an existing software.\\
Furthermore, I feel I would be an asset to your company and I am eager to work hard to make the most of the position you are offering. Feel free to let me know if you need further details, I will get back to you at my earliest.\\
Yours sincerely,
