Dear Sirs and Madams,

I am responding to your advertisement on your European Homepage for the position of Operations Manager at the Corporate Head Office in Amsterdam.

The described position and responsibilities are very appealing to me. I have been able to gather five years of work experience in various economic branches, mainly in Sales departements. My position as Event Manager with (xx) in (xx) gave great insights into market research, creative planning, budget management and post-event analysis. 

Through the sales position within the recently opened (xx) Hotel in (xx), I have a considerable amount of experience with customers, including CEO level, to show for. Being part of a newly created sales team with unlimited opportunities supplied me with a very positive attitude towards my work, consantly focussing on ways to improve present operations.

I am currently working as International Sales Manager at (xx). My responsibilities include handling all contracts with foreign customers, developing new business areas, aquiring clients from overseas, aswell as buying and selling of fuels. Futhermore the opportunity to build a department for e-commerce from scratch, which is turning out to be a great success after just one year, granted me experience in adminstrative and managerial tasks.
I strive to merge as many attributes as possible into a productive and constructive work method. Operating in various environments and jobs, in different countries and with multi-national colleagues has allowed me to study, adopt and incur various mentalities of working. 

My aim to relocate to the Netherlands is funded in the fact, that I highly rate the Dutch way of working. Over the years business relations with Dutch contractors and suppliers have certainly been the most pleasant, aswell as being successful. Further taking my Irish origin into account, the close vicintiy of the North Sea is an extra treat. 

Challenging tasks, unlimited horizons and ultimately the possibility to prosper are essentially what I expect in a position, hopefully as the newest member of the (xx) family.
