Dear Sir/Madam,
please let me introduce myself briefly. Fifteen years dealing with information technology, I am mostly familiar with fields of web development and system and network operations. My main responsibility is the complete, iterative design, planning, specification and management of the whole IT infrastucture at several midsize companies.
I manage several web servers which mostly use nginx. On some servers they are operating also as a reverse proxy, serving static files via nginx and other stuff (e.g. PHP scripts) via apache for instance. I have experience in setting up rewrite rules in nginx with regular expressions, so I'm sure that I can solve your problem easily.
Having any questions please don't hesitate to contact me, I'll be glad to answer them. I'm looking forward to work with you.
Kind regards,
Robert.
