Hello.
My name Vitaly, I'm from Ukraine.
I have a good experience in Oracle databases and XML. It's commonly used for transferring the data among software systems.
Unfortunately, I'm not so familiar with Fidelio CRM. Just googled it. If I'm not mistaken, It's software for hotel business. Sorry, my profile in IT area. But I worked with many applications, and all required information can be taken from database easily.
Ready for chat here, on this site, or by telephone, Skype or Viber.
Best regards.
