Siebel Expert (technical/functional) / Team Leader

Greater Paris Metropolitan Region

I'm currently working as freelancer consultant focused on Siebel CRM and OBIEE technologies administration, architecture and troubleshooting with no specific geographic limitation (currently Western Europe).
In my opinion, in order to solve a problem, there is no best system, no best software nor best people.
The only efficient way to succeed is to use the most effective part of each and find the most appropriate solution.
