We are looking for an analyst with experience in business requirements analysis as well as software architecture. We need to have coded a complex financial application, for which we need first to describe requirements as much as possible. the candidate will not be required to be coding, although the capacity to design UI would be a plus. the candidate should be experienced, open minded, with a proven background. Candidate within a team would pe preferred, this is not a absolute prerequisite. Knowledge of french would be a plus. We will provide the "coder" with notes, which are ideas that need to be structured. We expect the coder to ask a zillion questions. The final product will not be technically complex, but the number of parameters, business rules, etc, make for the need for such a document. We expect the bidder to provide with a description like this: - I will output a document with XX pages and following structure -......................... -....................;......... - etc - I will do it in X days/weeks - We will work like this (work method, questions:answers, daily reporting..) - and I will charge that much it is POSSIBLE to use a pay-per-time scheme, rather than a pay per deliverable. If things are not clear, you are more than wellcome to ask for further informations. Thank you
