Hi,
I have been developing software for more than 10 years. The vast majority of software I have written has been for Windows Mobile and Windows CE devices. The applications I have written for mobile devices connect back to a variety of back-ends from SQL Server to IP21 to things like UNISYS mainframes.
I am new on Freelancer, but what you require is something that I have a lot of experience in. Please feel free to ask should you require any more information from me. Also, please let me know more of the details of exactly what you require. If it is something I cannot do, I will let you know. If it is, I will be able to compile a professional plan for the way forward.
Thank you for reading this.
