Hello,
Hallo, das ist Ardi aus Hamburg. Danke für die Einladung :). Ich kann nur ein bisschen Deutsch sprechen. Ich werde auf Englisch weitermachen :)
For this project, we can work with both, mysqli or PDO mysql. The advantage of PDO is that it is usable with many databases, not only MySQL. About the XML interface for sure we can make code changes as well as UI changes. Waiting to discuss for more details in chat.
Other than technical aspects of the project, I can guarantee you commitment and hard work to get it done within time, periodical updates, communication with any means that we agree on, flexibility if project requirements need to change a bit, high efficiency, etc.
Please, consider this application seriously. In case you wonder why some people have more stars than me, the answer is: i have just joined this platform :)
Wish you the best of luck in this project, anyhow.
You can write to me anytime for any questions, I will respond at real time, except for my 6.5 hours of night sleep :)
In case you cannot contact me through chat here, you can mail me at: ardi at nordbit dot co
Best,
Ardi
