Thanks for considering my bid.
I am a Computer Engineering graduate with 12+ years of experience, currently working independently, primarily on Android/web solutions.
I have read your requirements and confident of providing a professional, bug-free solution. As I understand it, you need an Android app (to be distributed to vendors) and an in-house app for your internal use by staff. The in-house solution can be either an android app or a browser-based web app. Also, there needs to be access control for different operations, eg people should see vendors assigned to them only, dispatch/sales engineer can access the whole data (to view which jobs are approved), only administrator can adding new staff members etc. My suggestion would be a mysql db with php server for data, native android app for vendors and a mobile-friendly website for internal use; but I am open to suggestions. I will provide a demo in 10 days and a final delivery will be made based on your test comments/suggestions. I will provide free 3 months post-delivery support to fix any issues found during field use.
I hope we can start working soon.
Thanks & regards,
