Hello,
I have read your project description that you want to develop marketplace platform app for buyers and sellers like Blue Cart.
I have 6 years of experienced on mobile application (Android ) and App admin with development web services where admin can manage the app from back end.
I have developed the TAXI apps, google map , Event App, Jab Potal App,Restaurant App,Dating App,Social chat with video calling and other apps with clients need .
I would approach your project by starting with wire frames and getting the design completed, before starting the actual development phase. Regarding your project if you have any reference or if you have already created a doc then please share with me so I can check and proceed in right momentum As concern for my skills please take a look on my past work
Please share more details to check and discuss .
Looking forward with more details
