Being in this android arena for more than 6 years, I had build a number of android apps in different fields. Recent one was based on IOT. I had worked on from general android apps to R&D Apps in my career. So trust me with your work, also got perfect backup from tech personalities in this field.
Note Project Budget can be negotiated as per the system to be developed if you want, this what i bid is an avg rate accordingly. Thank You
