Android ROM Developer for Built-In App Feature Restriction Framework (with Remote Policy Control)
If You are looking for a top developer that will do anything it takes to find a solution to any problem then you have to hire ghulam. I had a customized software filter was made for a custom Android ROM and we initially had problems implementing it into a very lockdown ROM and the amount of time and effort ghulam put into my project was way above what I expected. I don't think there would be any other freelancer that would have put in the amount of time and effort like ghulam Did in order to make it work and find a solution. He is extremely detail-oriented and I was extremely extremely happy about hiring ghulam and If I ever have another project in the future like this I would definitely not think twice before hiring ghulam.
