Hello,
I come up with an experience of 7+ years in developing application for MAC, I was working for an organisation where Apple is our client. Through out my 7 years of experience I have worked on Apple internal projects using Objective - C and Swift. Currently I resigned to my job and working as a freelancer , hope my skill and experiences benefits you. Kindly, let me know more details about your application, whether its a new app to develop or any issue with an existing app. I am ready to do any kind of fixing or even ready to create a new application too.
Thanks,
Nayome
