A senior software engineer with 19 years of experience in iOS and cross-platform C++ programming.
Worked for a number of outsourcing and product companies before becoming an independent contractor.
On mobile, I mostly developed native and hybrid fintech, lifestyle, and utility apps using keychain, WebKit, location services, augmented reality and other features of iOS.
My C++ experience is even more diverse: from computational software to web services to specific hardware integration.
I can also do some web frontend.
