My job is to ease my client's life by making a polished and profitable iOS app. I can: • develop an effective, reliable and easy-to-support native iOS app from scratch; • fix, update, or complete your existing Objective-C / Swift / C++ code; • integrate various APIs and SDKs like Parse, Pushwoosh, RevMob, Xplode, Flurry, etc; • implement advanced web interaction models, like custom data synchronization.
