About

Software engineer by chance. And now when I’m into it why to be just naive. Developing iOS app was easy route to get access of Apple ecosystem and that’s how I’m an iOS developer. Built around 4 apps out of which two are from scratch, all are on app store for different organisation in Swift and Objective-C. Worked on the RxSwift, Combine, SwiftUI, CoreData in the recent codebase. Developed app using Async await Code from Swift 5.5 is cherry on the top to use with combine to make codebase readable and Organised. # forever_learner
