I work on Flipkart's iOS App. We work extensively with technologies like Texture (AsyncDisplayKit), Realm and a bit of React Native, along with Apple's frameworks, in a mixed Objective-C + Swift codebase.
I like to spend time improving the performance and network characteristics of the app, to make it run better on older devices, and optimising for 2G/3G networks. Sometimes I work on in-house performance measurement dashboards using MeteorJS / Node.
In my spare time, I also work on build automation and distribution, using Xcode Server (previously Jenkins + fastlane).

• Built WatchDog, a real-time mobile apps monitoring dashboard, which hooks into the application at runtime, and plugs in to Xcode, to gather information about method run times, network calls, requests, latencies, data usage, main thread block events, and displays them on a Meteor Dashboard. The framework does all this without a single line of code intrusion in the host app. The dashboard also relates all these metrics in the context of Git branches, commits and tags, and helps track regressions and bugs early in the development cycle.
