• Yahoo Answers Now app*
• The app was used to ask questions, create rich answers with images, and comment on those answers. The app used MVVM architecture. My responsibilities:
• Set up swagger for documenting API and generating boilerplate model and API code (which uses Retrofit over OkHttp, RxJava/RxAndroid for various asynchronous processing).
• Build the rich answer rendering experience by splitting it into sub-entities and rendering them one at a time so that each could get recycled.
• Rendering SDK*
• Rendering SDK is part of an entire system developed to support dynamic UIs. The UI is defined as layouts using the CSS flex-box algorithm on a card creator tool. The layout is converted into JSON and sent to the client, which is used to generate native UI widgets. The data-binding information is defined as a moustache template bound at runtime, the UI is styled, and the content is shown. The system has three components - rendering SDK, card creator tool and layout JSON serving backend. I worked on building the android rendering SDK:
• Worked on SDK architecture and design extensively
• I created the spec to support card rendering from various rendering engines in a single stream.
• The first card renders time was less than 100 ms.
• Aviate Launcher*
• Aviate was an app launcher showing relevant daily information through cards. My responsibilities include performance benchmarking and improvements:
• Build a performance dashboard by measuring key metrics like memory usage (PSS), FPS, APK file size, and cold start time.
• Improved cold start-up time by up to 60% for low-end devices by pushing out triggering services/sensors until UI becomes responsive. I benchmarked cold-start time by configuring varying thread counts for thread pools on various devices with various cores and came up with a common processor-multiplying factor, which optimally works for all sorts of devices.
• Build cricket cards to show live match scores, upcoming games and completed game results.

• Advertisement SDK for Native Apps*
• The Ad SDK was used for rendering ads in Yahoo! native apps like Mail, Sports, and Fantasy sports, to name a few. The Ad SDK could render images, JavaScript-based banners, and full-page JavaScript interstitial ads. Since the Ads SDK was IAB MRAID (Mobile Rich Media Ad Interface Definitions) complaint, it could render ads that could expand/close, open a landing page and support creatives by most media houses.
• Implementation of AD SDK involves using multi-threaded programming for pre-fetching ads from various ad servers in the background, caching it, rendering it when the app requires and tracking it.
