    • Led the development of an app (iOS/Mac/Android) using Objective-C, Swift, and Android SDK.
    • Led the development of a 3D weather maps system that beautifies weather map tiles on server and projects them through beautiful shaders on a 3D globe on a mobile app. I have customized an open source 3D engine to support it.
    • Developed a prediction system that predicts user location on a specific hour and customizes a non-intrusive weather alert using Python and Scikit-learn.
    • Led the development of a back-end server for the frontend apps serving weather information, weather maps and push notifications to hundreds of thousands of monthly active users using PHP, AWS and MySQL.
    • Developed a 2D game on iPhone using Cocos2d and extending it with 3D models support.

    EndTask Pro
    • Developed a tool that monitors running apps for any suspicious behavior, blocks the the suspicious action, and warns the user using low-level system hooks.
    • Built a generic tool that detects and blocks intrusive pop-up ads by monitoring user behavior without integrating with the browser.
    • Created and managed a small virtual team to help push this app to life—the app was later featured as an Editor's Pick on CNET.

  • Clear Day

    A line of weather products for iOS, Android, and Mac that altogether garnered more than 10 million users around the world, various awards, and coverage on a myriad of newspapers and TV networks. It lasted many months in the top-selling paid apps in the iOS App Store worldwide. It spawned the birth of a new style in the design of weather applications—an animated representation of the weather condition that was later implemented by top technology companies.
