Work Experience
Co-Founder | Technical Lead
2008 - PRESENT
VIMOV
- 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.
- Shared in the co-founding and operating a startup and expanding it to a 30-employee software company.

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.

Project History
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.
iSimulate
iSimulate allows developers to simulate multi-touch events, the accelerometer, compass and GPS, on the iOS simulator by wirelessly sending these events from an iPhone, iPad, or iPod Touch to an SDK running on the simulator.
Method for Presenting Weather Data | Patent
