VIMOV

Led the development of an app (iOS/Mac/Android) using Objective-C, Swift, and Android SDK.

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.

Founder | Developer

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.

Experience

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.
