  • OpenStore iOS Applications

    The OpenStore marketing platform allows clients to connect with their customers wherever they go with branded mobile apps for iOS, Android, and BlackBerry.

    The applications have a very flexible UI and can be customized remotely without an app update. Many different features, such as games, a route planner, digital coupons, location finders, feedback forms and iBeacons, can be turned on or off and adjusted remotely.

    I worked on the iOS apps from October 2010 to September 2015.

  • iBeacon Detection and Noise Reduction Library for iOS

    I developed a private library for the detection, smoothing, and filtering of iBeacons.

    It includes filtering to reduce the number of iBeacon alerts and smoothing to minimize the noise which is always present when working with radio signals.
