Paystik is a suite of two iOS applications that allow merchants to accept orders from users' devices. The customer app also takes care of payment via the stored credit card. System works in near real-time through a cloud based service Pusher with no separate backend (apart from the database of products).

Both of the iOS apps were designed and programmed by me, I also built a simple RESTful API for the database of products/merchants. All-in-all the service makes use of about 6 different cloud based services, minimizing any need for scaling.

Developer of a small todo app called Cues. Cues relies on attaching notifications to locations around us and reminding them to the user when they are near them.
