Santa Stream is an iOS/Android app that streams live video from Santa's Village. I completed the app within a week by fixing many bugs and submitted the app for publication in time for the Christmas deadline. “After a not so great experience with a different developer, Derek has been a breath of fresh air. He's great to work with. I needed someone I could trust and knew what they were doing to finish an incomplete app. Derek did it professionally, on time and provided excellent communication. I look forward to future work with Derek.” –Jon @Santa Stream

Xenomia is an in-development online competitive multiplayer game. It is a hybrid of First-Person and Real-Time Strategy gameplay. Since it is built on the DOOM engine (yes, that DOOM engine!), an external launcher is used to provide a great experience for players. I am the sole software developer for the game, and so far I have implemented a fully-functional account system, chat server, matchmaking service and launcher that runs on both Windows 7 and Mac OS X 10.9.

MobilityAE (pre-release) is a high-end luxury ridesharing service using environmentally-friendly Teslas in Dubai. I implemented a real-time map that allows administrators to see and manage all of the active drivers (i.e. geolocation and tracking). I also built a feature that allows dispatchers to deploy a group of cars to one location. Using the Google Maps API, I implemented an Angular frontend to view streaming driver data.
