Portfolio

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

Santa Stream: Cross-Platform Video Streaming

BounceChat: iOS UI/UX Refresh

Custom Gravity Forms plugin enabling clients to enter all of the information required to build a custom app for BounceChat at bouncechat.com.

Implemented a major UI/UX overhaul on iOS client application. Architected and implemented web-based administrator tools for a template-driven app generator and remote configuration set up. Responded to rapid and shifting development requirements for several iOS apps as well as my own backend administrator consoles. Served as a core member of a small startup team performing various administrative, conceptual, and technical duties for which no specialist was present.

BounceChat: iOS App Automation Form

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.

Shipster is an on-demand shipping service that uses an Uber-like app to act as both a local courier and long-distance shipper.

As a sole frontend developer, I implemented a series of UI/UX enhancements to iOS app and handled customer support. I improved software architecture of iOS app and backend server infrastructure to ease maintenance. During that time I have increased the efficiency and functionality of Shipster's formidable realtime Agent deployment and tracking backend.

Shipster: Full Stack Development

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.

Convert complex Apple IPA Application to PWA (have source file)

*** WARNING TO ALL *** Paid initial milestone then a milestone for design (no functionality) (which was half the project cost) then Derek went missing and non contactable by myself nor freelancer, but can see he is viewing all private messages. Scammer. Do not use.
