Gingersnap is an iOS app aimed at connecting grandparents and children through personalized stories, play, activities, and adventure.

I was the lead on the development of two apps, one for grandchildren and one for grandparents.

Jardine Motors

Jardine Motors is an interactive sales tool that car dealerships use to up-sell insurance packages on car sales with a 3D showroom car highlighting the benefits of each package to the customer. The iPad app integrates with a sophisticated tracking system so each sales rep can be tracked on sales and performance, as well as fully complying with regulated insurance laws.

Tax Apps
These apps formed a tax information platform for a forward-thinking accounting firm that saw a need in the market for a customizable app that could be individually branded and resold to tax firms around the world. The app features news feeds, push notifications, tax calculators, car expense tracking, multiple currencies, and contact support, all updatable from a web server in real time for a fully flexible platform.

I've managed the development of both the iOS and Android apps and developed the iOS app over the past 2 years.
This is a curated music playlist service that integrates into Spotify to manage and identify popular playlists. Since working on the rewrite of the iOS app and managing the Android App rewrite, the company has since been sold to Warner Brothers.

Hidden Newcastle
Hidden Newcastle is a location-based guide that allows users to explore the strange and forgotten stories of Newcastle’s past. Using region triggers and notifications to alert users to interesting stories nearby, Hidden Newcastle inspires users to explore the city.

The app uncovers the real people who once lived and worked in the city of Newcastle upon Tyne through video, audio, images, and text.

Through exploration into identity and community, the group curated 12 questions that were chosen for their ability to evoke meaningful responses. These questions were then used to interview people in Walker, where each individual answer was recorded and stored as an online hidden video. The questions themselves were immortalized as metal plaques, each designed by one of the students on the project. The questions and corresponding answers were linked together by an invisible bond, traceable only by the accompanying WLKR app.

Next Metro

A collection of offline metro timetables for iOS and Apple Watch.
