MTV News was an iPhone and iPad application designed to wrap the content of www.mtv.com/news with a native navigation container and a single social feature. The client intercepted the inbound web content and modified the source code in transit to support a native navigation experience using the GoNative SDK. The user was encouraged to take screenshots of the content and share it with friends through many social network APIs. The client hired Crush & Lovely (http://crushlovely.com) to implement the design and Crush needed a subcontractor to develop the iOS client. The MTV team knew at the outset that their chosen solution was a temporary fix to a larger branding challenge, and the MTV News app was removed from the App Store in late 2017.

The development of MTV News was conducted by an internal project manager, external project manager, iOS developer, Android developer, and a backend web client team. The team followed an agile development process. Responsibilities included:

• Customizing the GoNative wrapper for MTV’s web content
• Adding an interface to screenshot the content; adding the social network sharing APIs for iMessage Email, Instagram, Facebook, Twitter, Pinterest, and WhatsApp
• Delivering pixel-perfect animation sequences for UI component transitions

Yarn was a cross platform photos service developed at the Samsung Accelerator in New York City. The product was designed to transfer the photos from storage such as iCloud, Dropbox, etc. into a proprietary analytical pipeline. The user was encouraged to tag photos with hashtags about people, places, and interests, and the Yarn application server would automatically, periodically return a collection of photos grouped together by topic. The goal of the work at the Accelerator was to integrate the service as a default in Samsung Nexus devices, and the first release was designed and built for iOS, Android, and web clients. The Yarn iOS application was released into production, with several subsequent maintenance releases, and roughly 5,000 users were accepted into the beta. The Accelerator did not choose to acquire the IP, and the client was eventually removed from the App Store. Apple’s native Photos client released an identical service shortly before Yarn was disbanded.

The development of Yarn was managed by a product owner, Chief Technology Officer, machine learning and back-end developer, front-end web developer, native iOS developer, native Android developer, remote iOS contractors, and a succession of UX designers and product consultants. The team followed an agile development process. The Accelerator required the product owner to present progress monthly to the executive team in order to continue funding for development. The remote iOS contractors were focused on delivering content for the presentation’s meeting while the in- house developer was focused on long term production code. Responsibilities included:

• Design and implementation of a network client to fetch photos from first-party and third-party repositories within foreground and background processes
• Design and implementation of a Model View, View Model design pattern
• Design and implementation of a parent/child CoreData model for fetching and storing assets and metadata
• Design and implementation of a gallery layout algorithm
• Implementation of a card-based memory feed, gallery presentation view, gallery editing view, collage editing view, photo tagging view, and other custom interfaces in auto-layout

Weather Whiskers and Smiley Central were designed by IAC’s Mindspark group, aka Ask Applications, to gather behavior tracking data on iOS usage. Smiley Central was a sticker app that sent custom Smileys through text messages and other channels. Weather Whiskers was a weather app that delivered the forecast with large photos of cats. Both clients implemented a custom behavior tracking analytics service used by Mindspark to track long term value against cost per acquisition. Mindspark needed an emergency fix in the in-app purchasing system before Christmas, and the work developed into a full-time role that ended in recruitment into a higher paying start-up environment at Beautified.

The development of Mindspark’s app relied on a product owner, project manager, two back-end engineers, a single native iOS engineer, and two designers. The team participated in daily standups and followed a strict agile development process documented in Atlassian’s JIRA and Confluence. Responsibilities included:

• Refactoring the iPhone client into a universal client
• Writing a wrapper for the custom behavior tracking system
• Improving the speed and transition of scrolling through views with large assets
• Bug fixing in-app purchasing crashes in legacy code
