Mentally Friendly, London, UK

iOS, Swift

  • Developed a hardware abstraction layer which handled state and communication with 3 bluetooth peripherals simultanely
  • Developed the onboarding process, which included discovery and configuration of hardware
  • Developed UI for setting preferences on the air pump, motorized base, and sensor strips
  • Integrated an SDK which handled communication with sensor strips (for monitoring heart and sleep disturbances)

  • Worked with SDK developers to identify bugs and API design issues

House Seven, 2015 July

House Seven is an application in the digital space for Soho House members

thumbnail
Mentally Friendly, London, UK

iOS, Objective-C

  • Soho House is a private members’ club for those in the film, media and creative industries) members
  • The app allows members to book events and screenings, view exclusive content, and access information about the various locations, wherever they are
  • Spotify sponsored an integration which required similar functionality to their own app, however they do not provide common UI elements to re-use, so a particular task I did with this project is to build a Spotify-like player
  • Other tasks included rebuilding the entire client-side authentication scheme, and updating / fixing parts of the application when new iOS releases changed APIs
  • Work on this project was started and paused numerous times throughout my time with MF. I partnered with a couple of other developers who had contributed to the app, but most of the work was done individually as other developers were resourced on other projects

  • Developed much of the core architecture and flagship features for Thumbtack's 2 iOS applications
  • Taught experienced developers coming from a web background how to be productive on iOS, explaining the idioms and tools
  • As the team grew (about 8 iOS devs, 4 server devs), I played a key role in making technical decisions around application architecture, tooling, and workflow, helping to keep our team as a whole productive and making it easier to bring new developers on board
