While at CELF Creative in 2014 I developed an Enterprise Sales App for a large (multi-billion dollar), global, publicly traded company.
The app is for iPad. It allowed the sales team to create orders from the app, with access to their full product catalogue. It handled a complex set of business rules relating to an approval system for orders.
I was the sole iOS developer working on the project (the app was for iOS and web). I worked closely with the client to define the requirements and to design the app.
The app was a great success and is currently being used by the company in the UK.
