Highlight Projects
Traffic Management Software
Creative studio teams (dealing usually with marketing campaigns, artwork, digital adverts, banners, product packaging etc.) currently using either a range of disparate systems (e.g. Microsoft Project, spreadsheets, trackers, etc.) that don’t talk to each other and are admin heavy and time intensive or a project management system that kind of does what they want but not really. I proposed building a web application that combines the features and functions of these existing systems that work, into one solution that provides a traffic management system for managing a studio.
