One of the more complex applications I have worked on, Bandbooking is used by Prime Restaurants to manage their bandbookings.
Features it includes are: Shared band database, adaptive design, custom calendar, automatic facebook posts, integration with Primepubs.com live music page, multiple user support, recurring booking support.
I was responsible for all the front-end, and had a person taking care of the backend for me.
Technologies used were: Angular, PHP, Facebook API, and SQL.
Sorry but, you cannot look around.
