Bryntum Scheduler & Kanban

Description

We need an EXPERT in creating a Scheduler and a Kanban using the Bryntum controls.
Please note the word EXPERT. If you are just a casual developer or have to learn the API then please DO NOT respond.
The controls will be used in an .NET MVC (razor views) application.
We are looking for a proper programmer so that if an appointment is being deleted an alert message shows prior to deleting, if an appointment is being created without a title an laert shows so on and so forth. i,e a SEASONED professional otherwise it will only result in us refusing your work and wasting both of our times.Thanks.
