role
I designed, built, deployed, and developed an MVC web application hosted in Azure for a company of a friend of mine.
MVC and Razor C#, with JavaScript, HTML5, and JQuery front end, and ADO.NET backend with an SQL Database stored in Azure. For a company based in Reading with very limited carparking spaces. They wanted an application that would allow users to log on and book a car parking space on a date, between 2 times. This would also allow all spaces booked by a particular user, or all spaces booked on a particular date to be shown.
● Met with the customer and gathered their requirements to develop an application that could be built in time and would meet their available budget.
● Setup of Azure environment from scratch, making sure that the correct resources were bought that matched their requirements.
● Built backend SQL database with tables, relationships, and stored procedures in the on-site database and then migrated the database into Azure.
● Built MVC application that is hosted in Azure as a WebApp.
