Hi,
I went through the brief and understand that you want to have "sidebar" module developed for your application. I'm knowledgeable in angular 2 and higher and can assist you to complete this task.
I'm a full-stack web developer specializing in .Net technology stack including typescript, angular 1.x/2 and higher, RxJS, angular material, bootstrap, etc and also knowledgeable in NODE.
Please send me a message so that we can discuss further about your project.
Cheers,
Swamy.
