Hi,
Something challenging on your side, I believe not many will be able to do it :). Here am I Aadil Quadri expert n Front End development with Angularjs 1/2/4/5 and Java script. Well worth in writing my own components such as the tree, drag n drop, graph and much more to go.
I have checked your requirements and I want to work on your task. I am expert in developing the Front-End application with Angularjs, 2/4/5, HTML, Bootstrap, REST API interaction, UI Design and development. I will provide you good project structure and clean code with a proper review. For more discussion, we can have a conversation on Upwork.
You can share your contact details and I will discuss the Project details with as per your requirements. I am open to work on challenging tasks and other freelancers if needed.
I have worked on the role and permission-based Angular projects which required different pages to be loaded according to the permissions received from the backend APIs be it from Spring Security, Firebase or any other. Implementing Superuser, User and Admin role-based application within the single project is one amongst my expertise and that's what will play a major time-saving role in your work. I also have experience with AWS and cloud so I won't have any issue with API integration.
