Angular node js application

I am looking for an experienced Angular Node.js and MariaDB application developer to create an application with user authentication and authorization. The application should have a moderate level of user interaction, and should have a user-friendly design. This application should be able to handle multiple concurrent users and provide real-time data streaming, data visualization and analytics. If you have experience developing similar applications, know how to use a variety of methods, frameworks and platforms, then please submit an offer. Let me know your skills, relevant experience and portfolio. I'm looking forward to seeing your ideas and suggestions.
