Hello, I can work on your Angular projects. I have already worked on angular and developed some merchandizing, ecommerce and educational web apps and also dashboards. I can work on different angular versions from Angularjs to Angular11.
I am also fullstack developer, if you will have anything from backend then it will be of no problem. just leave me a message and i will get back to you.
thank you.
