Hello there! My name is Muhaimin and I'm a professional with extensive experience in online SharePoint, web front-end programming, web design and more. I understand that you are looking for someone to create a project page on Microsoft SharePoint for you. You need the project page to include task tracking features and private permissions must be enabled. You have an existing platform to work off of as well.
I am confident that I can provide the best solution for this project. With my expertise in HTML, SharePoint and related technologies such as security measures and user interface design, I believe I can deliver a successful outcome that meets your needs. Moreover, I am willing to take into account any creative suggestions from you that would make the project run more smoothly or faster than normal.
