Dear mastercodebr,
I hope this message finds you well. My name is Christopher, and I have over 4 years of experience in PHP, Website Design, Graphic Design, HTML, and MySQL. I have carefully read your project requirements and I am confident that I can deliver this project with perfection.
I understand that you need a web-based system for advanced data analysis, with the ability to handle basic data management tasks. The user interface design should be intuitive and user-friendly. I am proficient in these skills and have prior experience in designing similar systems.
I have noticed that you have mentioned your own database and an API for querying data. I can create a username and password panel for normal customers, with different roles such as administrator, seller, and end customer. The administrator will have the ability to create sales users and end customers, while the seller user can create end customers.
If you have any questions or would like to discuss further details, please feel free to connect with me in the chat. I am available and ready to assist you.
Thank you for considering my proposal. I look forward to working with you on this project.
Best regards,
Christopher
