Based on the requirements, I will create a document that includes all of the features that I will develop as well as an estimated time frame.

The client will receive a competitive Django backend solution that will be optimized based on the business model and project type specified.

Based on the client's needs, a relational (PostgreSQL, MySQL, MSSQL) / non-relational (MongoDB) database will be fully integrated into the backend service.

After the website and all of its components are completed, I will assist the customer in recommending hosting services and deployment platforms like AWS, Digital Ocean, or GCP

I provide comprehensive version control solutions based on GIT and popular sites such as GitHub, GitLab, and Bitbucket. This ensures that clients' software development processes are improved through effective code management, collaborative development, and streamlined project tracking.

If the expected number of users/requests per second is very high, it will be required to scale backend services / optimize database query speed, apply caching methods, optimize database structure, and enable the use of several servers at the same time.
