Steps for completing your project
After purchasing the project, send requirements so Ahmed can start the project.
Delivery time starts when Ahmed receives requirements from you.
Ahmed works on your project following the steps below.
Revisions may occur after the delivery date.
Architecture and Design
Once the requirements are clear, the next step is to design the architecture of the backend system. This involves selecting the appropriate technologies, frameworks, and libraries to use as well as designing the database schema and defining the APIs
Development
With the architecture and design in place, the actual development of the backend system can begin. This involves writing code to implement the functionalities and features defined in the requirements and design phase
