Steps for completing your project
After purchasing the project, send requirements so Hasnain can start the project.
Delivery time starts when Hasnain receives requirements from you.
Hasnain works on your project following the steps below.
Revisions may occur after the delivery date.
Step 1: Discovery & Requirements
We'll discuss your idea, business goals, target audience, and required features. If you already have wireframes, Figma designs, or reference websites, we'll review them together and define the project scope.
Step 2: Planning & Architecture
I'll create the technical architecture, define the database structure, choose the best technologies, and break the project into milestones. This ensures the MVP is scalable and maintainable from day one.
