What the Freelancer needs to start the work

Information Required to Start Backend Development

To deliver a secure, scalable, and high-quality backend solution, I require the following from the client before starting development:

• Clear project goals and feature requirements
• User roles, permissions, and workflow details
• API requirements and third-party integrations
• Database preference and data structure (if available)
• Authentication method (login, JWT, OAuth, etc.)
• Hosting/server access (VPS, cPanel, cloud)

• Existing codebase or documentation (if applicable)
• Timeline, milestones, and budget confirmation
• Preferred communication and feedback process

Providing these details ensures smooth development, accurate delivery, and minimal revisions.
