My Process
First, I review your project requirements, API requirements, database structure, existing backend, project files, and required setup details. After that, I provide a clear development plan, estimated hours, timeline, and delivery approach. For larger projects, I prefer working in a series of milestones, such as project setup, database design, API development, authentication, integration, testing, bug fixing, and deployment.
I focus on building backend systems that are secure, fast, scalable, easy to maintain, and ready for real users.
Please share your project requirements before starting so I can review the scope and suggest the best approach.
