My Process
First, I review your requirements, design files, API documentation, existing codebase, and project files. After that, I provide a clear development plan, timeline, and estimated hours or fixed project scope.
For larger projects, I prefer working in a series of milestones, such as project setup, UI development, API integration, testing, bug fixing, and deployment.I focus on building mobile apps that are clean, stable, 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.
