Work Terms

I am available Monday to Sunday, 24/7, for communication, project updates, and urgent support when needed.

I am open to both hourly and fixed-price/milestone-based projects. For hourly projects, my rate is $12/hour. I prefer clear weekly hour limits, task priorities, and regular progress updates. I can track time properly and share updates on completed work, pending tasks, and next steps.

For fixed-price projects, I prefer dividing the work into clear milestones such as project setup, UI development, API integration, testing, bug fixing, and deployment.

Before starting, I prefer to review the project requirements, design files, API documentation, existing codebase, project files, and required setup details. Once the scope is clear, I can provide a timeline, estimated hours, and delivery plan.

Payments should be handled only through the freelance platform’s official payment system. Communication can be done through platform chat, with scheduled calls when needed.

I focus on clean code, scalable architecture, responsive UI, performance optimization, and reliable delivery. Revisions are included within the agreed scope, and any additional work outside the original scope can be handled hourly or as a separate milestone.
