FAQ
What is the main focus of this Gig?
This Gig is focused on fixing bugs, improving performance/optimization, and integrating small features into your existing MERN Stack (React, Node.js, MongoDB/PostgreSQL) application. I do not build entire applications from scratch here.
Why does the Basic Package start at $20?
My Basic Package is for quick, professional fixes (1-2 simple bugs) and guarantees experienced MERN expertise.
What information do you need from me to start fixing bugs?
To start immediately, I need 1. Access to your codebase (Git Repository), 2. Detailed description/screenshots of the bug, and 3. Instructions on how to reproduce the issue on my local system.
Can you fix both Frontend (React) and Backend (Node.js) issues?
Yes. I am a full-stack developer who specializes in the backend, so I can efficiently fix bugs in your React/Redux state management as well as your Node.js/Express API logic.
What is included in "Optimization"?
Optimization includes: refactoring unperformant code, setting up proper indexing in MongoDB/PostgreSQL, optimizing API response times, or improving Redux state logic. Please discuss your specific performance issue before ordering.
Do you offer support after the fix is delivered?
Yes. After the fix is delivered and accepted, I provide 5 days of free support to ensure the fix is working correctly in your environment.
