FAQ
What type of website bugs can you fix?
I can debug and fix a wide range of frontend and backend issues. This includes React components, Node.js server crashes, JavaScript logic errors, Express.js middleware issues, REST API integration errors, MongoDB database connection problems, responsive CSS/HTML layout issues, and browser console er
Do you fix both frontend and backend issues?
Yes, as a full-stack MERN stack developer, I handle both frontend and backend debugging. I am highly proficient in JavaScript, React, Node.js, Express, and databases, allowing me to trace an error from the user interface all the way back to the server and fix it seamlessly.
Should I contact you before placing an order?
Yes, please message me before placing an order. Because every code script and error is unique, reviewing your specific website bug, console warning, or repository beforehand allows me to accurately estimate the timeline and offer you the most cost-effective custom order.
Can you fix urgent website errors quickly?
Yes! If your production app is down or you are facing a critical deadline, I can prioritize your project. I offer extra fast delivery options to fix urgent React, Node.js, or JavaScript errors safely and efficiently without breaking your existing codebase.
Can you fix API and database connection errors?
Absolutely. I specialize in troubleshooting broken REST APIs, third-party API integrations, webhook errors, and database issues involving MongoDB, mongoose schemas, or SQL databases. I will ensure your data flows correctly between your frontend and backend.
Do I need to provide full access to my entire source code?
To debug and fix your app, I will typically need access to the relevant code files or repository (GitHub/GitLab), or temporary access to your hosting server. If you prefer, we can also do a live debugging session via screen share to maintain your privacy.
Will the fix break other features on my MERN stack website?
No. I write clean, maintainable code and test the solution thoroughly before delivery. My goal is to fix the root cause of the current React or Node.js bug without causing any regression issues or disrupting your website's existing functionality.
