FAQ
What information or access do you need to start working?
To get started, I will need a clear description of the bug or issue, any relevant screenshots or error logs from the console, and access to your codebase (such as a GitHub repository or zip file). If the issue involves the backend or database, I may also need temporary access to your hosting server
Can you fix my bug or issue urgently?
Yes, absolutely! I understand that application downtime or broken features can harm your business. Please message me directly with the details of the issue before ordering, and I will let you know if I can deliver an emergency fix right away.
Do you offer revision support if the bug reappears?
Yes, I provide support post-delivery. If the specific issue we discussed returns or wasn't completely resolved, I will look into it and fix it at no extra cost to ensure everything works perfectly.
Can you work with complex MERN stack applications?
Yes! I specialize in the MERN stack (MongoDB, Express.js, React.js, Node.js) as well as Next.js. Whether it is a minor UI misalignment or a complex API integration/state management bug, I can debug and resolve it efficiently.
Will my code and credentials remain secure?
Your privacy and security are my top priorities. Any credentials, API keys, or proprietary code you share will be kept strictly confidential and used solely for troubleshooting your application. I highly recommend changing temporary passwords once the job is completed.
