FAQ
What do you need to start fixing my Next.js bugs?
To begin, I will need access to your code repository (such as GitHub, GitLab, or a ZIP file). Please also provide a live link to the website if possible, along with a brief description or screenshot of the exact bug, console warning, or hydration error you want me to resolve
How do you optimize my React website's performance and loading speed?
I perform a detailed diagnostic audit of your bundle sizes. I implement proven Next.js speed optimizations like dynamic imports (lazy loading), Next.js Image component optimization , eliminating rendering bottlenecks, and streamlining API or state-management routes
Can you resolve hydration errors and console warnings in Next.js?
Yes! Hydration errors are incredibly common in Next.js when there is a mismatch between the pre-rendered server HTML and the client's browser DOM. I will track down the conflicting code (such as dates, global window references, or browser hooks) and resolve it safely.
Do you offer a quick 24-hour delivery option for urgent bug fixes?
Yes, my Basic Package includes a guaranteed 24-hour delivery turnaround specifically for urgent React and Next.js bugs. If your website is down or throwing critical production errors, please message me immediately for prioritized help.
Will you respect the privacy of my custom repository and sign an NDA?
Absolutely. As a professional frontend developer, I treat your intellectual property with the highest standard of security. Your repository, database configurations, and API keys will never be shared with third parties. I am happy to sign an NDA if required.
