Node JS \ Fix my site issue

I require assistance debugging and resolving an issue impacting functionality on a website built using the Node.js platform. The site has recently begun experiencing intermittent errors preventing certain pages and forms from loading correctly. A skilled Node developer is needed to inspect the codebase and deployment environment, identify the root cause of the problem, and implement an effective solution. Experience with debugging Node.js applications in production environments is essential. This is an urgent requirement as the ongoing site errors are negatively impacting the user experience and business operations. The successful candidate will have a strong portfolio demonstrating expertise in Node maintenance, troubleshooting complex coding problems, and optimizing performance. Please provide your hourly rate and anticipated timeline to complete this debugging project if you feel you have the qualifications needed to resolve the issue.
