Small Business TaskNest Web Application Bug Fixing Expert Needed

I recently built a small business management web application called TaskNest CRM using Cloud Code.It is designed for service-based businesses such as cleaning companies, car detailing businesses, plumbers, electricians, HVAC companies, landscapers, and other small businesses that need to manage CRUD operations from one platform. The application is approximately 90% complete and most of the core functionality is already working.However, once I started using it with real business data it crashes all the time and when I try to fix it all I know is that it is simply beyond my technical knowledge to fix on my own.Things like random crashes, login problems, broken CRUD functionality, API errors, inconsistent data, slow performance, and responsive design issues are making the platform unreliable. I'm looking for someone who can go through the entire codebase and perform a complete technical audit, identify the root causes of these issues fix these problems properly, optimize everything, and help me turn it into a stable, production ready business application that I can confidently use without worrying about bugs: Overall performance & security Database and API reliability Works properly on both desktop and mobile. The Ideal candidate should have solid full-stack development experience and is genuinely good at debugging complex applications especially ones built using AI or Cloud Code.You should be comfortable working with React, Node.js, APIs, databases, and authentication systems, and be able to improve the existing architecture rather than just patching problems temporarily.Good communication is also important since I'd like regular updates and clear explanations throughout the project. When Applying Should include: 1. Your experience fixing complex web application bugs. 2. Similar debugging or stabilization projects you've completed. 3. Your estimated timeline. 4. Your approach to auditing and resolving a large existing codebase. 5. Any recommendations you would make after reviewing the project. 6. Start off your proposal with the word “ BONJOUR “ Benefit : Ongoing long term project
