Full Stack Developer Needed to Fix and Stabilize a Custom CRM Web Application

I recently built a custom CRM web application for my sales team using React and Node.js with heavy help from AI coding tools. It is meant to help the team manage leads deals customer records and follow ups from a single dashboard instead of juggling spreadsheets. The app mostly works but once the team started using it daily problems started showing up. Dashboards freeze randomly data does not sync properly between users login sessions drop unexpectedly and reports sometimes show numbers that do not match the actual records. It also does not behave well on phones and tablets which the sales team relies on constantly. I am looking for a full stack developer who can review the entire application find the root causes of these problems fix them properly and help me turn this into a stable tool my team can actually depend on: Overall performance and security Data sync and API reliability Works properly on both desktop and mobile. The ideal candidate is a genuine full stack developer with strong experience building and repairing CRM style web applications. You should be comfortable working with React Node.js APIs and databases and should also be confident reviewing and cleaning up code that was originally generated with the help of AI coding assistants. Someone who can act as a bit of an AI coding consultant and tell me what to keep and what to rebuild would be ideal. Clear communication is important since I would like regular updates and honest explanations throughout the project. When Applying Should include: 1. Your experience building or fixing CRM web applications. 2. Similar debugging or stabilization projects you have 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 your proposal with the word COMPASS Benefit : Ongoing long term project
