⚠ CRITICAL_ERRORS.log

[ERROR_100]: The main challenge was implementing real-time messaging between users. Using WebSocket for chat ensured instant communication, but it was tricky to handle user authentication and connection persistence. I overcame this by using auth middleware to securely manage WebSocket connections.
[ERROR_101]: With large amounts of data (jobs, proposals, users, messages), optimizing queries was a challenge. Using Prisma ORM allowed me to fine-tune queries, improve performance, and handle complex relations between users, projects, and proposals efficiently.
[ERROR_102]: Implementing a solid role-based access control system (client vs. freelancer) required ensuring that users could only access resources relevant to their roles. This was achieved through JWT authentication and custom role middleware.
[ERROR_103]: Integrating Cashfree Payments posed challenges, especially when implementing features like partial payments, refunds, and transaction validation. I handled this by thoroughly reviewing their documentation and implementing secure payment gateways.
[ERROR_104]: Storing images securely and ensuring the app scales was another hurdle. I integrated Cloudinary API to handle images efficiently, ensuring that uploaded files are optimized, stored securely, and linked to appropriate profiles and projects.
