Fix & Enhance Our Crypto Trading Webapp

We need a skilled developer to review our cryptotrading webapp and ultimately fix and improve it. The frontend is built in NextJS(at the moment), we're using MongoDB for data storage, and AWS to host our Python application. The project requires exceptional knowledge in: NodeJS, NextJS, MongoDB, Python, CCXT, API, Websockets and an expert level understanding of the API docs of the following exchanges: Bybit, Bitget and OKX.

Key requirements:
- Fixing backend functionality and API issues
- Implementing frontend fixes in the user interface
- Enhancing Error Handling, Data Synchronization, Connection Stability, Security and AWS efficiency
- Reviewing code, implementing environmental variables.
- Enhancing user authentication and session management mechanisms

At the end of the project, we would need a tutorial on how to set everything up on ourselves.

Skills and experience:
- Extensive experience with NodeJS, NextJS and MongoDB
- Deep understanding of Python, CCXT, API and Websockets
- Expert level knowledge of the exchanges: Bybit, Bitget and OKX API docs
- Strong debugging and code review skills
- Ability to create user-friendly interface enhancements
- Experience with creating tutorial or guidance documentation or 1on1 sessions

The project needs to be completed within 1-2 months. The final delivery should include a tutorial in the format of whatever the developer prefers.
