What are some common challenges faced by Senior Python Flask Developers when working on large-scale applications?

Senior Python Flask Developers often encounter challenges such as managing complex codebases, ensuring scalability, and maintaining performance as applications grow. Integrating Flask with other technologies (like databases, caching systems, or third-party APIs) can introduce architectural complexities. Additionally, balancing rapid development with writing maintainable, well-tested code is crucial. Collaboration with frontend developers, DevOps, and QA teams is frequent, requiring strong communication and problem-solving skills.
