As a Contract Sr Python Developer, one of the most common challenges is quickly understanding and adapting to legacy codebases and existing system architectures.

Effective communication with the in-house development team and stakeholders is crucial to clarify requirements, resolve ambiguities, and ensure smooth interoperability.
