What difficulties did you face in completing your last project?

When completing the last project, the following difficulties often arise:

• Integration with external services: sometimes APIs change or are unstable, requiring additional debugging time.
• Performance optimization: identifying bottlenecks and fixing them before release.
• Testing and bug fixes: discovering and fixing errors that only manifest under real conditions.
• Coordination with the team and client: clarifying requirements and making final adjustments.

For example, in my last project, there was an issue with asynchronous data loading, which sometimes caused the interface to freeze. I had to profile the application, optimize requests, and add error handling to ensure smooth operation.
