Abstract:

API design and implementation are skills that are usually treated as just parts of mastering an implementation language like Java. Poorly thought-out API decisions or APIs driven by implementation framework defaults can lead to maintainability, security, or performance problems that are hard to fix once the APIs are already in use.

In my talk, I will show real-world examples of APIs that work well at the beginning, but can be the source of unexpected problems later.
