1. **Fluent Builder Pattern**: `CurlRequest` uses method chaining for configuration
2. **Factory Pattern**: `Curl` class provides static factory methods for each HTTP method
3. **Resource Management**: `CurlResponse` implements `Closeable` for try-with-resources
4. **Async Support**: Both synchronous (`executeSync()`) and asynchronous (`execute()`) execution modes
