Developed configurable HTTP client support for the HTTPTarget component in the Azure/PyRIT repository, enabling users to pass additional keyword arguments to httpx.AsyncClient for advanced configuration of timeouts and SSL verification. Leveraged Python and asynchronous I/O to enhance the flexibility and reliability of outbound HTTP calls, reducing the risk of misconfiguration and supporting future extensibility. Employed test-driven development to ensure that argument propagation to the HTTP client functioned as intended, with comprehensive tests validating the new feature. Focused on API integration and full stack development, the work improved both security and maintainability without introducing new bugs during the period.
