Worked on the Shubhamsaboo/adk-python repository to enhance the reliability of session management in backend systems. Addressed a bug in the InMemorySessionService by correcting the after_timestamp filtering logic within the get_session method, ensuring that session events at or after the specified timestamp are accurately included. This fix resolved a slicing issue that previously impacted session data integrity. Developed a comprehensive test suite in Python to cover various configurations, including num_recent_events and after_timestamp combinations, to prevent future regressions. The work demonstrated a methodical approach to backend development, session management, and testing, resulting in more robust and accurate analytics capabilities.
