Worked on stabilizing session management in the PostHog/posthog-js-lite repository, focusing on the React Native SDK. Addressed a bug affecting the initialization of the currentSessionId to ensure accurate session tracking and improved reliability for mobile analytics. Refined the logging system by consolidating session replay logs behind a debug flag, which reduced unnecessary log noise in production environments and enhanced clarity during debugging sessions. Utilized TypeScript and JavaScript to implement these changes, applying SDK development best practices. The work contributed to more maintainable code and better production stability, while supporting efficient debugging workflows for teams using the PostHog JS Lite SDK.
