Worked on integrating the posthog-rrweb package into the PostHog/posthog-js monorepo, focusing on automating the release flow and improving maintainability for the JavaScript stack. Leveraged JavaScript and TypeScript to align seven rrweb packages under a unified publish process using changesets, eliminating the previous two-step release. Updated CI/CD pipelines and dependency management tooling, including pnpm and turbo, to support the new monorepo structure. Ensured runtime parity by maintaining byte-identical recorder bundles and addressed test flakiness and docker build reliability. This work streamlined development workflows, reduced release friction, and provided clearer ownership for rrweb packages within the monorepo environment.
