During April 2026, this developer contributed to the airbytehq/airbyte repository by implementing the HubSpot V3 Lists API Memberships Stream, expanding the HubSpot integration to provide access to contact list membership data. The work involved integrating HubSpot’s API v3, developing a new data stream in Python, and ensuring robust unit testing. By enabling streaming access to list memberships, the update allowed customers to build more comprehensive list-level analytics and automations while improving data freshness. The feature was delivered through collaborative, co-authored development, demonstrating attention to code quality and effective teamwork within the Airbyte project’s established engineering practices.
