During January 2026, David expanded the Heap Cloud destination in the segmentio/action-destinations repository to support GDPR and EU data residency requirements. He introduced a region enum and dynamic endpoint routing, allowing customer data to be directed to the appropriate EU endpoint based on user selection in the UI. His work included updating core actions such as trackEvent and identifyUser to leverage region-based routing, ensuring compliance and scalability for multi-region support. David implemented these features using Node.js and TypeScript, and added comprehensive unit tests to validate endpoint selection logic, demonstrating a focused approach to robust, maintainable full stack development.
