Panagiotis Perlepes contributed to the snowplow/documentation and snowplow/snowplow-javascript-tracker repositories, focusing on feature development and technical documentation. He delivered enhancements such as client-side property validation and a new cookieExtensionService, replacing deprecated APIs while maintaining backward compatibility. His work included updating the Snowtype CLI for local development workflows and publishing comprehensive tutorials to streamline onboarding. Panagiotis modernized CI/CD pipelines by upgrading GitHub Actions runner images, improving build reliability and security. Using JavaScript, TypeScript, and YAML, he emphasized data quality, governance, and developer experience, demonstrating depth in API design, software refactoring, and technical writing across full stack environments.

May 2025 monthly summary: Delivered a key feature replacement of the deprecated idService with cookieExtensionService in the Snowplow JavaScript Tracker, with backward-compatible fallback logic to idService when the new service is not provided. Updated API surfaces, tests, and documentation to reflect the new service name, enabling a smoother migration path. Executed targeted documentation improvements across the repository to rename ID service to Cookie Extension service, and clarified the availability of the Event Specifications plugin (since v3.23) for Data Products created with the Media Web template. These changes reduce migration risk, improve developer understanding, and align with browser lifecycle considerations (Safari ITPS).
