Worked on the Shopify/hydrogen repository to deliver comprehensive API release notes and changelog documentation for the Storefront API and Customer Account API, focusing on the 2026-01 release. The work emphasized clear communication of breaking changes and improvements, such as updates to the CLI lockfile, to support developer upgrade paths and release readiness. Leveraged skills in API management, documentation, and version control, using JSON as the primary language for structuring release information. The approach aligned documentation with the project’s release cadence, aiming to reduce upgrade friction, improve onboarding, and enhance the overall developer experience through more transparent and accessible release processes.
