Worked on enhancing the user recommendation system within the bluesky-social/atproto repository by introducing a recId field to the getSuggestedUsersSkeleton JSON schema. Focused on API development and JSON schema design, the approach aimed to support more robust user suggestions while maintaining compatibility with existing data flows. After evaluating the impact of this schema change, the update was rolled back to preserve product stability and prevent downstream disruption. This process demonstrated careful change management and a disciplined approach to feature deployment, utilizing JSON and schema design skills to balance innovation with reliability in a collaborative development environment.
