Worked on the RTXteam/RTX repository to enhance API and schema stability by updating OpenAPI YAML files for compatibility with newer Biolink Model versions. Focused on eliminating schema drift and preventing integration issues, the work involved precise modifications to YAML-based OpenAPI specifications, ensuring downstream consumers could access the latest knowledge graph features without disruption. Leveraged skills in API development and OpenAPI Specification to maintain a clean, auditable change history, supporting predictable rollbacks. The approach prioritized minimal risk by isolating changes to YAML files, aligning the project with evolving Biolink standards while preserving data integrity and facilitating future feature development.
