Worked on the modelcontextprotocol/go-sdk repository to enhance the reliability of JSON loading in OAuth flows by addressing a parsing issue with HTTP content-type headers. Focused on backend development using Go, the work involved updating the JSON loader to robustly handle content-type headers that include parameters, such as charset specifications, in compliance with RFC standards. This defensive approach to HTTP header parsing eliminated failures when integrating with real-world OAuth endpoints, resulting in more stable client integrations and smoother deployments. The solution demonstrated skills in API development and backend reliability, directly reducing support incidents related to content-type mismatches in production environments.
