Worked on the block/elasticgraph repository to enhance HTTP request handling by refining how Content-Type headers are parsed in Ruby on Rails APIs. Addressed a bug where valid requests with additional Content-Type parameters were incorrectly rejected with HTTP 400 errors, improving reliability for clients with varied header formats. The solution involved isolating and updating the backend logic to ignore extraneous parameters, aligning with established header parsing practices. This targeted fix reduced edge-case failures and support incidents, demonstrating a methodical approach to input validation and robust API development. Utilized Ruby and backend development skills to deliver a low-risk, maintainable improvement to production systems.
