Worked on the graphql-hive/gateway repository to address a critical issue affecting real-time data reliability. Focused on stabilizing Server-Sent Events by redesigning the JSON parsing logic, the developer implemented a line-based parsing approach in TypeScript to prevent misinterpretation of payloads containing literal 'data:' substrings. This targeted bug fix eliminated a class of parsing errors that previously led to runtime failures in streaming dashboards and alerts. By improving the robustness of SSE handling, the work enhanced platform stability and reduced the risk of customer-impacting outages. The solution was delivered with a clear, testable approach, leveraging full stack development and testing skills.
