During January 2026, Zimmra focused on backend development for the iOfficeAI/AionUi repository, addressing a critical authentication issue in MCP transports. By updating the TypeScript HTTP client to ensure transport headers, including authorization tokens, were consistently propagated to both StreamableHTTP and SSE transports, Zimmra resolved a persistent bug that previously caused header drops and authentication failures. The solution involved modifying request initialization logic to securely include all necessary headers, thereby stabilizing API integrations and reducing incident risk for downstream applications. This work demonstrated strong skills in API integration, secure header management, and debugging complex transport-layer interactions within a production environment.
