Worked on the ofkm/arcane repository to address authentication reliability in the Edge Tunnel Proxy, focusing on backend development and middleware design using Go. Delivered a targeted fix that injects agent token headers into proxy requests, resolving 401 errors caused by invalid session cookies and improving the authentication flow for edge tunnel clients. This approach ensured consistent token propagation and enhanced proxy stability, reducing failure modes and support incidents. The work improved observability of authentication behavior, enabling faster incident resolution. Emphasized API integration and robust session management, resulting in a more reliable experience for users interacting with the edge tunnel proxy infrastructure.
