During September 2025, Juno Xiang focused on backend development for the parca-dev/parca repository, addressing a routing inconsistency between gRPC gateway and REST endpoints. Juno resolved this by aligning grpcWebMux with StripPrefix, ensuring that API requests were routed consistently regardless of protocol. This targeted fix improved client interoperability and reduced support overhead by providing a more stable API surface. The solution was implemented in Go, leveraging skills in API Gateway and gRPC, and included comprehensive tests for routing edge cases. Juno’s work demonstrated a methodical approach to backend reliability, addressing a nuanced server routing issue with depth and precision.
