Developed and delivered key observability enhancements for the threatgrid/ctia repository by implementing OpenTelemetry middleware for HTTP route span instrumentation in Clojure. Focused on backend and middleware development, the work introduced a route-table matching system executed outside the routing chain to ensure the http.route attribute is set for all responses, including error cases like 401. Addressed routing edge cases by normalizing URIs and supporting ANY routes, improving accuracy and reliability of telemetry data. Enhanced code architecture by relocating integration points, expanding test coverage, and introducing test helpers, resulting in safer deployments and more effective incident triage through accurate, non-intrusive instrumentation.
