PROFILE

Sam Wright

Worked on backend observability and instrumentation for distributed systems, focusing on Java and Scala agent development. Contributed to the alibaba/loongsuite-java-agent repository by enhancing Pekko HTTP server instrumentation, refactoring context management to ensure accurate span lifecycle during request timeouts, and improving route name reporting for better trace accuracy. In the open-telemetry/opentelemetry-java-instrumentation repository, delivered a feature that introduced per-request context isolation for Akka HTTP instrumentation, preventing cross-request context leakage and improving telemetry reliability. Leveraged technologies such as Akka, Pekko, OpenTelemetry, and Byte Buddy, with a strong emphasis on robust testing and maintainable, well-documented code changes.

March 2025 monthly summary for alibaba/loongsuite-java-agent: Delivered reliability and observability enhancements for Pekko-based HTTP instrumentation. Fixed Pekko HTTP Server Timeout Span Handling Bug to ensure proper span lifecycle during request timeouts, including context management refactor and updated tests. Implemented Pekko HTTP Server Route Name Reporting Enhancement to accurately capture and report route names by removing outdated path concatenation instrumentation and introducing a route state wrapper to preserve correct trace naming on path prefixes and nested routes. These changes improve trace accuracy, root-cause analysis, and monitoring dashboards, reducing MTTR and increasing confidence in distributed tracing. All changes were implemented with focused commits 11b59d017c12e4e7980aade03b4c14fe9ce23cc8 and c096540523a17972af60635539e7e616294c5bf7.
