Worked on enhancing data quality and trace accuracy across the SigNoz/signoz-otel-collector and SigNoz/signoz repositories, focusing on backend development using Go and SQL. Developed a feature to improve http_host derivation by leveraging attributes like net.peer.name and url.full, which streamlined data modeling and enabled the deprecation of the external_http_url attribute. Addressed a bug in SigNoz/signoz by refining SQL queries with the FINAL modifier to ensure correct time range aggregation for traces sharing the same trace_id. Coordinated changes across repositories to maintain traceability, demonstrating skills in database management, attribute-based derivation, and cross-repository collaboration for instrumentation improvements.
