WORK HISTORY
Senior Software Engineer @New Relic
Portland, OR, US
Contributed to redesigning the distributed tracing pipeline that processes 1.2B+ spans/minute. Led architecture for Transaction Events and it\'s Thrift data model, conducted JMH performance benchmarking, and defined clear service ownership boundaries across the unified pipeline architecture.* Built the Attribute Change Analysis (bubbleUp) backend using statistical tests (G-test, two-proportion Z-test) so users can find trace attribute outliers, pinpoint slow or failing services, and debug across distributed systems.* Optimized query performance for trace and span query latency by 20–45% via parallel query chunking, time window batching, and coroutine based execution. Added intelligent trace waterfall caching (~84% faster on cache hits).* Contributed to Transaction Trace UI and Traces in APM Summaries, implemented custom pie-charts, CSV export, and batched time series fetching in the UI based on user scroll.* Shipped Preserve Trace feature using async Kafka flow, deduplication, and retention so users can revisit previously viewed traces.
