Software Engineer specializing in telemetry infrastructure and cloud-scale data platforms.
United StatesWhat I'm looking for
I’m a Software Engineer specializing in telemetry infrastructure and data platforms, with 7+ years building cloud-scale telemetry systems and real-time engagement platforms. At Datadog, I architected unified telemetry ingestion processing trillions of daily data points using Go, Python, and Kotlin services on Kubernetes with AWS MSK and SQS.
I focus heavily on reliability and speed: I re-architected the internal gRPC service mesh with custom least-loaded connection pooling, cutting end-to-end event processing latency by 40% while maintaining 99.9%+ availability. I also improved deployment velocity by moving to multiple daily deploys and reduced MTTD by 60% using OpenTelemetry instrumentation.
I partner closely with Data Science and Product to turn telemetry needs into shipped features, and I mentor engineers while driving architecture via RFCs and async-first collaboration. I’ve also built an AI-assisted debugging workflow (Cursor Rules and a Copilot extension) that reduced MTTR for common ingestion issues by 45% and onboarding time by 25%.
Experience
Work history, roles, and key accomplishments
Architected Datadog unified telemetry ingestion components processing trillions of daily metrics, traces, and logs using Go/Python/Kotlin microservices on Kubernetes with AWS MSK Kafka and SQS decoupling. Reduced end-to-end event processing latency by 40%, improved reliability to 99.9%+, cut cloud compute costs by 25%, and increased deployment frequency while reducing MTTD by 60%.
Designed and built Peloton real-time leaderboard and social engagement microservices serving 6+ million members with low-latency updates and analytics-ready historical data. Handled 100K+ requests per second with under 50ms p95 latency using Redis/Memcached, deployed event-driven pipelines processing tens of millions of daily events, and reduced infrastructure costs by 30%.
