Rockstar🎓
Top SchoolSunny Klair is a Senior Engineering Manager based in New York with a decade of experience building observability, networking, and cloud-cost platforms at Datadog. He moved up from senior engineer to manager while contributing hands-on to core open-source work like the Datadog Agent—adding eBPF-based network tracing, improving log scrubbing, and tuning system-probe performance. His background spans high-scale services across SoundCloud, Twitter, Microsoft, and AWS internships, giving him deep expertise in distributed systems and monitoring. Known for blending people leadership with low-level engineering, he still ships production-grade backend and DevOps improvements himself.
