Rockstar🎓
Top SchoolNisan Haramati is a founder and principal distributed systems engineer with 13 years building resilient, large-scale real-time data platforms across companies like Snowflake, NVIDIA, Netflix, and Wallaroo Labs. He specializes in real-time ingestion, observability, and automation—designing systems that prioritize correctness, data quality, and long-term maintainability while delivering core value early. At Snowflake he led observability for a global services platform handling trillions of events per day, and at NVIDIA he drove unified fleet management and geospatial data automation for large-scale AI infrastructure. A core contributor to Wallaroo’s distributed stream processing ecosystem, he blends hands-on backend and DevOps work with formal and empirical verification techniques to harden systems under chaos. He pairs his technical depth (physics/math background) with a habit of engaging product and operational stakeholders directly, which helps turn high-level objectives into production-ready, auditable solutions. Outside work he pursues physics, cooking, and community engagement—reflecting a practical curiosity that often leads to elegant, pragmatic engineering choices.
