Summary
🤩
Rockstar🎓
Top SchoolChifeng Cai is a Principal Software Engineer with over 20 years building large-scale, high‑throughput distributed systems and more than a decade of technical leadership and engineering management experience. At Microsoft he architects and operates a production inference platform serving LLMs across 100K compute nodes and 138 billion requests per day with 99.9% SLA, and previously led teams that cut data ingestion latency from minutes to seconds for petabyte-scale pipelines. He blends deep systems and platform skills (C#, Go, Kubernetes, Kafka, Redis, Prometheus) with applied SRE practices—developing proactive repair bots and zero‑downtime patching across heterogeneous VM SKUs. A Certified Scrum Master and three‑time awardee for team contribution and quality, he is equally comfortable shaping high‑level architecture and writing the tooling that keeps services reliable. Not obvious from titles: he repeatedly delivers dramatic cost and latency optimizations (e.g., 35% compute savings on search captioning) while scaling platforms used by thousands of internal and external customers.
