Summary
🤩
Rockstar🎓
Top SchoolKeqiu H is a seasoned software engineer and leader with 13 years of experience building large-scale AI training and serving infrastructure across LinkedIn, Databricks, and DeepMind. He led teams that scaled LinkedIn’s Hadoop/YARN clusters to 12K+ nodes and enabled training of billion-parameter models, then transitioned to building customer-facing AI serving platforms and multi-cloud serverless inference. Equally at home in mobile infra—creator of Bluepill that saved millions in iOS testing—and backend distributed systems—creator of TonY for TensorFlow on YARN—he blends systems engineering with product impact. An active open-source maintainer and PMC/tsc member (Ray, Horovod, Apache projects), he donates flagship projects to foundations and shapes community governance. Based in Sunnyvale with an MS from Columbia, he combines hands-on coding, hardware-software co-design, and scaling pragmatism to turn research and exabyte-scale data into reliable production ML platforms. A less obvious strength: he moves seamlessly between developer productivity wins (weekly iOS releases) and heavy-duty cluster orchestration, proving an ability to optimize both developer velocity and large-scale system efficiency.
