San Bruno, California, United States
Summary
🤩
Rockstar🎓
Top SchoolJuntao Li is a software engineer with 7 years of experience building high-performance distributed systems and applied AI, currently contributing to Google's Ads storage infrastructure from San Bruno. He blends a strong research background in computer vision and reinforcement learning—earned at Carnegie Mellon and Zhejiang University—with hands-on engineering experience at Splunk and SenseTime. Juntao has a track record of shipping impactful optimizations, from halving customer dashboard build time at Splunk to implementing large-scale timer and pop-consumption improvements in the widely used Apache RocketMQ project. His research produced practical wins too, including a traffic gesture recognition pipeline with a 89.7% accuracy and an OGTL reinforcement-learning scheme that dramatically cut training time. Equally comfortable in low-level distributed storage and ML model development, he often bridges the gap between prototype research and production-ready systems. Colleagues describe him as a pragmatic problem-solver who accelerates labeling and training workflows and roots solutions in measurable performance gains.
