Summary
🤩
Rockstar🎓
Top SchoolDavid Rosa is a software engineer with six years of experience building low-latency systems for electronic trading and consumer-scale services, currently focused on high-frequency options infrastructure at Susquehanna. He progressed rapidly at Amazon—designing systems used by over 10M monthly active users and earning a promotion in 18 months—and has a strong quantitative background from roles in ML research, risk analytics at Deloitte, and autonomous vehicle perception. Holding dual undergraduate degrees in Mathematics and Industrial Engineering and pursuing advanced degrees in AI and mathematics, he blends rigorous theory with production engineering. Known as a proactive mentor and interviewer, he pairs a goal-oriented mindset with a talent for motivating teams to deliver practical, analytically driven solutions. An unusual thread through his career is sustained cross-domain work: from LiDAR perception to semantic caches for LLMs to sub-millisecond trading signals.
