Rockstar🎓
Top SchoolSadiq Jaffer is an experienced research-focused software engineer and academic leader with 12 years in industry and research, currently an Assistant Research Professor and Bernstein Planetary Computing Fellow at the University of Cambridge. He blends deep systems expertise—demonstrated by low-level contributions to the core OCaml runtime and garbage collector—with practical product and startup experience as a former CEO and CTO who built high-throughput ad platforms and ML infrastructure. His background spans mobile robotics (PhD), real-time embedded systems, large-scale ad-serving, and performance engineering for ML systems, reflecting a rare mix of systems programming and applied machine learning. He has led technology teams and startups, and continues to run a consultancy focused on high-performance ML and benchmarking. Not obvious from titles alone is his hands-on work altering assembly and memory-management internals in a major functional language runtime, showing comfort with both algorithmic research and production-grade performance tuning. Based in Cambridge, he repeatedly bridges academic research and industry impact, shipping scalable systems and novel research.
