Summary
👤
Senior🎓
Top SchoolRyan Bressler is a staff machine learning engineer with 17 years of experience applying math-first research to high-impact products, currently leading content understanding, model research, and core relevance work at Reddit. He has a strong track record translating novel statistical and spectral methods—from survival analyses for long-term retention to graph and deep learning approaches—into production recommendation systems that move key metrics. Previously he scaled ML-driven investing at a Y Combinator-backed fund, growing assets from $1M to over $1.5B while building low-latency serving and a large research team. His early work in cancer genomics produced open-source tools and publications, and he founded Hillmap, the first web tool for avalanche terrain overlay used in safety courses. Based in Hamilton, Montana, he blends academic rigor with product-first engineering and a taste for outdoor stewardship through climber coalition leadership.
