Summary
👤
Senior🎓
Top SchoolKevin B is a Senior Data Scientist with eight years of experience turning product and business questions into scalable, production-ready analytics and ML systems. He has led data initiatives across startups and large companies—most recently at Atlassian and Quantcast—designing company-wide success metrics, automating forecasting and lift experiments, and operating pipelines that handle terabyte-to-petabyte scale data. Comfortable both coding and collaborating with executives, he translates statistical rigor into sales, marketing, and product impact (including multi-million dollar revenue modeling and automation that eliminated manual work). Kevin publishes data science insights on Medium and combines experimentation, causal inference, and strong engineering practices (Airflow, Spark, Docker, Kubernetes) to ship reliable data products. A less obvious strength: he frequently sits between engineering and leadership to institutionalize data trust and benchmark product performance for investor-facing storytelling.
