Andrew Werner is a seasoned software engineer with 12 years of experience building and scaling distributed systems and databases, currently a Member of Technical Staff based in New York. He has deep back-end and database expertise demonstrated by substantive contributions to CockroachDB, where he refactored index management, improved multi-region behavior, and fixed complex deletion and cursor-edge cases in a widely used cloud-native SQL database. His career spans startups and infrastructure teams—from co-founding Data Ex Machina (acquired) and leading engineering at Upthere to senior roles at Datadog and Western Digital—blending hands-on coding with product and operational sensibilities. An investor and builder, he moves comfortably between founding ventures and contributing to large open-source projects, favoring pragmatic refactors that yield measurable reliability and performance gains. He holds a BS in Computer Science from Princeton and brings a pattern-oriented approach to systems design informed by both product-stage constraints and production-scale demands.
