About

I build distributed, declarative database management engines that enable modern applications such as AI, machine learning, business analytics, and graph data processing. My background spans hardcore theoretical database foundations to large scale system building and optimization, spanning query optimization, distributed evaluation, parallelization, logical and physical plan generation, data partitioning, and distributed execution. I am interested in simplifying Big Data management, and increasing the productivity of data science and machine learning teams by providing powerful, expressive, and performant Big Data APIs and languages.
