John is Founder and CEO of Windjammer Technologies, a Silicon Valley start-up. Windjammer's product is a plug-in accelerator for AWS EMR 6.x, GCP Dataproc 2.x, and Apache Spark 3.x that transparently accelerates query performance by 3x and cuts costs to 1/3rd. Prior to starting Windjammer, John was Vice President/Senior Fellow at SanDisk Corporation and Founder/Chairman of Schooner Information Technologies (acquired by SanDisk), where he led explorations and creation of flash-optimized databases. Prior to Schooner, John was director of Computer System Research at Sun Microsystems Laboratories where he led research teams in multi-core processors, scale-out architectures, and advanced high-performance computer systems. Prior to Sun, John was director of Computer Systems R&D at Hewlett Packard and a key member of the core team which put HP into the commercial computer business. John holds a Ph.D. in Computer Science from UCLA, Masters in Computer Science from Stanford University, and Masters in Mathematics from UCLA. John has numerous patents and publications.Partial list of patents:U.S. Patent No. 11,327,966 B1: Disaggregated query processing on data lakes based on pipelined, massively parallel, distributed native query execution on compute clusters utilizing precise, parallel, asynchronous shared storage repository access U.S. Patent No. 62/898,331, filed Sept. 10, 2019, Massively Parallel Processing with Precise Parallel Prefetching on Data Lake Cloud Object Stores​​Published Patent Application No. 2022/0277006 Disaggregated query processing utilizing precise, parallel, asynchronous shared storage repository access U.S. Patent No. 9,390,021 Efficient cache utilization in a tiered data structure U.S. Patent No.8,792,279 Architectures for data analytics using computational NAND memory U.S. Patent No.8,725,951 Efficient flash memory-based object store U.S. Patent No.8,677,055 Flexible way of specifying storage attributes in a flash memory-based object store U.S. Patent No.7,346,736 Selecting basis functions to form a regression model for cache performance
