Jeff Bonwick is a Software Engineer, most notable for leading the team that developed the ZFS file system.[1] He was a Sun Fellow and later a Vice President at Sun Microsystems and then a Senior Software Architect at Oracle until his departure from the company on 30 September 2010.[2] In 2010 he founded DSSD together with Mike Shapiro and Bill Moore. The company is now a division of EMC Corporation.[3][4]
Bonwick's other work includes the slab allocator,[5] an object-caching kernel memory allocator, and the LZJB compression algorithm.
Bonwick published a blog which details the development of ZFS.[6]
