Bryan O'Sullivan’s Summary
Extensive background in distributed, networked and high-performance software development for many platforms, primarily Linux. Experience spans range from Linux kernel internals and device drivers through compilers; scientific computing on large clusters; functional programming and Haskell; GUI toolkits; and Java web application servers. Strong background in open source, performance, clustering and distributed systems. I've written one well-regarded book on a leading-edge technical subject, and am working on another. I'm interested in designing and leading the development of top-quality software.
