Biography

I'm a software consultant with Simple Machines, having consulted for Telstra and Health Combined. I previously worked with Analytics and Information at the Commonwealth Bank of Australia, building the ETL pipeline supporting their Customer Decisioning and Insights platform. I'm an experienced Scala developer, and have worked with Hadoop MapReduce, Scalding, Spark, Cassandra, Kafka, and a wide variety of other technology.

I previously completed a Ph.D. in Computer Science and a Bachelor of Computer and Mathematical Sciences (First Class Honours) at the University of Western Australia. My Ph.D. thesis was titled Logics for quantifying over information change and my honours thesis was titled Refinement Quantifiers for Logics of Belief and Knowledge, both supervised by Tim French and Rowan Davies. At UWA I participated in the Computer Science Students Club, competed in and later assisted in organising and training for the ACM ICPC at UWA, and taught as a laboratory demonstrator for databases, and data structures and algorithms courses.

In my free time I play video games, build Lego, and race bicycles.
