About

Data Scientist, Statistician, Developer. Functional Programmer.

These days I use Haskell, R, SQL and the Snowflake Data Cloud platform. In days gone by I was a C programmer, then a C++ programmer, and have dabbled in Python, Rust, and a few others. Then a Linux sysadmin working with bash, sed, awk etc. Also formerly an academic (Statistical Epidemiology at Leeds University UK). Currently a Data Engineer/Scientist.
