About

Statistician, Data Scientist/Engineer, Developer. Functional Programmer.

Feel free to connect with me on LinkedIn: https://www.linkedin.com/in/roblongleeds/

These days I mostly use R, Python, SQL, SAS, the Snowflake Data Cloud platform, and Haskell (whenever I get the chance). In days gone by I was a C programmer, then a C++ programmer, and have dabbled in 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).
