My name is Martyn. I am currently a Computer Science Technical Lead in the Repair Analytics department at J.D. Power.

My role covers a variety of different areas:

This is a newer area of work, where I've been mainly focussing for just over a year, learning to use PySpark and Python to perform data engineering work inside Palantir Foundry.

Everything from configuring new instances, writing and managing multi billion row ETL processes and writing stored procedures to perform complex data analysis. Most of the time I'm trying convince SQL Server to do something it wasn't really designed to do, in as fast a way as possible!

One day, this could be writing front-end TypeScript code for a ASP.Net Web application and the next, coding high performance command line applications to process billion row CSV files or handling hundreds of millions of individual data files.

I'm part of the core team that manages the network and servers, so turn my hand to whatever situations arise.

I live in the UK, just outside of Rugby, with my wife and son and our dog, Bob and cat, Jasper.
