Martin Squires

Director of Data, Insight & Analytics at HomeServe
Lee headed up the analysis team on a number of projects for me at M&S Money. Lee definitely ticks all the "techie" boxes you'd expect but what set Lee apart was what else he brought. As well as the core analytical "stuff", Lee was a great source of ideas & creativity and brought a genuine desire to deliver the best project the team possibly could. Plus he's genuinely a fun bloke to work with.

Matt Bennathan

Country Manager, Data Cloud UK at Oracle
Lee combines very strong analytical skills with a personable nature. He's commercially focused and has the useful ability to explain complex analytical solutions in straight-forward, plain English, highlighting the real world benefits accordingly. I would recommend Lee without hesitation.
