About
Jonathan Langley
Senior analytics and business intelligence professional with deep experience in Tableau, data visualisation and financial-services analytics.
Analytics that support better decisions
I have extensive experience delivering analytics and business intelligence solutions, including senior analytics roles in financial services. Most recently I was VP Tableau Developer in Compliance Data Analytics at Barclays.
That work has spanned dashboard development, visual analytics, compliance and risk analytics, BI governance and modernisation, and reporting rationalisation across financial services and other enterprise environments.
My strongest areas are Tableau, data visualisation and analytical dashboard design — turning complex information into reporting people can actually use to decide what to do next. I also develop in Power BI, including report design, semantic models, TMDL and DAX; the Haven Warranty Analytics project is the current evidence of that work.

Approach
How I approach analytics
Start with the decision
Understand the business question and the decision it feeds before choosing the output or the tool.
Clarity over complexity
Use analytical and visual hierarchy so the important information is easier to see and act on.
Use technology pragmatically
Adopt modern tools and AI where they improve analytical development, while keeping human judgement over requirements, metrics and outcomes.
