About
Jonathan Langley
Senior analytics and business intelligence professional specialising in Tableau, Power BI, 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. That work has spanned dashboard development, visual analytics, compliance and risk analytics, BI governance and modernisation.
My strongest areas are Tableau, Power BI, data visualisation and analytical dashboard design — turning complex information into reporting people can actually use to decide what to do next.

How I approach analytics
Start with the decision
Understand the business question and intended decision before choosing the output.
Clarity over complexity
Use analytical and visual hierarchy to make the important information easier to see and act on.
Use technology pragmatically
Adopt modern tools and AI where they improve the analytical development process, while retaining human judgement over requirements, metrics and outcomes.
Current focus
I am continuing to develop work across Power BI and Tableau while exploring how AI-assisted development, source-controlled BI and analytical product thinking can improve analytics delivery.
