SKILLS
ABOUT JONATHAN LANGLEY
Data and analytics professional with 20+ years’ experience working in complex, highly regulated environments, primarily within financial services.My focus is on turning messy, fragmented data into clear, usable insight that supports better decision-making. I’ve spent much of my career working with SQL, data modelling, and BI tools to build scalable analytics solutions that are widely adopted and relied upon by business teams.At Barclays and in previous roles, I’ve worked closely with senior stakeholders, technology teams, and control functions to understand real business problems and translate them into meaningful analytics. This has included improving visibility across risk and compliance, standardising reporting, and helping teams move away from manual processes towards more consistent, self-service solutions.Alongside delivery, I’ve been involved in setting standards around dashboard design, data quality, and governance, with a focus on making analytics more usable, reliable, and aligned to how the business actually operates.I’m increasingly interested in how AI and automation can enhance analytics, particularly where strong data foundations and governance are in place. My focus is on applying these approaches in a practical way to improve how insight is generated and used in day-to-day decision-making.
