About

Most mid-sized businesses are sitting on a goldmine of data but struggle to turn it into real business value. I help companies unlock that potential with clear, actionable data strategies. At Reservoir, we work with businesses between £20-50M in revenue that have outgrown spreadsheets and need a structured data approach. Using the Microsoft data stack (Power BI, Data Factory, Dataverse), I help teams clean and centralise their data and create dashboards that drive action. With over 8 years of experience in data and business consultancy, I've seen firsthand how mid-sized businesses to large enterprises struggle to get value from their data. I founded Reservoir to bridge that gap, helping companies move from messy reports to structured, scalable insights. My process starts with understanding your business goals, building a comprehensive data strategy, identifying the right KPIs, and designing semantic models that power effective dashboards. Instead of overwhelming teams with complex data, I focus on practical solutions that drive immediate impact. If you're ready to move beyond Excel and build a data strategy that drives real business results, let’s connect. Drop me a message, and let’s chat.
