Data Mastery

Data Mastery is a data consultancy based in the Belfast and Dublin, helping organisations transform how they collect, model, and leverage data. We specialise in designing and delivering modern analytics solutions built on Azure, Microsoft Fabric and Power BI, enabling business users to make confident, data-informed decisions. Our approach is deeply consultative: we embed ourselves within client teams to understand business goals and challenges, then craft custom ELT pipelines, semantic models, and reporting solutions tailored to their needs. Whether it’s setting up enterprise-grade data platforms or training teams to self-serve with Power BI, we make data more accessible, trustworthy, and actionable. With a blend of technical expertise and real-world business acumen, we help clients unlock the full value of their data—across industries such as mining, retail, finance, and professional services.
