// about me
18 years of data.
Built to go further.
Data manager, analyst, and independent builder — working at the intersection of business intelligence and modern software development.
Mario
Data Manager & Analyst · Freelance Developer
Newcastle-under-Lyme, UK
My career began in market and competitor analysis, progressed through pricing strategy and business intelligence coordination, and has focused for the past several years on energy data for hospitality businesses across the UK. Day-to-day: SQL Server, Power BI, and DAX — building dashboards, data models, and reporting systems that give clients a clear picture of their energy consumption and costs.
Beyond employment, I build independently. Four live products — Nexus Energy Dashboard, NutriPlan, SiteReport, and CVlifter — all designed, developed, and deployed end-to-end. This reflects a deliberate direction: toward independent, client-direct work where I own the problem from business requirement through to deployed solution.
BSc (Hons) Computer Science, University of Roehampton. Open to freelance data projects, dashboard builds, and technical consultancy.
