## About

I turn messy data into decisions that stick\. With 3\+ years as a Power BI Developer and BI Analyst at Tata Consultancy Services, I've built end\-to\-end reporting solutions that real teams depend on from cutting report query times by 40% for 300\+ users, to migrating legacy Excel packs into governed Power BI dashboards that saved 60% in manual prep time\. My work sits at the intersection of data engineering and business storytelling\. I design star schema models, write complex DAX, manage Power BI Service governance, and translate what finance, underwriting, and operations teams actually need into dashboards they actually use\. I don't just hand over a report I make sure it answers the right question\. Before BI, I spent a year in L2/L3 application and data support, which gave me a strong foundation in production systems, SQL\-based root cause analysis, and data quality skills that make me a better analyst because I understand what breaks and why\. 🎓 Graduated MSc in Data Analytics at National College of Ireland \(2025–2026\)\. 🔧 Core stack: Power BI · DAX · Power Query · SQL · Python · Microsoft Fabric · Azure · STIBO STEP / PIM 📍 Based in Dublin — open to hybrid, on\-site, or remote roles in Data Analytics, BI Development, or Application Support\. If you're hiring or know someone who is, let's connect\. I'm actively looking and can start conversations immediately\.
