I work at the intersection of building reports and teaching them. At MIUUL I run end-to-end analytics for consulting clients in retail, e-commerce, and tourism — consolidating multi-source, time-series data through SQL into Power BI dashboards that business units actually rely on. In parallel, I train data analysts, which keeps my fundamentals sharp and forces me to explain the "why" behind every model.

What I care about: dashboards that survive handover. Clean data models, documented logic, and a data dictionary so a report still makes sense six months after I've moved on.

Before BI, I spent 6+ years in brand-level reporting, performance and sentiment analysis, and content strategy. That reporting instinct — asking what a number is actually for — is where this career started.
