Most businesses don't have a data problem. They have a "nobody's making sense of it" problem. That's where I come in. I work across the full data stack. Some clients need a clean Power BI dashboard that their leadership team can actually use on Monday morning. Others need someone to dig into messy datasets, build pipelines, or pull external data through web scraping before any visualization even makes sense. I do both. Here's what that looks like in practice: • Power BI dashboards: KPIs, executive reporting, sales/marketing/ops views • SQL analysis on large datasets: finding patterns, answering business questions • ETL/ELT pipelines: BigQuery, Snowflake, Python • Data modeling, DAX, Power Query: built for performance, not just looks • Data cleaning and transformation: turning chaos into something usable • Excel and Google Sheets migrations into scalable Power BI systems • Web scraping: when the data you need doesn't live in your database yet • Data warehousing: structuring everything so reporting doesn't break at scale I'm currently in two active data roles where I build dashboards and pipelines that people rely on for real decisions. I've also trained analysts in Power BI and DAX. Teaching forces you to understand things at a level that just "using the tool" doesn't. My portfolio has real projects with documented processes, not tutorial screenshots. Take a look and you'll see how I think through problems. Got a data challenge? Message me with a quick summary. I'll tell you how I'd tackle it, no fluff.
