I turn messy, unstructured information — PDFs, documents, free text — into structured data, insight, and automated workflows. From Python pipelines and text analytics to Power BI dashboards that people actually use.
01About
I'm a data professional focused on the unglamorous-but-critical middle of the data world: getting information out of the formats it's trapped in and into shapes where it can answer questions.
That means building Python pipelines that transform PDFs and raw text into structured, quantifiable datasets; applying text analytics with scikit-learn and LLMs to classify and extract meaning at scale; and closing the loop with Power BI dashboards and Power Automate flows so the results reach the people who need them — automatically.
I care about solutions that keep working after I walk away: reproducible, documented, and simple enough for the next person to maintain.
