What I'm looking for

I'm looking to transition into a data analytics role where I can use SQL, Excel, and Power BI to clean data, uncover patterns, build clear dashboards, and support evidence-based decisions.

I'm building a data analytics portfolio with SQL, Excel, and Power BI, including a normalized six-table PostgreSQL database that evaluates AI-generated text quality across GPT-4, Claude, and Llama. I've also cleaned and analyzed roughly 9,800 Superstore records to identify customer, product, monthly, and yearly sales trends.

Over six years of remote language evaluation and education work, I've developed rigorous criteria-based analysis, quality control, and pattern-identification skills. As a freelance Language Specialist and English Teacher at Galway Academy, I've evaluated AI outputs, analyzed student performance, and clearly reported findings to support evidence-based decisions.
