I’m a Data Analyst with 2+ years of experience building analytics functions from the ground up and turning raw data into insight leadership can act on. I’m comfortable across the full stack—Power BI, SQL, and Python—and I focus on KPI design, self-service dashboards, and HR/Operations analytics.

As a founding team member, I set up data infrastructure, governance, and reporting standards from zero. I built 8 executive Power BI dashboards tracking revenue, 370+ orders, and operational KPIs, cutting reporting turnaround from 2 days to under 12 hours.

I also automate reporting workflows by building ETL pipelines in Python and SQL. That reduced data prep time by roughly 70% and improved the accuracy of executive-facing reports, while AI-assisted workflows shortened the time from raw data to leadership insight.

Previously, I was the first analytics hire on a contract, where I stood up the analytics function and delivered weekly executive insights. I built Power BI and Excel dashboards, improved data accuracy by around 40% with ETL pipelines, and set a standardized reporting framework and KPI dashboards that are still in use.
