As a freelance data analyst, I built a Power BI dashboard for a six-store grocery chain’s CEO weekly operations meeting, covering sales, margin, shrink, promotions, and store trends. I automated export cleanup, designed a weekly calendar model with 22 DAX measures, and shared four recommendations based on my findings.
For a wholesale food distributor, I created an Excel report from 19,341 sales records that showed Q1 accounted for 37–43% of annual sales. I also work as a PTO Engineer at Sinopec, maintaining production data, project databases, and technical documentation.
