ABOUT ME
Located: Western NY
I build reliable systems that turn messy, real world numbers into clear, actionable stories. In my own home, that looks like color coded bill audits, subscription breakdowns, and tracking every dollar so I can see patterns, plug leaks, and make calm informed decisions.Professionally, I bring that same mindset to organizing data, cleaning it, and structuring it so it's easy to analyze, explain, and act on.I care a lot about integrity and stewardship, so i document how i get from raw data to final insight, double checking my work, and making sure anyone looking at my work can easily follow the trail, I dont build reports for report's sake. I want the numbers to change how people plan, spend, and improve.Previously, I've worked in customer facing retail, manufacturing, and preschool teaching roles, which taught me how real people and real businesses operate and why clear, reliable data and simple systems matter so much in everyday life. Outside of work, I'm in Bible study, parenting mode, and serving in the sunday's Children's ministry. Where I teach generosity, self-love, and joy through simple,theological, and practical lessons that stick.

project 1
PROBLEM:
I wanted a clear baseline picture of client personal finances before they started using my bill binder system, so I could see exactly where the money was going in a “wild” month and have something to compare future progress against.WHAT I BUILT:
I built a one-page Power BI dashboard that shows: Spending by Category (pie chart), Income and Spending (bar chart), Income and Spending by Day (area chart), and Spending by Month split into Fixed vs Flexible ( stacked bar). The layout and formatting are designed to make the story of the month easy to read at a glanceTOOLS USED:
Power BI Desktop
Google Sheets/CSV bank export
Basic data cleaning and grouping in Power BIWHAT I LEARNED:
I learned how to import and model real bank data in Power BI, create multiple visuals that tell one consistent story, and use formatting (colors, labels,fixed vs flexible categories) to make financial patterns obvious. This project also gave me a ‘Baseline on account status’ i can use later to show behavior change over time.
