Most spreadsheet systems fail because they are built for data, not for people. I build clean, structured Google Sheets systems that are easy to use, visually organized, and built to support coaches, teams and real business workflows. My focus is turning messy spreadsheets into clear, scalable systems that teams can actually work with. I specialize in spreadsheet UI/UX design and dashboard systems for real estate, operations, finance, sales tracking, and reporting. What I help with: • Spreadsheet UI/UX Design • KPI & Business Dashboards • Operations & Tracking Systems • Financial & Sales Reporting Sheets ▪︎ Data Entry for Large Datasets • Spreadsheet Redesign & Optimization • Google Apps Script automation (inside Sheets) Clients usually hire me when their spreadsheets are: • hard to navigate • visually cluttered • not structured for decision-making • or need to be turned into a usable system I don’t just build formulas. I design spreadsheet systems that are clear, structured, and easy to use.
