Title: Expert Excel/VBA Developer — Commercial Product Build (Power Pivot + DAX Required) Post Body I am building a commercial Excel-based product for the project management / PMO market. This product will be sold globally as a standalone tool. I need an expert developer to build it from a detailed specification. This is NOT a one-off dashboard or report. This is a product that will be distributed to hundreds of paying customers. If you have not built Excel products for commercial distribution before, this is not the right project. Skills required: • Power Pivot data modelling with star schema design and DAX measures (CALCULATE, SUMX, FILTER, ALL — not just basic PivotTables) • Advanced VBA for user interface design: navigation systems, UserForms, scenario controls, refresh macros. Not just “copy data” automation. • Professional dashboard design — executive-grade visual quality with conditional formatting, KPI cards, heatmaps • Commercial file protection experience — familiarity with XLS Padlock or similar Excel-to-EXE compilation tools (preferred, not required) Project details: • Budget: fixed price, paid in 4 milestones • Timeline: 12–16 weeks • Detailed specification will be shared with shortlisted candidates after initial screening To apply, you MUST: 1. Show me a screenshot or video of an Excel product you built that was sold or distributed to multiple end users (not a one-off client report) 2. Describe your experience with Power Pivot data modelling and DAX measures specifically 3. Confirm you can work within XLS Padlock constraints (or are willing to learn) 4. Provide your availability for weekly 30-minute check-in calls (UTC/GMT timezone preferred)
