We are looking for an experienced Power BI developer to build a dashboard for our Quality Control sample tracking process. The process covers feedstock samples, lab sample flow, finished goods samples, and customer release samples. We already have a working Excel file with all tabs, logic, statuses, and workflow connections built and functioning, plus a separate technical specification document. The Excel file should be used as the main source to understand the business logic and reporting structure. What we need: Build a Power BI data model based on the existing Excel structure Create dashboards for sample status, lab progress, overdue items, approvals, and customer release readiness Add filters and drill-downs by supplier, product, sample type, lab, customer, status, and date Include a management dashboard with key KPIs Keep the solution practical, clean, and easy for business users Important: This is not only a dashboard design task. The developer must understand process logic, status flow, and relationships between sample IDs, lab requests, approvals, and dispatch readiness.
