Dai Loi Dang

Recent B.Sc. Data Science graduate (UEH) already owning BI end to end in a supply chain setting. I built the real-time Power BI dashboard that became the single source of truth for production, inventory and outbound shipments — replacing manual Excel reporting.

Day to day I monitor KPIs, investigate unusual movements through plan-vs-actual variance and root-cause checks with the teams involved, and improved data quality until report discrepancy fell to 1%. Strong in SQL and Excel Pivot Tables, with Python for larger datasets.

• Dashboards & KPI reporting: built and maintain a real-time Power BI dashboard (DAX, Power Query) covering production, inventory and outbound shipments — the plant's single source of truth, replacing manual Excel reporting for leadership and operations.
• Business performance monitoring: track daily and weekly KPIs, flag unusual movements, and run plan-vs-actual variance and root-cause checks with the teams involved so deviations surface early rather than at month end.
• Stakeholder collaboration: gather reporting requirements directly from Purchasing, Warehouse and production, translate them into dashboards and tables, deliver ad-hoc extracts, and train non-technical users to self-serve.
• Process improvement & data quality: standardised data-entry and reconciliation rules across departments, cutting report discrepancy to 1%; automated recurring reports with Apps Script, saving 40–50% of processing time (~7 hrs/week per department).
• ETL & data preparation: consolidate multi-source operational data (Google Sheets, internal systems) into analysis-ready tables using Power Query, Apps Script and the Sheets API.
