At Cina Datang Corporation, I manage and analyze approximately 15,000 emission records each month. I proposed a tool upgrade and environment setup after the volume caused Excel to overload, and used Python and SQL to improve data processing and detect anomalies, with results shown in a Power BI dashboard.
At Wilmar International, I led a 27-member maintenance team as Assistant Maintenance Supervisor, using SAP PM and spreadsheet dashboards to support daily operations and performance monitoring. Earlier, as a Maintenance Planner, I participated in the early operational phase of a newly commissioned plant and helped standardize and consolidate data into a structured data warehouse using Excel queries.
