I turn financial data into clear analysis that management can act on: budgets, forecasts, project margins, costs, cash flow and variances. I have done this in plant engineering, chemicals and mobility in Germany, building on an accounting career that began in Taiwan.
What I bring
Project controlling in plant engineering
Budgets, forecasts, cost and revenue monitoring, and customer billing for plant-engineering projects at T.EN Zimmer (Technip Energies group).
Product cost controlling in SAP
Standard price calculation, actual costing with the Material Ledger, CO-PA and cost centre accounting at INEOS Styrolution, including validation of all European products.
Closings under HGB and IFRS
Monthly, quarterly and year-end closings, provisions and group reporting in industry, plus closing support for international clients of an accounting firm.
A bridge between finance and operations
I work closely with project managers, accounting and management, explaining what the numbers mean and what should happen next.
