At Baimskaya, I transformed maintenance planning and execution, shifting the planning horizon from week +1 to week +4 and delivering an average of 97% weekly schedule compliance. I also developed maintenance strategies for critical mining assets, increasing maintenance plans from 3 to 89 per asset.

At Rio Tinto, I developed zero-based maintenance plans and long-range forecasts for the Robe Valley operation, and delivered SAP planning masterclasses to site planning teams. Earlier, I worked in asset planning and maintenance roles at Roy Hill and BHP, supporting lifecycle planning, reliability, shutdown readiness, and maintenance execution.
