I had have the luck to work as consulter of planning and cost, for construction projects, for many years. I had been the client's planner and the subcontractor's planner, the two principal views in a project I have a wide experience on the use of Project software: Artemis, MS-Project, Primavera 3/6, SAP-PS, Montecarlo and Pertmaster. A wide experience making courses to training on project control and risk analysis or tricky Excel support. I worked to Vectra (Engineering and control consulters), PDVSA (Venezuelan oil company) by 12 years, as a SAP-PS (Project System) freelanceer by 16 years, and the last 3 years as Schedule&cost control (Pentech Ibérica, construction consulters).
