  Consulting but also seeking project, reliability, maintenance and/or cfd engineer opportunities

  I have started consulting companies using reliability tools to help them solve their issues. Right now I am working on applying the root-cause analysis (RCA) method for helping a company to get rid of some defects during their manufactoring process. Still focused on updating my competencies in order to provide more value to any company requiring my services. Refreshing knowledge in:▪️ Root Cause Analysis (RCA)▪️ FMEA▪️ Reliability Engineering▪️ Maintenance Management Basics▪️ Operations Management Fundamentals▪️ RCM - Optimze Asset management▪️ Scrum: The BasicsI am currently finishing some other courses in Project Management and Maintenance Planning to refresh my knowledge. I am also starting to get prepared for the PMP and CMRP certifications. Show less
