  • Written report related to a potential raw material pre-grinding project to be developed inside the company, describing its benefits and investments.
Skills

Teamwork

  • As a team member I am prone to ensure trustworthy relationships and focus on the team objective rather than individual recognition.
  • As a project leader I like to stablish and consolidate work teams in which the performance is based on boost the strengths of each member and support the weaknesses by effective communication.
  • Inside the cement production area I have been able to build strategies focus to improve overall teams performance by making strong relations with maintenance, quality and administrative areas.

Leadership

  • Manage team of engineers in deadlines situations keeping personal life equilibrium as a priority.
  • As a production’s engineer I was in charge of a 15 people team which a lead, support and join in order to reach our internal objectives. In terms of production we reached the higher monthly cement production’s rates in all the plant’s history at that point.

Process optimization

  • Solid knowledge in key cement process variables and methods to carry process audits and develop business cases and improvements based on the information analysis.
  • I was in charge to develop a program to increase cement mills performance in which two main goals were met: Reducing energy and chemical additives consumption and the replacement of clinker for a less cost raw material. With these actions a cost reduction of almost $3/ton (10%) of cement was reached.
