Message

At Alumina S.A, I led foundry, manufacturing, and foil operations across three production lines, with a team of 60. I improved operational efficiency by 12% and raised the service level from 90% to 98% through process standardization and KPI management.

I also implemented cost and raw material optimization strategies, including a raw material initiative that generated savings of COP 550 million per year. I developed a cost simulator to support real-time, data-driven decisions.

Earlier at Alumina S.A, I designed and implemented the SPA Continuous Improvement System based on Lean Manufacturing, and worked on process standardization, methods and time studies, and SAP MM and QM optimization. My work draws on Lean, Kaizen, DMAIC, and PDCA to improve manufacturing operations.
