I improve polyolefin quality, product development, and production performance across manufacturing operations.

Portugal
Message

At Repsol Química in Sines, I provide technical support on plant quality issues for LDPE, EBA, and PP while coordinating product-development projects that improve quality and reduce costs.

I approve new materials, define specifications, support customer-specific developments, and help resolve customer complaints. I also coordinate cross-functional digital projects for product quality control and operational production management.

Across Repsol roles in Portugal and Spain, I've optimized PP production, monitored raw materials and finished goods, managed non-conforming products, and coordinated corrective actions. My work includes maintaining compliance with ISO 9001:2015, FSSC 22000, IATF 16949, and ISCC.

My background spans process engineering, production leadership, automation, and industrial process control, including work with steam cracking, 1,3-butadiene, HDPE, DCS implementation, and advanced control solutions.
