What I'm looking for

I seek roles where I can apply engineering and data skills to improve operations, contribute to quality compliance, and work in collaborative, growth-oriented teams.

I am an Industrial Chemical Engineer with hands-on experience in contract administration, quality control, and data automation, focused on improving operational efficiency and compliance.

At Petróleos Mexicanos I managed physical and virtual files, supported maintenance contract administration for additivation systems, and implemented statistical quality control across storage terminals and refineries.

As a freelancer I have worked as an Internet Content Analyst for Latin America and as a Business Analyst Assistant/Interpreter, consolidating financial reports, handling BI tools, and localizing materials in Spanish and Portuguese.

I bring a practical, collaborative approach, continuous improvement mindset, and multilingual communication skills to help teams make data-driven decisions and optimize processes.
