About

Professional summary

I am an economist and Customer Experience leader with more than 15 years of experience leading customer service, commercial development, retention, and cultural transformation initiatives.

I design and implement customer experience models that connect NPS, CSAT, PQRS, customer journeys, and service quality metrics with measurable business outcomes, including retention, operational efficiency, and revenue protection.

I have led large-scale service model deployments, organizational change programs, and training initiatives for hundreds of employees across multiple locations. My approach combines service design, process optimization, and change management.

I have achieved sustained improvements in PQRS performance, complaint quality, response times, customer satisfaction, and Net Promoter Score. I also bring experience managing strategic corporate accounts and integrating commercial and customer experience processes.

My background includes work in education, manufacturing, packaging, sales, consulting, and corporate services. I am available immediately and focused on senior customer experience, service transformation, and change management opportunities.
