I have worked for more than 30 years in operations, Supply Chain, after-sales, customer service, cost management and operational transformation.

My experience was built within large-scale operations, leading teams and processes and delivering results in Brazil, Europe and South Korea.

Over 14 years at Samsung Electronics, I progressed from managing the contact center to leading Service Operations in Brazil — including a period at the company's global headquarters in South Korea, where I supported the operations of 16 European subsidiaries.

Throughout my career, I have led large-scale operations, including a national network handling around 500,000 repairs per year, as well as cost reduction, Supply Chain, logistics, procurement and operational transformation programs.

Today, I apply this experience to consulting projects for companies that need to improve their operations, reduce costs and turn processes into results.

I am a senior Human Resources professional and HR Business Partner, with more than 25 years connecting people strategy to business goals.

As an HR Business Partner, I worked at SKY — in its corporate units in Brazil, interfacing with Latin America and serving 12 vice presidents — and at Comgás, working with five divisions and supporting leadership decisions on hiring, promotion, development, succession, compensation and department restructuring.

Before that, I was an HR manager at Ipsos, working on corporate projects for Brazil and Latin America; at Tivit, handling recruiting, selection and training for about 8,500 people across five sites; and at Gennari & Peartree. I was part of Atento's launch in Brazil, setting up the recruiting and selection function for the opening of its contact center operations.

As a partner at Celli Consultoria, I lead training programs, leadership guidance, talent management, recruiting for managerial and operational roles, and organizational change management.
