About

Professional summary

I am a Project Manager and Business Analyst specializing in HR technology implementations, with nearly 10 years of experience in multinational environments. I hold a postgraduate degree in Project Management and a bachelor's degree in Human Resources Management.

I lead end-to-end HR and payroll technology implementations, from requirements gathering, process mapping, and functional specification definition through cutover, validation, testing, and post-go-live support. My experience includes large-scale Workday implementations and Oracle-to-Workday migrations.

I work effectively across HR, IT, development, quality assurance, payroll, benefits, and outsourced service teams. I am experienced in coordinating multi-vendor stakeholders, including Accenture HR Services, and aligning solution design with business requirements.

My strengths include project planning, stakeholder management, organizational change management, risk mitigation, UAT, and cross-functional leadership. I translate complex business needs into practical processes and deliverable technology solutions.

I also bring hands-on HR data, reporting, and analytics experience using tools such as Power BI, PeopleSoft, ServiceNow, Workday EIB, and Workday Studio. I have supported HR operations and payroll processes across Latin America and the United States.

I am focused on delivering stable, scalable HR solutions that improve process efficiency, data quality, user adoption, and operational readiness.
