About Walter Alberto

Senior IT professional with over 30 years of experience helping organizations streamline, integrate, and improve their processes, combining business vision with technological solutions that have a real impact on operations.

I have extensive experience in functional process management, legacy system modernization, software development, and improvement and transformation initiatives in complex environments.

I possess strong functional expertise in HR and payroll processes, with a deep understanding of the legal-operational framework, and I am currently training and specializing in SAP HCM / SuccessFactors platforms, HR-Payroll integration, and associated implementation models.

I act as a liaison between business and technology, translating real needs into clear requirements, simple solutions, and decisions aligned with company objectives, with a practical, results-oriented approach.

In parallel, I develop consultative-operational consulting services for SMEs, supporting owners and teams in business organization, process improvement, operational control, and decision-making, without theoretical consulting or unnecessary technological dependence.
