At Telefônica Vivo, I structured Application Portfolio Management data and evolved the application metamodel in LeanIX. I also supported data integration between ServiceNow and LeanIX and the move from manual application-obsolescence controls to structured information.
Across enterprise architecture work at SysMap and Atos, I contributed to architecture practices, TOGAF-based principles, and views connecting business capabilities, applications, and integrations. At SysMap, I also conducted Event Storming workshops to understand processes, systems, and business interactions.
Earlier, at Accenture do Brasil, I participated in evolving Petrobras’s legacy MCC system from ASP to .NET/C#, with a layered architecture and centralized MS-SQL Server database. My work spans enterprise and solution architecture, systems integration, automation with n8n, and applied AI.
