About
Who I am
I'm a Full Stack & Systems Engineer based in Rio Grande do Sul, Brazil. I work on enterprise applications, legacy system migrations, cloud infrastructure, and industrial automation deployments.
My work spans South America, Europe, Asia, and Africa. I help teams resolve production issues and build systems that support thousands of daily operations.
I also work with technical teams and business leaders to plan projects and present roadmaps to C-suite and VP-level stakeholders.

A traditional welcome
Welcomed with a lamp-lighting ceremony when I arrived at the office in India. This was the start of the on-site phase of a global legacy migration program.

Aligning a global migration
Working sessions with a cross-functional team of nine international developers to align the UWP to .NET MAUI migration blueprint. That same strategy was later presented directly to the Global VP of IT.

Firefighting in production
Dispatched to resolve a critical replication bottleneck: data ingestion was scaled from 20k to over 100k records, cutting replication time in half for the regional operation.

Automation on the factory floor
Architecting a tobacco-purchasing automation system driven by PLC bale queues, industrial scales, scanners, and printers. It was rolled out across five Argentine states with 50+ operators per region and integrated with ARCA-AFIP through a high-security SOAP layer.
