Argentina

Message

At C&S Informática, I developed and updated banking reports using C#/.NET and SQL, adapting historical data to support audit and regulatory-compliance reporting. I also fixed security vulnerabilities and optimized backend code for reliability.

At COGNIZANT, I designed and maintained production .NET applications for Cargill – Global Operations. I built services and internal tools for integration, monitoring, and automation, and resolved L3 incidents using .NET, SQL Server, and PL/SQL.

Earlier, I developed backend components at SICLABS and built web and desktop applications from scratch at TARGET MINDS CONSULTING & SOFTWARE. My work spans APIs, data access, and integrations across legacy .NET Framework systems and modern .NET applications.
