The Journey
From engineering data pipelines at one of Latin America's largest banks to building AI-powered solutions in Sydney — I'm driven by the challenge of transforming complex data into actionable intelligence.
Master's in Data Science at the University of Queensland, currently interning at One51 building RAG frameworks and data migration tools.
"I've migrated millions of banking records from IBM Mainframes to the cloud, bridging legacy and modern systems while maintaining strict compliance."
