Data, Analytics, ML & Software Engineer
With 9+ years of experience, I specialise in architecting and delivering end-to-end cloud data platforms and AI systems that create real business impact — from ingestion to insight.
Currently at DNX Solutions in Sydney, I delivered a forecasting tool that improved order prediction accuracy by 80%, and led a 5 TB Azure-to-AWS data migration. I also co-founded Nuniversity, a non-profit education platform focused on sciences, engineering and technology for underserved communities.
I hold two MBAs from USP/ESALQ — Business Administration and Data Science, AI & Analytics — giving me the rare ability to translate complex technical solutions into business value. My work spans fintech, e-commerce, retail, and consulting across Brazil, the UK, Portugal, and Australia.
