About and skills

My work spans machine learning and generative AI: forecasting, risk and recommendation models on one side, AI agents and multi-agent systems built on retrieval-augmented generation (RAG) on the other. I judge a model by the business impact it delivers.

I have led and contributed to ML initiatives that improved operational efficiency, reduced risk and supported strategic decisions at scale, in banking, telecommunications, automotive and consulting.

I take models from experimentation to production, working closely with engineering and business teams on Google Cloud and AWS. My background includes large-scale data systems, model deployment and analytics for organizations with thousands of users.
