Marco Dong

AI Product Engineer. Agent products, end to end.

Engineer with four years delivering software to other people’s businesses, from Salesforce consulting at Deloitte to B2B platform work for Italian energy majors. I currently ship a production LLM agent inside a regulated wealth manager, including the evaluation work that decides whether it is safe to release. Alongside that I have run seven freelance engagements end to end, from first conversation to invoice, and hold an MBA. Native Italian, based in Milan.
