01 / PROFILE

A practical approach
to complex technology.

I’m an IT manager and mechanical engineering graduate based in Monaco, with a background spanning technology, product innovation, and entrepreneurship.

My experience includes managing IT across a private family office’s restaurants, offices, and warehouses; coordinating Kinder innovation projects at Ferrero; and launching businesses in engineering consulting, technology support, and e-commerce.

I hold master’s and bachelor’s degrees in mechanical engineering from the University of Southampton, both with First Class Honours. I combine analytical thinking with hands-on delivery and coordination across technical and business teams.

I use AI coding assistants to turn practical ideas into working applications, defining requirements and refining features through hands-on testing. My personal projects span portfolio tracking, tennis scoring, and smart-home controls.
