about

Senior frontend engineer with documented professional experience since October 2012, specialised in large-scale single-page applications across iGaming, banking, fintech and AI products.

Track record leading frontend teams since 2018. Currently focused on streaming platforms, LLM-agent tooling and semantic memory systems.

I treat personal projects as a sandbox for what's emerging — new models, frameworks and runtimes. What survives the stress-test there earns its way into the production work I ship to clients.

Husband, father of two daughters, traveller. Curious by default and methodical by discipline — I research deeply, structure what I learn, and keep things organised.

Based in Italy. Available for senior, lead and architectural roles.

A navigable view of my career — each company linked to the technologies, domains and LLM tools used during that period. Rendered from the same semantic memory system (MemPalace) I use to give my AI agents long-term context. Hover any node to focus its neighbourhood.
