Hi, I’m Andrea 👋

Senior Frontend Engineer with 12 years of experience, the last 9 in senior and lead roles. I build and re-architect high-performance web and mobile products, and I specialise in frontend architecture, performance and modernising legacy systems.

Agentic coding tools are part of how I work now. I use Claude Code daily, with a clear split between what I delegate to an agent and what stays a human decision.

I've delivered work for FIFA, UEFA, the Olympics, NHK, Deutsche Telekom and Moneyfarm, and currently work with international clients across fintech, Web3 and SaaS.

How I work with AI

Claude Code is part of my daily delivery, not a demo. What matters is the division of labour.

I delegate: Scaffolding, mechanical refactors and codemods, test generation, migration groundwork, documentation.
I keep: Architecture and data-flow decisions, API and type contracts, performance and accessibility tradeoffs, security-sensitive paths, and final review. Nothing reaches production without a human diff review.
How I get there: Repo-level context files, tightly scoped tasks, and tests-first prompting, so agent output is verifiable instead of just plausible.
