Hi đź‘‹
I'm an Italian software engineer moving pixels in the world wide web.

I build and lead web platforms at scale. I specialize in frontend architecture and design systems, and work best at the intersection of design vision and technical reality.

A decade across the Arduino ecosystem, frog, lastminute.com, and now Stedi.

Experience

Expand for details

StediCurrent
2026

Building the web product for the world's only API-first healthcare clearinghouse with React, Next.js, and TypeScript.

Stedi is a programmable healthcare clearinghouse: modern APIs for eligibility checks, claims, and ERAs that let healthcare technology companies exchange X12 HIPAA transactions with payers without dealing with EDI or carrier-specific connectivity.

Key initiatives

  • Web product: Building foundational features in Stedi's Next.js and TypeScript application, working from Figma designs alongside design, product, and backend engineering.
  • Design language system: Contributing reusable, responsive, accessible React components to the shared design language.

Lastminute.com
2023 – 2026

Led the Next.js / RSC re-platforming of weg.de and the company-wide Design System — A/B-validated work that lifted CTR 15% and conversion ~4% (peaking at 10%).

lastminute.com is a European leader in the travel domain, operating a diverse ecosystem of sub-brands and web applications across multiple markets.

Key initiatives

  • Led the architectural re-platforming of weg.de to a modern Next.js stack, replacing a legacy React monolith with a RSC-driven architecture.
  • Primary lead for the new company-wide Design System: architected a Multi-brand Token System unifying dozens of white-label applications, and led hiring for dedicated design talent to bridge Figma and production code.
  • Measuring business impact: Partnered with data teams to monitor KPIs, conversion, and A/B tests — building internal dashboards (Grafana, GA, Sentry) to validate migrations and tie technical work to revenue.

BOOM
2022

Built in-browser image-editing features for an automated visual-content platform at an early-stage startup.

BOOM was an Italian startup (Forbes 30 Under 30) building automated visual content management. The product was browser-based image editing; the company didn't survive, but the engineering problems were fun.

Key initiatives

  • In-browser image editing: Built editing tools for manipulating large visual assets directly in the browser — the technical core of the product.
  • Standards & mentorship: Set code-quality practices and mentored junior developers through a fast, high-pressure delivery cycle.

frog
2018 – 2022

Delivered end-to-end frontend architecture and hi-fi prototypes for Fortune 500 clients; built scalable component libraries and token-driven design → dev handoffs.

frog is a global creative consultancy. I was a core member of a lean, cross-European engineering team (Munich/Milan/London) delivering digital products for Fortune 500 clients.

Key initiatives

  • End-to-End Product Delivery: Developed frontend architecture and high-fidelity functional prototypes for market leaders in the Automotive, Retail, and Insurance sectors, transitioning from conceptual design to production-ready code.
  • Technical Modernization & Recovery: Contributed to the technical rescue and revamp of a legacy codebase for a Major Telecommunications Provider, working alongside external consultants to re-architect the platform into a modern React application.
  • Design Systems Advocacy: Partnered with design teams to establish scalable component libraries, educating stakeholders on technical feasibility and token-driven structures to ensure seamless handoffs and developer-ready specifications.
  • Cross-Disciplinary Innovation: Collaborated directly with designers to bridge the gap between physical and digital, utilizing React, Angular, and Arduino to validate complex hardware-software integrations for emerging ventures.

Arduino
2015 – 2018

Core developer of Casa Jasmina, an open-source smart-home “Living Lab” created with Bruce Sterling, and author of docs & libraries used by thousands of makers.

Arduino is a global leader in open-source hardware and software. Here I was the core developer of Casa Jasmina — a collaborative “Living Lab” for open-source smart home technology created with Bruce Sterling.

Key initiatives

  • IoT Interface Development: Engineered web-based interfaces and communication layers for connected home devices, exploring the intersection of open-source hardware and human-centric digital control.
  • Educational Leadership & Open Source: Authored comprehensive technical documentation, libraries, and tutorials that enabled thousands of makers globally to build and scale their own connected objects.
  • Knowledge Design & Workshops: Led technical workshops at universities and corporate environments across Europe, educating diverse audiences on the practical implementation of IoT and smart-home ecosystems.
  • Technical Communication: Balanced engineering with technical writing to bridge the gap between complex hardware protocols and accessible developer experiences (DX), fostering a global community of innovators.
