Antonio Zuccon Ghiotto, front-end developer in Padua, Italy

I build interfaces, then prove they work.

I build with React, Next.js and TypeScript for e-commerce, telco, finance and publishing. I come from CRO, so before I write code I decide how we'll measure the result.

What I do

Front-end development
React and Next.js apps and storefronts, reusable components, performance and accessibility on high-traffic sites.
CRO & A/B testing
Hypothesis, variants built in Adobe Target, Optimizely or Dynamic Yield, and a clear read of the results. From idea to decision.
Tracking & analytics
Measurement plans with Tealium iQ and GA4, reliable events on every variant, data you can trust.
AI features
Language models inside real products: chats that act on the interface, RAG, pipelines with open-source models.

Side projects

I play live, and most of my side projects start there.

REAPER Copilot

In development

AI assistant for music production

A chat panel docked beside REAPER that reads and edits the project. Ask it to "mix like this Queen track" and it works on tracks, effects and the master from a reference. A fast model handles simple commands and a stronger one handles mixing, with stem separation feeding real data to the model. Designed as a low-cost subscription.

  • TypeScript
  • Claude API
  • DeepSeek
  • Stem separation
