Build with data.
Be a force for positive change.

Matteo’s Lab is where I use data, research and technology to build tools and stories that help people, communities and businesses understand problems, discover opportunities and make better decisions.

THE GUIDING PRINCIPLE

Be a Positive Force.

I want the work created here to move beyond the screen: helping people understand something important, improving how a business serves its customers or giving a community a stronger voice.

A principle from my alma mater

WHY THIS LAB EXISTS

Technology should make life more understandable and more useful.

We have access to more information than ever before. The challenge is turning that information into work that helps someone: a clearer decision, a better service, a useful tool or a story that deserves greater attention.

01 • UNDERSTAND

Research real questions

Explore datasets, listen to communities and investigate the underlying causes behind problems rather than jumping directly to a polished answer.

02 • BUILD

Create useful tools

Develop visualizations, browser extensions, applications and analytical systems that make complex work clearer and easier for people to use.

03 • SHARE

Document the journey

Publish the questions, code, experiments, mistakes and decisions behind each project so the work can be understood, challenged and improved.

CURRENT PROJECT

Learning from the Pacific through open data.

My first data competition is also the first complete expedition documented inside this lab, from understanding the available evidence to building the final visual story.

PROJECT 001 • JULY 2026

Pacific Dataviz Challenge 2026

I am exploring how open data can reveal meaningful stories about climate, communities and public policy across the Pacific.

The complete process will live here: research notes, hypotheses, data cleaning, code, visual experiments, failures, findings and the final submission.

THE BIGGER PURPOSE

More insights.
Shared benefits.
Better outcomes.

I have been fortunate to travel to remote places and meet communities whose lives are closely connected to farming, fishing and natural resources.

Seeing pollution, waste and extreme temperatures affect these places changed how I think about technology. Data is not only something to analyse. It can help us understand what is changing, make problems visible and support people who already hold deep knowledge of their environment.

The same principle applies to businesses and digital products. Better measurement and better tools can remove friction, improve services and help organisations treat their customers more fairly.

This lab is where I connect those worlds: data, technology, business, communities and the responsibility to contribute something useful.

HOW I WANT TO WORK

Four principles behind every project.

Start with curiosity

Ask better questions before choosing the technology or the answer.

Stay close to reality

Understand the people, communities and systems represented by the data.

Build transparently

Share the process, limitations and reasoning behind the final work.

Leave something useful

Create work that improves understanding, decisions or everyday life.
