Ideas are cheap.Evidence is the work.

Four systems for navigating uncertainty.

Different domains, one consistent standard: assumptions should be explicit, evidence should stay attached, and outcomes should be testable.

01
Quantitative research system

Cube

Can a market result explain exactly why it should be trusted?

An evidence chain for research, backtesting, execution, and monitoring. Every conclusion stays connected to the data and assumptions that produced it.

02
European power markets

Energy

What changes when price has to answer to physics?

Decision systems for power markets, where timing, physical delivery, regulation, and uncertainty have to coexist in one operating model.

Data you can trust

Wayfinder

What did we know, when did we know it, and was it healthy?

Infrastructure for finding data, tracing its origin, understanding its freshness, and deciding whether it is reliable enough to use.

Auditable forecasting

Forecast Lab

Can a belief become more useful by admitting it may be wrong?

A workbench for resolvable questions, explicit probabilities, causal assumptions, and revisions that preserve what changed and why.

Working across

Markets, energy, data infrastructure, forecasting, and AI-native workflows.

Operating method

Find the weak assumption. Build the smallest useful proof. Keep the evidence attached.

Research direction

Turning ambitious ideas into measurable systems that can be evaluated and improved.

Curious by default.

I’m a self-taught software builder from Italy. I’m most at home turning ambiguous questions into working products—learning the domain, building the system, and testing whether the idea holds up in practice.
