Software and AI that give you your time back.

I design and build the tools professionals actually work in — AI agents, automated workflows and algorithmic systems, turned into products so simple your team uses them from day one.

Saving time and simplicity are the basis of every project I take on. One person from idea to shipped product: strategy, design, code, deployment.

AI tools & agents
LLM-powered features, custom agents that automate the repetitive work
Algorithmic systems
Scoring, matching and decision engines built around your data
Automation
Workflows that remove manual steps instead of digitizing them
Product craft
Interfaces so clear the training session is five minutes

What I do

Four ways I get hired, all of them ending in something that runs.

01

Product & platform development

Full SaaS and web applications, from the data model to a deployed product people use every day. I take the whole thing — architecture, interface, build, release.

Typical timeline
6–16 weeks to first production release
What you get
Deployed application, data model and documentation, admin access, handover session

02

Rapid prototyping & mockups

Concept to a clickable, testable interface in days. Decisions get made on something real instead of on a slide, and you can put it in front of users before committing a budget.

Typical timeline
3–10 days
What you get
Interactive prototype, key user flows, notes on what to validate next

03

Technical solutions & integrations

AI features, data pipelines, automations, and connecting the tools that refuse to talk to each other. Usually the difference between a process that runs itself and one that eats a person's week.

Typical timeline
2–6 weeks
What you get
Working integration or pipeline, monitoring, runbook for your team

04

Fractional CTO / technical partner

For founders who need technical judgement before they need a team. Architecture decisions, build-or-buy calls, hiring input, and someone who can also write the code when it matters.

Typical timeline
Ongoing, monthly
What you get
Weekly working sessions, technical roadmap, decision records, hands-on build time

How I work

Four steps, no handoffs.

  1. 01

    Discovery

    I learn how the work actually gets done — the profession, the week, the spreadsheet everyone secretly relies on.

  2. 02

    Prototype

    A clickable version of the product within days, so we argue about something real rather than about a description.

  3. 03

    Build

    Data model, interface and logic built together by one person, in short visible increments you can use as they land.

  4. 04

    Ship & iterate

    Deployed to production, watched under real usage, then sharpened where the real usage says it should be.

One person is faster than an agency because nothing has to be translated. There is no brief passed from strategy to design, no design passed to a developer who reinterprets it, no meeting to reconcile the two. The person who decides how it should work is the person writing the code, so a decision on Monday is in production on Wednesday — and when it turns out to be the wrong decision, it changes just as fast.

Background

I came to software from fashion design, and it shows in the work.

Founder of an Italian registered innovative startup, former fashion designer at Prada, and a working artist. That path isn't a detour from product development — it's the reason my products feel considered.

Fashion is a discipline of proportion, material and finish, made under real deadlines for people who will judge the result in a second. It trains you to treat the surface of a thing as part of its function, and to keep refining after it already technically works. Most professional software is abandoned exactly at that point.

So the tools I build for analysts, nutritionists and operators are held to the same standard as an object: clear hierarchy, no decorative noise, and a level of finish that makes people trust the thing they're putting their work into.
