Available for new projects. Based in Florence, working worldwide.

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 and 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

Selected work

Different disciplines. One product perspective.

Area

Stage

Work

01

Digital products & operations

Platforms, customer journeys and tools for everyday work.

02

AI, agents & data

Algorithmic systems, multi-agent orchestration and decision support.

03

Immersive & spatial experiences

Digital archives, augmented reality and new ways to explore.

04

Inventions & IP research

Physical product concepts, technical research and potentially protectable intellectual property.

How I work

Four steps, no handoffs.

  1. 01

    Discovery

    I learn how the work actually gets done: the profession, the week and 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.

A founder’s perspective

Jonathan Pierini

I build with the experience of someone who has had to make it work.

As a startup founder, I know how easily bringing a product to market can become slow, complicated and expensive, and still drift away from what the business actually needs. My entrepreneurial and commercial experience shapes the way I build: start with the real problem, test early and keep the essentials in focus.

Speed matters when it helps you learn. I turn ideas into working platforms, test scalability early and keep the brand, the interface and the user journey simple. My experience as a shoe designer at Steve Madden and a client advisor at Prada adds attention to design quality and the way people experience a product.

For the people running the product, simplicity also means continuity: a solid foundation, straightforward day-to-day operations and room to extend the platform without rebuilding everything. AI helps us move faster; human judgement keeps the direction, quality and control in our hands.

Project collaborations, ongoing consulting and medium- to long-term engagements, remotely and worldwide. I can contribute to product direction, a focused code or integration project, a multi-agent system or an end-to-end platform. I measure the work against usable outcomes, less repetition, testable assumptions and room to scale.

Research that can become intellectual property.

I help turn original ideas into technical concepts, prototypes and potentially protectable product elements. My contribution spans research, development and technical documentation for assessment with qualified IP professionals. Patentability, filing strategy and legal protection require specialist review; they are not guaranteed by a prototype.
