How I work with AI

I use Codex, Claude and Cursor every day to explore solutions and develop software. I compare their proposals with the requirements, review the code and verify the result in the product.

CodexClaudeCursor

I get things done.

  1. Understand

    I listen to the people who will use the product, map the process and clarify goals, constraints and priorities.

  2. Build

    I choose a first journey to implement and turn it into something to try. We review the result before extending it.

  3. Test

    I review code, content and interactions, checking the original need as well as errors and unexpected situations.

  4. Deliver

    I prepare a clear handover, agree the release and verify the product in the environment where it will be used.

From one project to the next

What I learn on one project comes with me to the next. RADA brought together sensors, radio links and reliable measurements. CosmoGato meant working through the costs, limits and safeguards of an AI product. With Club Perfumes, I shaped the offer alongside the professional behind it. Each new project benefits from that experience. What I have learned, the mistakes to avoid and a closer understanding of the people who will use it.

My background.

I like getting to know a place through the people who live there. School exchanges took me to Finland and the Netherlands. At university I chose a year in Spain. I studied, debated and built projects with people whose experiences differed from mine. Today I work in Milan and keep looking for opportunities to learn from other ways of living and working.

Start with the problem.

Tell me about the process you want to improve or the product you want to build. We start with its users, the systems already in place and the constraints.

Software and integrations

Applications, APIs and connections between systems. I start with the workflows and the data that need to move between tools.

Inside the project

Web products and online presence

Websites and web apps that make an offer clear and help people use it. Content, interface, accessibility, SEO, GEO and AEO are part of the same work.

Inside the project

Automation and AI

I identify repetitive steps and assess where automation is useful. Integrations and AI, with checks, error handling and clear responsibility.

Inside the project

Collaborations

My community across software, AI and design. Professionals and businesses I collaborate and exchange ideas with.

An interesting problem?

Tell me what you want to build or improve, who will use it and what constraints you have. I’ll get back to you so we can work out where to start.
