Legal analysis in writing on artificial intelligence, data, litigation and cross-border matters, signed by the lawyer who handles those cases.

Approach
Every article cites the rules and the judgments that apply, so that you can check what we say before you take our word for it.
They are written by the lawyer who handles that field at the firm and carry their name and date, so you know who is speaking and how current it is.
We prepare the texts with the help of artificial intelligence, and the lawyer who publishes them reviews and signs them. We explain how we use it.

I see legal practice as a discipline of precision. I work where the law meets technology and cross-border operations, and I read code and contracts with the same attention. Before accepting an engagement I tell you whether it is worth pursuing and what it costs, at a fixed price.

I work where economic law meets technology: litigation, contracts and artificial intelligence systems. I am drawn to the ground where the rules are still being written, and I have brought that same rigour to litigation since my first year in practice.
