I turn ambiguous growth problems into working systems.

I work across growth, product and technology to identify what matters, build the first version and turn it into something measurable, repeatable and useful.

From strategy to shipped product, I stay close to both the business problem and the actual build.

01What I do

What I actually do

01

Find the problem behind the request

The initial brief is rarely the real problem. I dig into the business, the users and the existing process before deciding what is worth building.

02

Turn strategy into something real

I prototype and ship websites, funnels, tools, workflows and product experiences. A recommendation is where I start, not where I stop.

03

Build systems, not isolated campaigns

I connect acquisition, content, conversion, automation and data into repeatable loops that can be measured, improved and eventually scaled.

04

Lead across functions

I bring marketers, developers, designers, product people and operators around one shared outcome, even when no single team owns the whole problem.

04This & that

This & that

Paris, London, Barcelona, Miami, San Francisco, and now near Toulouse. I have worked remotely for the past six years. Father of two, which is its own kind of operations role. CrossFit and Hyrox two or three times a week, skiing when the season allows, and padel occasionally.

I am the sort of person who starts a quick prototype and keeps going until it actually works. I find it difficult to market something without first understanding how the business and the product really work underneath.
