Port-Leucate / Grenoble

I build systems. And I make them understood.

Six years of online communities, a BTS in Communication finished top of the class, an electrical engineering and industrial computing degree in progress, and Helix Health, a health app I design and build alone.

Founding project

Helix Health, the app that connects what others keep apart

Sleep, movement, supplements, nutrition and biomarkers in a single explainable score, with no AI model, on a home-built database. Data on the device, European hosting, free and ad-free. I design and build the project alone, from the product to the mobile app, with a sourced biohacker blog whose method and corrections are public.

Communication case studies

Six assignments, from the BTS to internships

Each case study details the context, the strategy and what was produced. No logo wall, work that is shown.

Communities

Three accounts, three audiences, one method

One account of my own for six years, one managed for a client, one run until 2024. That is where I learned what an algorithm rewards, and what a community remembers.

Method

Understand the system before making it speak

In a company, communicators look like hot-air merchants to the technicians, and technicians look narrow-minded to the communicators. Everyone decides without understanding the other side, and it costs money, time and competitive advantage. So I started holding both ends.

My bookshelf runs from Robert Greene to Frank Herbert, my downtime from grand strategy games to 3D printing and model rockets. The more different the subjects, the more you see the links between them.

  1. Understand

    The starting point is always the why: audience psychology and market analysis before any creative work.

  2. Create and deploy

    A strategy is nothing without its execution: from positioning to website, from distribution plan to video.

  3. Measure

    A campaign’s metrics read like a blood test: what moved, what did not, and why.

Personal project

Trinity 1, a rocket that really lifts off

Modelled in Fusion 360, 3D printed, hand-wired and launched at Leucate. The first version was too narrow to release its parachutes; the second generation widens the tube and keeps the rest, down to the ESP32 launch controller I soldered myself.

  • 31 cmtall
  • C6-3Klima motor

    BTS Communication, top of the class

    Six real case studies, from an association to a festival, and the programme itself as a project: video, identity and website. See the project
