On paper I do marketing and communication — BUT MMI, currently at ADN Technologies and president of Sapense SAS. In practice I spend my evenings on a reverse-engineered BLE protocol and a CMS with no database. I have found that the two jobs are the same one: figure out what a thing is really for, cut everything that is only there out of habit, and say plainly what is left. It just happens in a different file format.

Each one removes the piece everyone treats as non-negotiable, then asks what is actually left to build.

G1 Extended — an open-source Android client for Even Realities G1 smart glasses, written against a reverse-engineered BLE protocol: two Nordic UART radios, one per temple. HUD layouts the official app never exposes, hardware events it throws away, and a path for your own microcontroller to push lines to the lens. No account, no telemetry, nothing leaves the phone.

CMS — a PHP CMS for the sites nobody writes software for: town halls, associations, schools, small practices. Pages, accounts and config are files, so there is no database to install and no root access to ask for. The core merges every plugin's CSS and JS into one file each, in an order the plugins declare themselves — fifteen plugins still cost two blocking requests instead of thirty.

VectorFix (private · pre-alpha) — absolute visual localisation for UAVs in GNSS-denied conditions, matching a nadir camera against vector map data rather than imagery. France in 1–3 GB instead of 5–10 TB, cold start with no position prior, targeting an ESP32-S3 at roughly half a watt. The core hypothesis is not validated yet, and the README says so.

Start Browser (private) — one browser on two engines: an Android fork of FOSS Browser and a desktop build of Gecko from Firefox ESR source. Neither repository carries engine code — the desktop one is a mozconfig, a branding folder and one stylesheet, and fetches Mozilla's tarball at build time, so there is no patched copy of Gecko to carry forward at each release. Same engine, same extensions, same Sync, and a profile directory of its own so it never touches a Firefox install.

The one default I take out of everything I ship. G1 Extended has no account and no server to send to — the phone talks to the glasses and stops there. The CMS loads no third-party script: no CDN, no font host, no analytics tag, so a visitor's browser only ever contacts the site they typed. Start Browser's branding folder is, literally, the preference file that switches Mozilla's telemetry, health reports, Shield studies and sponsored content off, and points the update links at my own releases. VectorFix reads map data that is already on the device, and has no network code at all.

It is the goal, not a feature I bolt on at the end — I want to live without all this surplus data, mine and anyone else's. Software that collects nothing has nothing to lose, nothing to sell and nothing to explain, and that is worth more to me than a dashboard of usage numbers I would never open.

Plain READMEs that state what fails as clearly as what works — the VectorFix one opens with "the core hypothesis is not yet validated", because that is the useful sentence. Commit messages in the present tense that say what changed and why. A preference for the version with fewer moving parts, even when it costs more work up front.

The rest of the toolbox: SEO, brand and campaign work, video production and interviews for the IUT Troyes Web TV, and enough English to ship documentation in it.
