What I build.

A portfolio of artificial intelligence products and SaaS built in France — Lima, Tako, Vigie.

Three flagship products, a few side projects. Everything below is live today — real applications or public landing pages, not mockups. If you want to see a product, open the link.

Nonprofit intranet · Pro bono
Idea, design, code, operations

Lima.The intranet of an improv theater company.

Preview of the Lima intranet: an improv show's page with its cast (performers, MC, music and tech crew) and attendance.
Product preview — a show and its cast

Lima gives a theater improv company a private space for its members — directory, calendar of shows and workshops, cast list for every performance, a library of formats and game cards, a collective memory of sketches, expense reports and email notifications (Brevo). Not a showcase site: a real internal working tool.

Built pro bono for the association: self-hosted on a VPS, deployed by script, with no platform dependency. It's also a way of keeping the promise — the members are at home, and their content stays home.

Access restricted to members of the association.

Concept, design, code

Tako.An app for communicating better.

Preview of the Tako app: the conversation list organised by bond — dating, family, friends, work — each with its icon and latest message.
Product preview — dating · family · friends · work

Tako helps people talk to each other better — in love (couples and online dating: Tinder, Adopte, Hinge), with family, between friends and at work. It helps you phrase what you really mean, and understand what the other person is really writing — without outsourcing your sincerity to a machine.

For every message, Tako delivers three beats: an analysis of what's at play, two replies calibrated to your style, and the why behind the reasoning — grounded in transactional analysis. Screenshot import via OCR, group conversations and a writing coach round out the product.

Idea, design, landing, product

Vigie.The safety register, always up to date.

Vigie's landing page: "Your safety register, always up to date", with a schedule of mandatory checks.
Live — landing + interactive demo

Vigie is the digital safety register for small category-5 public-access venues ('ERP' under French law) — restaurants, bars, shops. The law imposes a schedule of mandatory checks (extinguishers, gas, electricity, smoke extraction); most owners keep it in a dusty binder and hold their breath before the safety inspection. Vigie keeps the schedule, sends reminders before every deadline, and archives the reports in a vault that's ready to show.

Mobile-first, for an audience that lives on their phone. The landing page is live, paired with an interactive demo of the register; first professional meetings are underway. The sourced database of legal obligations (art. R. 123-51 of the French building code) is the defensible asset competitors don't copy.

On the side

The side projects.

The rest of the workshop. Agents and tools I built for myself — detectors, radars, demos. Not everything is on display, but everything actually runs.

  • 2026

    Immo-radar

    An alert channel for the best real-estate listings — up to 50% below market. A research agent that hunts down the property for you.

  • 2026

    boost-radar

    For bettors — or accountants: French sports bets with positive expected value, ROI > 5%. Capped at €10–20 a stake, alas.

  • 2025

    RAG Legal Demo

    A mockup of a legal assistant over a private corpus, to demonstrate a lean, no-frills RAG approach.

A product, a workshop, a helping hand? Let's talk.
