About Thierry

Is your business software stuck? Let's upgrade it.


Has your PHP application become a "gas factory" that no one dares to touch anymore? Or are you building a robust tool for **Construction**, **Agriculture**, or **Industry**?

I am a **Symfony Architect & Expert**, specializing in difficult contexts: where standard software fails, I build custom solutions.

My method? Digital **"Restomod"**.
I don't throw away your existing system. I preserve your business logic and replace the sluggish engine with a high-performance one (Symfony, PostGIS, DDD Architecture).

My Expertise in 3 Pillars

🎯Pillar 1: Legacy Modernization & "Restomod"

*Audit & Rescue:Taking over aging applications (technical debt, slowness, bugs).

*Extreme Performance:Accustomed to massive volumes (e.g., optimizing30 million linesof viticulture data, going from 60s to instantaneous).

*Migration:We fix the engine while driving, without stopping your production.

🏎️Pillar 2: Complex & Field Architecture

*Coder, but not afraid:Whether it'sAsbestosregulations (Construction) or vineyard management (Physiocap), I adapt to your field reality.

*Robust Solutions:Tools designed for the end-user (offline mode, simple UI, robustness).

*Advanced Mapping:**PostGIS / GIS** expert for visualizing your data.

🏗️Pillar 3: Symfony Development & Solid Architecture

*Clean Code:API Platform, DDD, SOLID. Tested and maintainable code.

*Business Vision:I code so that your tool is profitable and sustainable for 10 years.


Is your project a "five-legged sheep"? Even better.

I prefer five-legged sheep to showcase websites. If you're looking for a technical partner who isn't afraid to get their "hands dirty" (literally and figuratively), we're meant to get along.

Experience

  • Personnel - CIVC
    Physiocap Evolution
    WINE AND SPIRITS
    January 2026 - February 2026 (1 month)
    Lyon, France
    This project involves updating the Physiocap project for which I was providing SAV (After-Sales Service).

    This project allows clients who have purchased the Physiocap device to map vine shoots to derive data for improving vine quality and yield.
    Before the update, the client uploaded data from the sensor and then had to use complex open-source tools, understand them, and try to exploit the data.

    After the update, data is still uploaded but is directly displayed on the web application, with filters and settings available.

    Project migrated from Laravel 6 / Blade / MySQL to Laravel 12 / PostgreSQL / Martin / Vuetify. All of it has been put under Docker.

    For information, Martin is an adaptation of MapLibreGL.
