About Henri

I design and secure real-time architectures built to last for years of production, not just to impress in demos.

For over 12 years, I've worked on critical 3D systems: multi-platform Unity projects, medical simulations, VR/AR environments, and industrial applications. My role: lay technical foundations that absorb complexity instead of collapsing under its weight.

I step in when the technical challenge becomes strategic. A project accumulating debt. An initial architecture that can no longer handle the load. A team moving forward but lacking a structuring vision. These situations require more than an extra developer; they demand an eye capable of diagnosing, restructuring, and putting the project back on solid rails.

My areas of expertise: real-time systems architecture, technical safeguarding of drifting projects, AI integration into production pipelines, and guiding teams on structuring choices.

Generative AI is part of my daily routine: automation, asset generation, agents. I integrate it into workflows without sacrificing robustness. You gain speed, not fragility.

I work remotely on in-depth missions, providing full technical oversight or strategic support to an existing team.

Have a project to secure or an architecture to design? Write to me.

    Unity Developer | UI, Gameplay & Real-time
    VIDEO GAMES AND ANIMATION
    February 2023 - Today (3 years and 4 months)
    Marseille, France
    At Cross The Ages studio, I participate in the development of a multi-platform project (mobile and desktop), working on subjects with a strong real-time, user interface, and game experience component.

    My role covers cross-functional aspects of the project, including:

    - Advanced UI development and integration of complex, user-oriented interfaces,
    - Implementation of gameplay mechanics and interactive systems,
    - Design and optimization of shaders, VFX, and real-time rendering,
    - Adaptation and optimization of features for cross-platform constraints (mobile / desktop).

    I work in close collaboration with the design, art, and technical teams, with a particular focus on execution quality, code maintainability, and long-term performance.

    Beyond implementation, I contribute to technical decisions, system structuring, and maintaining a robust foundation that allows the project to evolve smoothly.

    December 2020 - February 2023 (2 years and 2 months)
    Bordeaux, France
    At APPERTURE, I participated in the development of Unity solutions for educational and training applications, with a strong emphasis on 3D simulation and professional use cases.

    My role consisted of:

    - Designing and developing an internal Unity framework, intended to facilitate and accelerate the creation of educational applications,
    - Working on medical training 3D simulations, integrating strong constraints of reliability, clarity, and performance,
    - Mentoring and supervising a team of junior developers, on both technical and methodological aspects,
    - Contributing to AR, VR, mobile, and WebGL projects, adapting solutions to the constraints of each platform.

    I also maintained continuous technical watch, to anticipate engine evolutions and guide technical choices with a focus on longevity and maintainability.
