About Julien

With over 10 years of experience in research environments, I've transitioned from academic labs to a fast-growing MedTech startup, and finally founded my own company, SUFFISCIENS. My observation is consistent: brilliant scientific concepts often remain fragile prototypes due to the lack of appropriate software structure.

My role? To bridge the gap between scientific exploration and industrial rigor.

I help Deep Tech R&D teams transform their "artisanal" code (isolated scripts, notebooks, lack of traceability) into robust, maintainable, and scalable software. My approach doesn't stifle researchers' creativity; it creates the necessary framework for their research to become industrial-quality technological assets.

Why work with me?

Dual Expertise: My PhD/Engineering background allows me to understand your complex scientific challenges, while my software engineering expertise ensures the quality of your Python developments.

Open-Source Vision: As the founder of SUFFISCIENS, I developed nuRemics®, an open-source Python framework designed to structure R&D digital tools and foster multidisciplinary collaboration.

Commitment: I don't just code; I build a healthy software ecosystem with you that reduces individual dependency and secures your long-term growth.

My areas of intervention:
- Audit and structuring of Python R&D code.
- Software architecture for complex scientific projects.
- Implementation of best engineering practices (versioning, testing, documentation).
- Support for adopting the nuRemics framework.

    June 2024 - Today (2 years)
    Montpellier, France
    We are developing nuRemics®, a unified open-source framework designed to build scientific software tools, enabling industrial-quality technology research scaling. But a framework alone is not enough. SUFFISCIENS is the ecosystem that brings it to life, fostering a collaborative community and providing Deep Tech teams with the support and training needed to effectively integrate it into their R&D workflows.

  • EPF Engineering School
    Science Lecturer
    EDUCATION AND E-LEARNING
    September 2025 - December 2025 (3 months)
    Montpellier, France
    Practical scientific programming sessions in Matlab for engineering students.

    The course offers a progressive approach:
    › Introduction to the Matlab environment (workspace, scripts, programming basics).
    › Practical exercises and guided problem-solving to develop autonomy.
    › Introduction to Simulink and Simscape for system modeling and simulation.
    › Implementation of numerical methods, such as the Euler method, to solve engineering problems.

    My role is to guide students of various levels, enabling them to acquire practical programming skills and the confidence needed to apply digital tools to engineering challenges.

  • Mercor
    Computer Science Expert
    RESEARCH
    September 2025 - October 2025 (1 month)
    Montpellier, France
    I leverage my scientific expertise and analytical skills for innovative projects through the Mercor.io platform.

    Mission: Design expert evaluation questions for AI.

    I participated in a project aimed at identifying the limitations of advanced AI models when faced with questions requiring deep and highly specialized expertise. The objective is to create a series of HLE-type questions, based on research papers, that:
    › Are self-contained, integrating all necessary context within the question itself.
    › Require a short, unique, and unambiguous answer.
    › Rely on specialized concepts from arXiv, bioRxiv, or ChemRxiv articles.
    › Are designed to challenge even the most advanced models (like GPT-5), demanding expert reasoning rather than simple knowledge recall.

    These questions serve as a scalable evaluation tool, allowing AI researchers to measure and track model performance in specialized reasoning. My role involves crafting these expert questions within my specialty, ensuring they meet the project's rigorous requirements.
