About Franck

You lead high-stakes programs: platform development, business application leveraging your data assets, or projects integrating AI.
To successfully scale adoption and user trust, it is essential to secure the fundamentals upstream: integration into business processes, data quality and availability, and relevance of architectural choices.
These decisions directly influence system scalability, longevity, and the cost of operational maintenance.
I design hybrid architectures combining distributed systems, data, and agentic approaches, drawing on proven as well as newer technologies, deployed in on-premise, PaaS, or Cloud environments.
My approach involves structuring truly production-ready solutions, integrating often underestimated dimensions: user experience, process automation, operability, deployability, scalability, and cybersecurity. The goal is not to produce an MVP, but to build solid and lasting foundations.
I support my clients end-to-end, from initial scoping to solution adoption, including architectural choices and development monitoring.
My expertise lies in the ability to make complex and heterogeneous technological environments coexist and interact effectively, even when they span different generations. This approach allows for both complete overhauls and progressive evolution paths adapted to technical and budgetary constraints.
Where many remain in a logic of technological stacking, I focus on building coherent, resilient systems aligned with business needs. The implemented solutions are levers for operational transformation, designed to be adopted and used sustainably.

Experience

  • Lursia
    President
    TECH
    November 2024 - Today (1 year and 9 months)
    Lursia is the structure through which I conduct my consulting and implementation activities on high-stakes technical systems.

    I support organizations (startups, SMEs, industrial environments) facing complex challenges involving software architecture, data, and AI integration.

    Lursia embodies an approach centered on the design of hybrid architectures, combining distributed systems, automation, and agentic approaches, with a clear objective: to build robust, operable, and scalable solutions.

    The missions cover the entire system lifecycle, from the upstream scoping and needs definition phases to production deployment and user adoption.

    Lursia is part of an operational transformation logic: the implemented solutions are designed to address concrete business challenges, not just technological demonstrators.
