About Gaël

I intervene in consulting and transition management Supply Chain on missions ranging from a few days to several months to stabilize, manage, or turn around a situation or project: digital project management, continuous improvement, etc.

I support teams to unblock critical situations, optimize processes, and structure a simple, robust, and operational organization.

I am capable of managing an engaging and effective change process by empowering teams.

I provide rapid diagnosis, resolution of blockages (shortages, inventory, forecasts), coaching of business teams, reliability of results, and implementation of effective and sustainable routines.

Experience

  • Exotec SAS
    Independent Supply Chain Consultant
    LOGISTICS AND SUPPLY CHAIN
    July 2025 - January 2026 (6 months)
    Croix, France
    Context:
    • EXOTEC's Service Centers had high inventory levels, varying by site, and a poorly harmonized procurement strategy.
    • The DDMRP tool was underutilized, and teams applied different practices, leading to overstocks, shortages, and poor visibility of actual needs.

    Objectives:
    • Define and deploy a global inventory reduction strategy.
    • Ensure reliability of procurement parameters.
    • Harmonize operational practices across the entire network.
    • Improve and stabilize the main KPI (On Time Delivery) -> return to 90%.

    Action Plan:
    • Comprehensive review of inventory management strategy and mapping of local practices.
    • Optimization of the DDMRP model: recalibration of buffers, improvement of the forecasting model (linear regression, exponential smoothing), process audit, and correction of deviations.
    • Creation of new standardized processes and facilitation of training sessions for all Supply & Service Center teams.
    • A3 PDCA on the OTD project and management of continuous improvement actions.

    Results Obtained:
    • Measurable reduction in global inventory levels while securing availability (-25%).
    • Improved forecast accuracy and reduction in critical shortages.
    • Harmonization of practices and skill development of teams, enabling more robust and consistent management.
    • Improvement of OTD (50% of the path completed) and empowerment of stakeholders on subsequent actions.

  • JULES
    Independent Supply Chain Consultant
    RETAIL (LARGE RETAILERS)
    November 2024 - June 2025 (7 months)
    France
    Context:
    • JULES wanted to undertake a global transformation of its Supply Chain and needed to align its logistics operations with new omnichannel challenges.
    • Projects were numerous, scattered, and lacked clear transverse management, which slowed down execution and limited operational gains.
    • It was necessary to clarify the current situation (diagnosis) and the target (recommendation).

    Objectives:
    • Identify, structure, and manage priority supply projects, while initiating a continuous improvement dynamic to ensure flow reliability and reduce inefficiencies.
    • Conduct a complete Supply diagnosis (organization, process, tools), in line with the Vision.
    • Propose a target organizational, process, and tool structure for the Supply scope.

    Action Plan:
    • Mapping of existing Supply projects and qualification of their impact on the transformation.
    • Selection and prioritization of high operational ROI projects (e.g., End to End Supply dashboard).
    • Implementation of project management: scoping, planning, governance, progress meetings.
    • Deployment of continuous improvement projects (Lean, problem-solving, standardization).

    Results:
    • Clarified and managed project portfolio, enabling faster and more consistent execution (on Monday).
    • Identified and secured operational gains on key logistics flows.
    • Progressive adoption of a continuous improvement culture within the teams.

  • KIABI
    Demand/Supply Planning Leader
    April 2021 - November 2024 (3 years and 7 months)
    Hem, France
    Context:
    • I joined the position during a complete company transformation: Offer, IT, Performance, Omnichannel Commerce, Supply, etc.
    • Teams had not been managed for 2 years.
    • The role of buyer was supposed to disappear (replaced by future tools).
    • Overall performance (inventory, product availability, volume visibility, ...) was declining.

    Objectives:
    • Stabilize, secure, and relaunch the Supply function.
    • Redefine a target Supply Chain model (organization, process, tools) capable of supporting Kiabi's global transformation: omnichannel, Marketplace, second-hand, Offer, IT, Performance.
    • Re-establish reliable performance management (inventory, availability, volume visibility) to bring Supply back to the expected level.
    • Engage and onboard the business ecosystem in the transformation, ensuring buy-in, skill development, and change management.
    • Sustainably equip the Supply chain with a modern APS (Relex) to ensure reliable decisions and improve economic performance.

    Action Plan:
    • Define recommendations and target supply: organization, process, tools (functional requirements).
    • Onboard business teams and their ecosystem (omnichannel commerce, Offer, ...) and implement change management from the project's inception (information, appropriation, and roadmap challenge workshops).
    • Validate CAPEX and OPEX.
    • Drive, as sponsor, the project launch and monitoring.
    • Measure and adjust the trajectory based on results.

    Results:
    • 100% buy-in from business teams and the ecosystem on the evolution of roles.
    • Process: mastered through a versatility matrix.
    • Tools: replaced by APS (Relex). 100% functional coverage, reduction of in-store inventory, and increased product availability.

    Kiabi achieved its best year in history in 2025 in terms of revenue and results.

I had the pleasure of working with Gael for six months as part of the development of our maintenance business in several regions worldwide. Gael integrated seamlessly into the team and demonstrated exemplary professionalism. He brilliantly led his project for global and local inventory optimization, based on consumption analysis, lead times, and the creation of a high-performance forecasting model. He not only met but exceeded the set objectives, while delivering sustainable tools and training the teams. Gael also contributed to the implementation of management dashboards and led a major project to improve On Time Delivery, structuring a solid methodology and effectively mobilizing the teams. I highly recommend Gael for his expertise, rigor, and ability to drive initiatives forward in a concrete and collaborative manner. He is a real asset to any supply chain or continuous improvement project.
