About Gilles

Are you running an SME and your information system is hindering your growth rather than supporting it? Are your teams wasting time on Sage 100, your data is difficult to leverage, and you don't have the resources to hire a full-time CIO?
This is exactly where I come in.
Independent IT consultant with 25 years of experience, I manage the information system of industrial and commercial SMEs as an outsourced CIO. My operational expertise on Sage 100 (Accounting, Commercial Management, Fixed Assets, Payment Methods, Payroll) allows me to intervene in both IT strategy and on the ground, without intermediaries.
What sets me apart: I worked as a chief accountant before becoming an ERP consultant. I speak the language of your CFOs and your finance teams, not just that of IT professionals. The result: projects that succeed, users who adopt, and an IS that truly serves your business.
What I concretely work on: Sage 100 audit and optimization, ERP configuration and migration, daily management of your IS, IT provider management, team training, and management support for technological choices.
Based in Brittany, I work in the Grand Ouest region and throughout France on-site.

    Outsourced CIO
    DIGITAL AND IT
    April 2021 - January 2026 (4 years and 9 months)
    Lannion, France
    As part of a long-term outsourced CIO mission for a composting equipment manufacturer (industrial SME, Côtes-d'Armor), I took charge of the entire management of the company's information system. My mission covers the definition and execution of the IT strategy in direct liaison with senior management, the supervision of network and server infrastructure (Active Directory, VPN, OVH cloud backups), as well as the management of external IT providers.
    I implemented an IT asset management system via GLPI, secured remote access for teleworking teams, and managed several IT security incidents, including a critical saturation of the backup infrastructure. I also support management on IT system evolution choices, drafting specifications, and selecting providers. This mission illustrates my ability to operate as a true CIO for a strategic, operational, and available industrial SME.

    DIGITAL AND IT
    January 2011 - January 2020 (9 years)
    Saint-Brieuc, France
    Managed and developed an independent IT consulting firm for 9 years. I led consulting missions, created a Sage 100 competence center, and implemented and supported Sage 100 for a portfolio of regional SMEs in the industrial, agricultural, commercial, and service sectors. My interventions covered the entire project cycle: needs assessment, writing functional specifications, multi-module configuration
    (Accounting, Commercial Management, Payroll, CRM), key user training, and post-launch support.
    – In parallel with ERP missions, I provided outsourced part-time CIO services for some clients: IT infrastructure supervision, relationship with hosting providers, incident management, and advising management on IT investments. This dual role of ERP consultant and proximity CIO forms the core of my current positioning.
