  • Minds Beez
    Product Builder - AI, Web App Automation and Applications
    DIGITAL AND IT
    July 2025 - Today (1 year)
    Aix-en-Provence, France
    Minds Beez, on Mathias's side, designs and implements systems that automate your operations and connect your tools (no-code/low-code + code when necessary), with a touch of pragmatic AI. The idea: transform manual tasks into reliable and measurable workflows, delivered quickly, documented, supervised (logs/alerts), and designed to evolve. We start by understanding your processes, prioritize by ROI, deliver quick wins, then scale properly.

    What you gain:

    Time: less manual work, more value created.

    Quality: fewer errors, traceability, and compliance.

    Control: centralized data, useful KPIs and dashboards.

    Peace of mind: robust systems, maintenance, and skills transfer.

    Typical examples: synchronizing CRM/ERP, automating invoice and document processing, generating reports, orchestrating notifications and integrations between apps, or building a small business app where a link is missing.

    In short, Mathias is your product builder-integrator: he designs, connects, automates, and monitors to help you gain speed, reliability, and clarity.

    ENERGY AND UTILITIES
    January 2014 - June 2023 (9 years and 5 months)
    Saint-Paul-lès-Durance, France
    Digital-oriented HSE Engineer (nuclear/energy), I design and deploy web tools, dashboards, and workflows to ensure safety and compliance. At ITER (via Apave) and then on industrial sites, I created an HSE website (SHS website) centralizing procedures, lessons learned, and reference documents, and I structured the management: observation pipeline, safety flash, and monthly/annual reporting.

    I industrialize processes 92/94 (safety induction, permits, prevention plans, operating procedures, accident analyses) with templates, statuses, and histories to track each validation. I write procedures, review site documents, participate in Design Reviews, and verify regulatory applicability. On the ground, I conduct site visits, toolbox talks, and audits, feed the system with qualified findings, and manage the continuous improvement loop.

    On the data & dashboards side, I model key entities (HSE events, actions, risks, external companies, documents, training) and build KPIs: LTIFR/TRFR, near misses, action deviations, audit gaps, prevention plan status, open points in Design Review, regulatory coverage, subcontractor/qualification compliance, work and environmental risks. I integrate field data flows to measure reality, detect trends, and prioritize actions.

    For subcontractors, I design a tool-assisted approval process (criteria, documents, deadlines, follow-ups, scoring) and secure site access. I organize information and training for supervision and work management teams (training paths, certificates, proof), with traceability and automated reminders.

    My value: translating HSE requirements into simple and adopted products, combining field UX, data governance, and automation (no-code/low-code & BI). Goal: a readable, measurable HSE system that accelerates decision-making, reduces risks, and facilitates compliance, from design to execution and decommissioning.
