About Guillaume

Hello and thank you for stopping by my page!

After 25 years in the industry (nuclear, steel, and petrochemicals), in all hierarchical positions, I quickly noticed, despite working for large groups, the lack of suitable software tools or, if they existed, their lack of adequacy with the reality on the ground or the user's needs. Complicated interfaces, jargon in menus unrelated to real technical terms, or even applications that didn't work!

Thus, by combining professional experience, the ability to unite, and my IT skills, admittedly acquired as a self-taught person, I have been able to develop very specific applications:

Industry:
- Management of shutdowns on petrochemical and refinery sites via the internet
- Scaffolding management (design -> acceptance -> use -> dismantling)
- Tool management
- Management of oil tank maintenance (study -> preparation -> monitoring -> acceptance)
- Management of cleaning work (study -> preparation -> monitoring -> acceptance)
- Personnel authorization management (international scale)
- Management of dynamic safety procedures for high-voltage electrical substations (national scale)
- Industrial waste management (documentation, driver routes via mobile app, recovery calculations, implementation with ministerial tool TrackDéchets...)
- Production/management tool for underwater ROV components.

Medical
- Management of psychiatric emergencies within 48 hours

Misc.
- Management of registrations/licenses/equipment for a football club
- Management sites for employee representative committees
- Virtualization of ticketing with e-commerce
- Restaurant websites, jewelry sales
- Treasury applications

My adaptability, versatility, determination, proposal strength, and the eclecticism of my experience are now at your disposal, see you soon!

    Mon projet de radio n'ayant abouti, et n'ayant "plus le temps" d'intégrer une école d'informatique, j'ai totalement changé de voie, l'industrie qui cherchait des mécaniciens, j'ai donc préparé 2 diplômes en parallèle.
