  • Panthor
    Infrastructure Takeover Audit
    DIGITAL AND IT
    November 2024 - November 2024 (1 month)
    Paris, France
    Audit of the technical infrastructure for a client.

    The IT service company that contacted me wanted a technical feasibility study for taking over a complex project consisting of a Ruby On Rails backend and two Vue.js frontends in the wine sales sector.
    The audit covered an in-depth study of the technologies used (versions, third-party libraries), the infrastructure (Database, data migration, production servers, deployment architecture), and code quality (quality metrics, test coverage).
    I also provided recommendations and an action plan for taking over the entire project in the simplest way possible.
    A deliverable was produced, summarizing all the above elements and incorporated into a presentation to the client to convince them of the viability of the takeover plan.
    The project was successfully taken over and transferred to the IT service company's new infrastructure.
