Freelancer profile translated to English.

Description

With over 20 years of experience in infrastructure project management, I have developed solid expertise in overseeing complex cross-functional projects, including migrations, transformations, carve-in integrations, and infrastructure optimizations/consolidations, whether on-premise or in the cloud. A significant portion of my experience has been dedicated to the technical integration of subsidiaries, where I have led large-scale projects aimed at harmonizing and consolidating information systems between multiple entities.

I have advanced technical skills in areas such as AWS cloud (Practitioner certification), Azure, Windows, Linux, MS SQL, Oracle, and LAN/WAN networks, which allows me to support, interact with, and challenge teams of technical experts to achieve the set objectives.

My expertise also extends to the application of various project management methodologies, including Agile, hybrid, and classic (PMP), with a marked preference for hybrid approaches, which are particularly well-suited to infrastructure projects.

My daily rate is ~300€ for assignments longer than 3 months and ~400€ for those shorter than 3 months.

Best regards
