Description

Hello

I am Calogero Di Stefano, an enterprise architect with over 20 years of experience in information systems.

My career began as a Systems Engineer, where I acquired solid IT knowledge before specializing in architecture.

Throughout my career, I have had the opportunity to work both within digital services companies (ESNs) and with user companies. This diversity has allowed me to gain a global vision of IS, by intervening in various business sectors and on a multitude of projects.

What characterizes me during my assignments is the guarantee:

- of global and strategic support at each stage of the project, ensuring a clear and coherent shared vision,

- to provide informed advice, not only to meet their current needs but also to anticipate their future developments,

- to have an approach focused on a deep understanding of business challenges and long-term objectives,

- to identify vulnerability points and provide concrete recommendations to optimize the performance, security, and sustainability of systems,

- to ensure that the proposed solutions comply with current standards and regulations, thereby guaranteeing the security of data and systems.
