I am a senior engineer with 28 years of experience, 18 in IT and 10 in the Telecom sector. In 2017 I saw the need to refresh my IT skills and started learing current Agile and DevOps methodologies and Python language. In 2020 I studied Amazon AWS, but then got an appealing offer to work as contractor for IBM on a special project. I have been working for IBM in what has become now the EU Team for the Cloud Object Storage in the last 5 years, and in the first 3 years we worked also on the deployment, testing, troubleshooting and upgrade of the cloud native service KeyProtect for this special project. I have a great experience with Linux, UNIX and Windows systems, a bit less on Mac. I know programming languages: C,C++ and some Python, and I can write script for any Linux/Unix shell and have some experience with Powershell on Windows systems. I know a wide set of technologies, and security is a paramount.
