I'm a Senior Systems Engineer involved in the cloud, infrastructure, containers and security things. Sometines I do some coding using Python mostly, but also used Ruby in the past.
I also have an AWS Certified SAA. My credential ID is MGXS1HVKB1VEQX9L and it's valid until March 2021.
Time to time, I spent my weekends doing something I like to call "Weekend Lab", where I study new technologies/tools/whatever using a "lab" approach. I try to document them as better as I can.
