Generally, I provide Free/Open source solutions to various problems my clients might have. I manage servers, deploy clusters, document and record video HowTos and demos for the clients in order to help them lower their costs, have better security and an overally better experience with their deployments and software.
I've worked with several companies, freelancing, part time and full time.
My latest job was DevOps/Senior SysAdmin @ CloudSigma. I did all kinds of stuff there like:
Kubernetes deployments and maintenance(on premise)
Minio deployments and maintenance (on premise)
OpenStack deployments and maintenance (on premise)
OpenShift deployments for third parties (CS clients)
bash script automation
Puppet management
General GNU/Linux OS maintenance and troubleshooting.
Among other many things. I'm, also, a bit into Crystal/Go/Ruby development. I like some odd frameworks for web and I've done some CLI tools as well.
