Some kind of baggage.
OPS/DevOps:

Cloud infrastructure:
AWS
Modern virtualization platforms Qemu/KVM/Proxmox/HyperV. 
Ansible for delivery and automation.
Jenkins + Gitlab+webhooks for CI/CD process. 
Configuring and supporting Internal Gitlab and Docker registries.

DevOps and System administration/architect tasks are my primary interests today. I have experience with all modern stacks of relative technologies like AWS Clouds, Docker, Kubernetes, ELK stack, and so on. I made a deep-diving for building and scaling Kubernetes clusters, with cloud or the on-premise and bare-metal decisions. Using Jenkins with Gitlab integration. I have experience in researching and migrating from monolith and legacy projects into container-based ecosystems. Also, a lot of different experience in system administration and Ops tasks previously.
I have knowledge of high-traffic networking and load balancing technologies. I use Python and Bash on a regular basis for system administration and DevOps tasks. I created and configured different kinds of monitoring systems and metrics collecting, using Grafana, TICK stack, ELK, and Prometheus. Also Ansible for deploying and automation tasks.
Interest really hard projects and challenges with good friendly teams.
