I am focused on learning and growing in DevOps and system administration.
Learning DevOps since August 20, 2024. 🚀
My goal is to automate processes, build reliable and efficient systems, and be a valuable team member.
Currently sharpening skills in monitoring, containerization, CI/CD, Linux administration, and security.
Working as a 2nd line sysadmin at GK Arti.
