Infrastructure Analyst & Network Automation

Networks meet code. I build tools that automate the impossible —
from the command line to production dashboards.

Who is Ozumaru?

Working with network infrastructure since 2017 — constantly evolving in the world of automation and programming. I learned Python to solve real day-to-day problems and now I share that journey.

My focus is the NetDevOps space: combining network knowledge with software development to build solutions that scale. Ansible, Netmiko, FastAPI, NetBox — tools I use at work every day.

Beyond projects, I run a YouTube channel where I share technical content about network automation — because the best way to learn is by teaching.

"I am reborn with every challenge. The world may try to bring me down, but every fall is just the moment I awaken a new power. I don't walk… I advance."
