Sebastian Popity

Just a regular dude with a not-so-regular schedule.

By day, I'm a network design engineer at AT&T, helping customers around the world get connected and stay connected. I plan how the pieces fit together, fix whatever refuses to cooperate, and write the documentation everyone ignores until something breaks.

After hours, the home lab is my playground: building automations, wiring up AI agents and breaking things on purpose, so they don't break by surprise in production.

Before and after that, I'm a husband and a father, which is the job with the strictest SLA and no maintenance window.

Whatever free time is left (roughly a /30 of the week) belongs to my three besties: a road bike, a gravel bike and an MTB. I pick one, go ride, and then write about it on my blog or post it on the gram. The other two pretend they don't mind.
