What he does

Six jobs.
One on-call rotation.

He handles the operations work that wakes your engineers at 3 a.m., so they stay on architecture.

01He answers pages

First on-scene in 90 seconds.

The moment an alert fires, Theo picks it up, opens the logs and the last deploy, and posts a first explanation in your team chat. With the evidence, not just the alert.

  • Picks up alerts before your team wakes up
  • Starts an incident chat with everyone who needs to be there
  • Pulls the failing log line straight into the conversation

02He SSHes and fixes

Runs your runbooks, step by step.

Theo connects to your servers the same way your engineers do safely, through the keys you trust. He follows the steps from your runbook: read the logs, restart what's stuck, bring back the previous version if needed.

  • Only touches what you allow · no surprises
  • Shows you the plan before doing anything risky
  • Every action recorded · you can replay any night

03He unblocks CI

Failed pipelines triaged in minutes.

When the build breaks, Theo reads the error, tells whether it's a real bug or a random one, and either reruns or proposes a fix on the spot. Your team stops waiting and ships.

  • Tells real failures from random ones
  • Proposes a fix with the exact steps to reproduce
  • Reruns the build and announces when it's green

Plus, he also

Rolls back a bad release

Spots when a deploy broke something, brings the previous version back.

Cuts cloud costs & alert noise

Finds unused servers. Mutes alerts that cry wolf. Sends you a weekly recap.

Writes the post-mortem

Clear summary after each incident: what happened, why, what to fix next.

ROI

The math is uncomfortable.

He covers an on-call rotation that costs you a $140K SRE · for the price of a coffee subscription.

Cloud bills creeping. Alerts crying wolf.

Your cloud spend is going up. Your team ignores half the alerts because too many are noise.

12% cloud savings month-over-month. Real alerts get the attention again.
