From recent cohort notes
“The dependency-loop lab mirrored a ticket I fought for weeks. Finally someone drew the graph on paper first.”

We keep drills close to the tickets you already see: stuck units, noisy disks, and bridges that need calmer language. Each desk bundle pairs paper diagrams with commands so muscle memory survives the walk back to the office.

Inside each desk bundle
Concrete sequences instead of slide fog
You receive annotated command transcripts, rack photos from the classroom, and quiet hours scheduling that respects Korea-time night shifts. Mentors grade your documentation, not your typing speed.
Paper-first diagrams
Draw before typing so bridges stay legible when VPNs flake.
Runbook snippets
Each week ends with a snippet sized for paste into your internal wiki.
Mentor office hours
Bring anonymized configs; we critique without recording your employer names.
The flow
Three beats we repeat every cohort
No numbered halo circles—just a rhythm you can hum.
01 — Calibrate
Baseline inventory on paper
We list dependencies, owners, and blast radius before touching production-like labs.
02 — Stress
Fault injection with a scribe
Pairs rotate facilitator and scribe so nobody hides behind keyboards.
03 — Publish
Evidence packet for your manager
You leave with photos, command logs, and a short narrative suitable for internal quality standards.

Masonry of honest notes
Mixed lengths on purpose.
“journalctl filters alone were worth it. I keep the printed cheat sheet taped inside my locker after Linux Service Boot Camp.”
Rina · Regional logistics desk
“Warm transfer simulation exposed how curt I sounded when tired. Bridge timers now live in our channel topic.”
Heejun · Incident drills cohort
“Short.”
Minseo · Desk technician
“Canary header exercise mirrored our blue/green debates. Still sorting slow start for JVMs, but probes finally match reality.”

Desk questions we actually hear
Do you ship certificates automatically?
We issue completion summaries after attendance and lab checkpoints clear—no overnight credential mills.
Can my whole support pod sit together?
Yes, we reserve adjacent racks when you note it during intake so pairs can whisper without derailing the room.
What is not bundled?
Exam vouchers, vendor appliances, and airfare for pop-up cities stay outside tuition so pricing stays readable.
Download the syllabus packet
We send PDF outlines for up to three programs so procurement can compare scope without sitting through a sales deck.
No countdown clocks—responses aim for two business days.
