140+ architecture reviews logged—still counting
- Seminar tables for service boundaries, queues, and trace budgets—not slide marathons.
- Mentor rubrics borrowed from real platform teams across APAC cohorts.
- Failure drills that respect on-call reality in South Korea time zones.
Trusted by platform teams, senior developers, technical leads, and software architects who want concrete diagrams—not abstract slogans.
01
Signals from the field
We publish rubrics, workshop agendas, and observability sketches the way magazines publish features: paced, annotated, and ready to argue with.
Rubric-first reviews
Two reviewers per table, color-coded risks, explicit async edges—no mystery grades.
Scenario humidity
Failure drills include comms cadence, not just kubectl—because incidents are human+technical.
Diagrams you can steal
Canvas-sized templates sized for walls, not slide decks that die in PDF limbo.
Courses

Service design
Service Boundary Cartography
Map ownership seams, synchronous seams, and async handoffs before code freezes a wrong split.
Open narrative
Messaging
Messaging Choreography Lab
Design sagas, outbox patterns, and idempotent consumers with tabletop timelines instead of slide theory.
Open narrative
Caching
Cache Coherency Field Manual
Warm paths, stampede guards, and invalidation ladders with measured tradeoffs for read-heavy systems.
Open narrative
Resilience
Resilience Rehearsal Studio
Game-day scripts, bulkhead sketches, and graceful degradation paths with observability hooks baked in.
Open narrativeFrom our cohorts
Mixed formats on purpose—some names withheld, some quotes short, none copied from generic templates.

“Cache Coherency Field Manual TTL ladder survived our CFO walkthrough—rare.”
Pull quote
“Messaging Choreography Lab tabletop poisoned-message drill is now a quarterly ritual.”

“Trace budgets finally fit on one page.”
The cohort spine
Five beats, not four circles—each beat has artifacts you can bring to your next internal review.
-
Week 0 — intake map
Submit anonymized diagrams; mentors annotate ownership seams.
-
Week 1 — async ink
Paper choreography before any broker vocabulary enters the room.
-
Week 2 — stress overlays
Traffic shapes + cache TTL ladders on shared walls.
-
Week 3 — failure voice
Game-day scripts with comms cadence and observability spine.
-
Week 4 — gallery walk
Peer critique with rubric scores, not vibes.
Notebook dispatches
Field notes from mentors—short, technical, and occasionally opinionated about trace budgets.

Drawing queues before choosing brokers
A broker name on a slide is not architecture. Start with delivery semantics, then let infrastructure follow.
