Modules

  • Module 1 — Log anatomy
    Timestamps, device IDs, mutation IDs, and how partial uploads appear in Offline Wallet Sync Log exports.
  • Module 2 — Clock skew hygiene
    Spotting skew that masquerades as “later write wins” and documenting uncertainty honestly.
  • Module 3 — Conflict narration
    Templates for describing two offline spends claiming the same balance slice.
  • Module 4 — Orphaned queues
    Finding pending mutations that never acknowledged after a reconnect.
  • Module 5 — Limits & escalation
    What logs cannot invent, when to stop, and how to escalate without promising outcomes.

Instructor

Jiyoon Han designs sync literacy drills for product and care teams. Previously she documented offline reconciliation runbooks for a Seoul wallet platform and now teaches the habits that kept those runbooks usable.

Office hours follow Korea evening slots so Gangnam and remote learners can join without sacrificing sleep.

FAQ

Do I need to be an engineer?

No. Support leads and QA analysts succeed when they can read JSON-ish exports. We gloss technical terms in Module 1.

Will this teach me how to grow wallet balances?

No. Content is operational and educational. See Not Financial Advice.

What is a real limitation of this course?

We do not reverse-engineer proprietary binary formats. If your Offline Wallet Sync Log is encrypted opaque blobs, we can only help after you provide a decoded text export — and we will say so early rather than pretend otherwise.

How long does Fluency take?

Most Field Desk learners finish core modules in 8–12 focused hours, plus drills.

Course reviews

“The Module 4 orphaned-queue exercise matched a bug we had shelved for months.”

Short and slightly skeptical: useful templates, still light on multi-rail wallets. I would take an advanced appendix if it appeared.
