Story
Built where integrations meet operations reality
PortalX Flow School started when our founders kept hiring analysts who could diagram flows but could not point to the API that actually moved inventory. We teach the seams: contracts, traces, governance memos, and the language ops teams use when something breaks at 22:00 KST.
Principles on the wall
Evidence over adjectives
Portfolios must include artifacts external reviewers can open.
KR context by default
Cases reference local retail peaks, logistics partners, and compliance idioms.
Cohort size as a feature
Eighteen seats keeps mentor feedback per person honest.
Say the quiet limitation
Every FAQ set includes what we intentionally do not cover.
