Context

The problem and its boundary.

Migration and integration architecture spanning API Gateway, Lambda, VPC networking, event processing, authentication/authorization, payments and CRUD APIs.

The restored board is in Alexsandro's authenticated corpus and was last modified by him; the frames are dated September 2022.

No explicit in-frame role credit or production-result evidence was observed.

What this archive can prove

Published authorship. Claims proportional to the source.

  • No repository, public deployment link, before/after metrics, date or post-migration result is present.
  • The page does not separate completed implementation from roadmap/proposal scope.
  • The MRG cover is duplicated across another Notion case and should not be treated as unique evidence.

Auth Architecture

MRG · AdmitONE Original · Okta

The application could not complete /logout in Okta and therefore could not reliably close the Okta session. The proposed design keeps Okta as the user-management source of truth, changes existing flows minimally and avoids storing passwords.
