Case Study / Identity & Application Operations
Evicourse Accounts & Customer Operations
A centralized identity and customer-operations capability for managing users, organizations, permissions, and governed access across connected applications.
Implementation Profile
- Engineering Focus
- Identity, access management, and application operations
- Technologies
- OAuth 2.0 / OpenID Connect, role-based access control, REST APIs, relational data models
- Integration Model
- A shared identity and authorization boundary used by connected applications and services
- Implementation Status
- Internal implementation; selected provisioning and external integrations remain in validation
01
The Problem
Customer access, organization membership, permissions, service entitlements, and support activity can become fragmented when each application manages them independently.
A technical foundation was needed to keep tenant boundaries and authorization decisions consistent while allowing specialized applications to retain their own responsibilities.
02
The Engineered Solution
I developed a centralized account and customer-operations foundation for identity, organizations, memberships, roles, invitations, service access, support records, and portal administration.
The capability separates authentication and authorization from product-specific behavior, giving connected systems a governed way to confirm who a user is and what that user may access.
03
How It Works
- 01
Authenticate
Establish and verify the user identity.
- 02
Resolve Organization
Associate the user with an authorized tenant and membership.
- 03
Evaluate Access
Apply roles, permissions, and service entitlements.
- 04
Connect Services
Provide governed access to approved applications and operations.
04
Technical Implementation
The implementation uses explicit identity, tenant, role, permission, invitation, service, document, support, and billing-related boundaries. Automated tests cover authorization, tenant isolation, migrations, and database safety; external systems remain authoritative for their own records.
- OAuth 2.0 and OpenID Connect boundaries
- Multi-tenant organization and membership models
- Role-based permissions and entitlement checks
- REST API boundaries for connected services
- Automated identity, authorization, and tenant-isolation tests
05
Where This Capability Can Be Applied
Examples of how the engineering approach could be adapted; these are not claims of completed integrations.
Agency and employee portals
Apply shared identity and permission controls to internal applications.
Contractor and partner access
Govern access across organizational boundaries and defined roles.
Multi-organization service applications
Support customer operations while preserving tenant isolation.
06
Technical Evidence
The implemented foundation demonstrates identity, organization membership, authorization, portal administration, and tested tenant boundaries. Selected cross-system provisioning remains in validation.
Verified
Identity and tenant controls
Automated coverage exercises authentication boundaries, memberships, roles, permissions, and tenant isolation.
Implemented
Customer operations model
Customer, service, support, document, and access records have defined responsibilities.
In validation
Connected provisioning
Selected onboarding and third-party provisioning paths require live feature-by-feature validation.
07
Applying This Approach to Your Environment
This approach can be adapted to an existing application environment by defining authoritative identity sources, organization boundaries, permission rules, and narrow integration contracts before connecting services.
