Enterprise ERP Platform
A reference architecture for internal enterprise systems — integration, access control, and audit trails handled as first-class architectural concerns.
Overview
This reference architecture illustrates how we approach enterprise resource planning systems: integrating with existing infrastructure, enforcing granular access control, and maintaining a real audit trail — not just building a UI over a database.
It is a technical pattern used to demonstrate our enterprise engineering approach, not a description of a deployed system.
This page is a Reference Architecture, published to illustrate our engineering approach. It does not describe a completed client engagement, and no client, metric, or outcome referenced here is real.
Approach
How This Demonstration Was Built
Enterprise ERP Platform is a reference architecture demonstrating how we'd approach this kind of problem — the reasoning below is real, worked through the same way an actual engagement would be.
Business Problem
- Departments work from different, sometimes contradictory versions of the same data.
- Legacy systems don't integrate, forcing manual data re-entry between tools.
- Compliance requirements need an audit trail that most internal tools don't have.
Technical Challenges
- Integrating cleanly with legacy systems that were never designed to be integrated with.
- Modeling role-based access control granular enough for real organizational structure.
- Keeping the system usable as more modules and departments are added.
Architecture Overview
A central data layer with clearly-owned domains per department (finance, inventory, HR), connected through defined internal APIs rather than direct database access.
An integration layer handles legacy system connections separately from the core, so legacy quirks don't leak into the main architecture.

Legacy Systems
Suggested Technology Stack
- NestJS
- PostgreSQL
- Docker
- Kubernetes
- SSO/SAML
Security Considerations
- Every action traceable to a specific user and role.
- SSO integration with existing identity providers rather than a separate login system.
- Field-level access control where compliance requires it, not just page-level.
Performance Strategy
- Department-specific data domains prevent one module's load from degrading another's.
- Reporting queries run against read replicas, never the primary transactional database.
SEO Considerations
- Internal system — not indexed. SEO applies only to any public-facing documentation.
Accessibility Considerations
- WCAG 2.2 AA across every internal-facing screen — accessibility inside a company is as real a requirement as accessibility on a public site.
Scalability Plan
- New departments/modules onboard through the same defined internal API pattern, not a special case each time.
- Horizontally scalable service layer per domain.
Future Enhancements
- Self-service reporting for non-technical department leads.
- Workflow automation layer connecting modules without custom integration work each time.

Frequently Asked Questions
Is this based on a real client project?
No. This is a Reference Architecture — a documented technical pattern we use to illustrate our engineering approach, not a description of a specific deployed system built for a client.
Can this integrate with our existing legacy systems?
Yes — the integration layer is specifically designed to isolate legacy-system quirks from the core architecture, rather than letting them shape the whole system.
How is compliance handled across departments with different requirements?
Access control and audit logging are modeled per data domain, so different departments can have different compliance requirements without one blocking the other.
