NEXUS

NEXUS is a production-oriented SaaS platform for commerce operations.

It manages:

• Organizations
• Users
• Products
• Customers
• Orders
• Inventory
• Payments
• Fulfillment
• Notifications
• Reporting

The project is intentionally built as a long-term engineering journey.

The goal is not to demonstrate how many technologies can be used.

The goal is to explore:

• Software architecture
• Domain modeling
• System design
• Scalability
• Distributed systems
• Reliability
• Observability
• Infrastructure
• Security
• Performance
• Technical decision making

Architecture Evolution

NEXUS evolves through several architectural stages:

1. Modular Monolith
2. Production-ready application
3. Horizontally scalable system
4. Event-driven components
5. Distributed workloads
6. Observable production system

Engineering Principles NEXUS follows a few principles:

• Prefer simplicity over unnecessary complexity.
• Measure before optimizing.
• Make architectural decisions explicit.
• Keep business logic independent from infrastructure where practical.
• Test important behavior.
• Design for failure.
• Document trade-offs.
• Introduce distributed systems only when there is a real problem to solve.
