Software design patterns, system design, and architectural decision-making.
Architecture is about making the right trade-offs. This section covers patterns, principles, and real-world case studies to help you design resilient, scalable systems.
Divide your system into distinct sections, each addressing a separate concern.

monolith · enterpriseServices communicate through events — loose coupling, async processing.
async · scalableA non-proprietary case study to evaluate architectural concepts and framework decisions.
case studyWhen choosing an architecture, consider:
| Factor | Monolith | Microservices | Event-Driven |
|---|---|---|---|
| Team size | Small | Multiple teams | Multiple teams |
| Deploy frequency | Low–Medium | High | High |
| Complexity | Low | High | High |
| Latency | Low | Network-dependent | Async |
| Data consistency | Easy | Hard (distributed tx) | Eventual |
| Scaling | Vertical | Horizontal per service | Horizontal per handler |
Start simple. Extract services only when you have a clear reason — team boundaries, independent scaling, or deploy cadence.
Services communicate through events for loose coupling and async processing.
Organize your application into presentation, business logic, and data access layers.
Independent services communicating over well-defined APIs.
