🏛 Thinking in Architecture — Designing Scalable, Maintainable Systems

Architecture isn’t just for large enterprises — even small apps benefit from good structure. Here’s my approach.

📐 Patterns I Rely On

• Clean Architecture — separates business rules from infrastructure.
• Event-Driven Design — use message queues (BullMQ, RabbitMQ) for scalability.
• CQRS + Event Sourcing — when auditing and history tracking are essential.
• API Gateway — unify and secure access to microservices.

🔑 Key Principles

1. Modular Monolith First — split into services only when necessary.
2. APIs as Contracts — design them for other teams, not just your own.
3. Observability Is Part of Architecture — logs, metrics, and tracing are non-negotiable.

⚡ Lessons Learned

• Premature microservices = unnecessary complexity.
• Event-driven systems scale better for real-time use cases.
• Documenting architecture is as important as designing it.
