Most systems look great on paper.

But break the moment real traffic hits.

I learned this the hard way—spending weeks on architecture diagrams that fell apart in production.

Here's the mental model that changed how I approach system design:

1️⃣ Start with requirements, not tools
2️⃣ Design for failures, not just success
3️⃣ Think about trade-offs BEFORE you code
4️⃣ Question scale and constraints early

The biggest lesson? System design isn't about finding the perfect solution.

Most devs think backend = APIs.
It’s not.
It’s:
• Efficient request handling
• Clean architecture
• Smart DB design
• Caching strategies
• Security
• Reliability under load
Great backend ≠ just code
It’s systems that don’t break in the real world.
Tools change. Principles don’t.

Most devs jump into microservices too early
Truth: most systems don’t need it at the start.
It adds complexity—network calls, harder debugging, data issues.
Start with a monolith. Scale when needed.
Right architecture > complex architecture.
