Why "Simple" Architecture Wins Long Term

2025-10-18 | Product & Engineering | by DJC AI Team

Complexity is the enemy of execution.

Junior engineers love complexity. They want to use Kubernetes, Kafka, GraphQL, and Serverless on a project that gets 500 hits a day. They want to show they are "smart."

Senior engineers love simplicity. They want to use a Monolith and a Postgres database. They want to show they can ship.

The Boring Stack

At DJC, we are proud users of "Boring Technology."

Postgres: It just works.
Monoliths: Easy to debug, easy to deploy.
Standard Libraries: No obscure chaotic dependencies.

Why Simple Wins

Debuggability: When something breaks in a microservices mesh, you need a PhD in tracing to find it. When something breaks in a monolith, you read the stack trace.
Onboarding: A new dev can run the monolith in 5 minutes. Trying to spin up 15 microservices locally is a nightmare.
Reliability: Fewer moving parts = fewer points of failure.

Reducing Cognitive Load

Your code is read 10x more than it is written. If your architecture requires a 2-hour lecture to explain, it is too complex.

We optimize for Cognitive Ease. Can a developer open the file and understand what it does? Can they make a change with confidence?

Simplicity scales.

Instagram was a monolith with millions of users. Stack Overflow runs on a handful of SQL servers.

Don't let Resume Driven Development kill your product. Build boring. Build simple. Win.
