Complex code is easy to write.Simple code is hard.
Over time, I realized:
Good systems are not “clever”
They are boringly predictable
Signs of clean backend systems:
• Clear data flow
→ You can easily trace how a request moves through the system (who calls what, in what order) without guessing or digging through multiple layers
• Minimal side effects
→ One function/service does one job, without unexpectedly changing other parts of the system
• Easy debugging
→ When something breaks, you know exactly where to look instead of chasing issues across multiple services
• Consistent patterns
→ Similar problems are solved in similar ways (same structure, naming, and design), so the system feels familiar everywhere
If only you understand your system,
it’s already too complex.
Simplicity scales better than brilliance.
