A well-designed modular monolith can offer clear boundaries, simpler debugging, and lower operational burden, and is often a better starting point than premature service splitting. Senior engineers focus on failure modes, tradeoffs, and asking what problem an architectural choice actually solves rather than chasing impressive diagrams. The piece also warns that AI-generated architecture suggestions tend toward unnecessary completeness, and that the engineer's job is to decide what is actually needed today. It closes with a promoted paid product for practicing system design interviews. ## Full article daily.dev links to this article rather than hosting it.

architecture that works is often far more impressive than a complex one nobody can operate. --- Tags: [#career](https://daily.dev/tags/career), [#architecture](https://daily.dev/tags/architecture),
