The first scalability problem in any SaaS product isn't infrastructure. It's the codebase.
An application doesn't scale when cognitive overhead grows faster than the code.
Here's what that looks like in practice:
→ Every new feature requires changes in 4 different folders
→ A developer needs 2 hours of context before they can touch anything
→ Two developers working on different features keep breaking each other's code
→ Nobody knows where "the logic" actually lives
Feature-Driven Architecture flips the default approach:
Instead of organizing code by technical layer (all components in /components, all state in /store, all helpers in /utils), you organize by feature.
Each feature is a self-contained unit: its own components, state, helpers, types, and tests. One folder. One entry point.
Why this matters for founders:
When I build an MVP and hand it off to your team, I want them to be productive on day one. Not lost in a codebase where understanding one feature requires reading six folders.
Every Build Plan I deliver includes this principle: the architecture should match how your team thinks, not how a framework tutorial is organized.
Clean handoff isn't just documentation. It's structure.
