🧠 I've been working on a WhatsApp Shared Inbox project that has grown way beyond "just another frontend."
It includes:
Feature-based architecture
Shared API layer
Centralized state
Runtime diagnostics
Modular features
Realtime communication
Architecture verification phases
Technical audits before every major release
What surprised me the most is that React itself became a very small part of the challenge.
The real challenge became answering questions like:
How do you stop modules from depending on each other?
How do you prevent technical debt before it happens?
How do you keep the project understandable after thousands of lines of code?
I started spending more time designing folders, boundaries, ownership, and contracts than actually writing components.
At first, I thought I was "slowing myself down."
Now I realize I was actually building something I can keep maintaining for years.
Curious if anyone else had the same shift when moving from small apps to larger production projects.
