This led to deeper engagement with networking tradeoffs like WebSockets versus UDP, event ordering, and state reconciliation, which clarified abstract system design concepts through hands-on implementation. ## Content One thing I learned while building a real-time architecture board - [devscape.in](https://devscape.in) I initially thought the difficult part would be rendering the diagram. It wasn't. The difficult part was synchronizing state between multiple clients without making the UI feel laggy. That's where networking decisions started becoming much more interesting than the UI itself. WebSockets? UDP? Event ordering? State reconciliation? These are the parts of "system design" that become much clearer when you actually build something.
