I made C++ coding problems where you build things like a mini Redis or a tiny interpreter — looking for feedback

I’ve been building a small platform with coding problems that are more “systems-style” rather than typical algorithm exercises.

The idea is to practice by building simplified versions of real components, but still in a problem format (input/output + tests).

Some examples:

* implement a Redis-like server (TCP + protocol parsing)
* build a tiny interpreter
* create a virtual filesystem
* write an expression evaluator

The problems are:

* runnable directly in the browser (no setup)
* open-ended (you decide design/architecture)
* supporting multi-file submissions

I’m trying to keep them doable in a few hours, not huge multi-day projects.

I’m curious what people here think:

* does this kind of problem feel useful for improving practical C++ skills?
* or would you prefer something more guided / closer to full projects?

Still early, so any feedback would be really helpful.
