Make real-world system design practice feel welcoming.
Nodivex exists to help engineers build confidence through hands-on practice. System design is learnable when you can experiment safely, see feedback immediately, and talk about trade-offs without fear.
Why practice-based learning works
Short, scenario-driven exercises help you experiment quickly. The simulator makes trade-offs visible so you can explain your thinking and learn from each run.
Juniors, mid-level engineers, aspiring seniors, and tech leads who want to practise without the pressure of a live incident.
If you want to experiment safely, see feedback, and get comfortable explaining trade-offs, you are in the right place.
Practice, learn, and iterate without pressure.
Katas are structured as low-stakes drills with clear briefs, so you can try designs, reset, and compare approaches without risking production.
You learn fastest by doing. Each kata lets you sketch, simulate, and iterate so you can see how systems react to your choices.
Feedback highlights what is working and what might struggle. Look for the bottleneck, then try one change and re-run.
Open a kata, tweak the diagram, and see how the simulator responds. We are cheering you on.
