Inside the systems workshop.
Try a decision, follow its consequences, explore another approach.
Your call.
The product changed. The system hasn’t caught up. Make three calls, see what follows, then try another approach.
Three decisions. Different outcomes. Replay to explore another approach.
Put the system
under pressure.
Explore cache misses, search lag and repeated events. Then look at payment uncertainty.
- 01Choose a scenario to inspect its decisions.
A cache miss.
A clear source of truth.
Read the source, return the result and populate the cache with a bounded lifetime.
Interactive scenarios show system behaviour using sample data.
What I build with.
What I keep exploring.
Technologies I use in professional work and approaches I explore through personal projects.
