Smarteeva Risk Management
Summary
Evermind™ — a fast-growing European SaaS company — was preparing a full platform redesign: new UI, new navigation, new onboarding, and a rebuilt permissions system. But the engineering team was stuck.Their codebase had accumulated years of async drift — un-awaited promises, deeply nested chains, race-condition hazards, and logic that worked “most of the time… except when it didn’t.”
What you will learn
Smarteeva started with a full async map of the codebase — parsing every function, promise chain, and cross-module dependency.The Editor flagged unstable flows, Debug surfaced non-awaited calls and silent failures, and Review mapped where side effects were leaking across boundaries.Patterns emerged quickly:
- 47% of async handlers returned before their internal operations finished
- Several “harmless” utility functions introduced hidden parallel execution
- Error propagation was inconsistent across 6 core services
- One legacy module triggered three parallel writes without guaranteeing order
