Most outages in distributed systems don’t happen instantly. They start with small signals like latency drift, retry amplification, and error propagation across services.
I built FAULTLINE, a prototype system that detects these early signals and identifies when a cascading failure might be forming — before the outage actually occurs.
This project explores how combining signal convergence with AI-driven insights can shift monitoring from reactive alerts to predictive reliability.
