OpsPilot is a project I'm building to explore the intersection of backend engineering, DevOps, cloud infrastructure, and AI agents.
The goal is to help engineering teams investigate production incidents faster.
Alerts become incidents, an AI-assisted workflow investigates relevant logs, metrics, and system state, and suggested remediation remains under human approval before execution.
