From Blind Spots to Merged PRs: Continuous Agentic Performance Optimization
summary
Claims a production system that runs weekly agentic analyses and surfaces verified fixes that turn into merged PRs, not prototypes; shows P90 latency improvements after deployment and fixes N+1 queries and missing indexes within the first week. Describes concrete stack choices: GitHub agent workflows and Actions, Cloud Code, HUD prod-to-code mapping, ClickHouse queries and skills, runtime evidence capture (MCP) and automated test reruns to verify impact. Reports numbers: hot endpoints invoked ~7,000 times a week and a scoring system for high-ROI, low-risk fixes.
