Break One Dependency, Not The Whole Cluster
Scoped chaos rules are now in proxymock: pick traffic with a filter query, perturb it, and label every injected failure so it is never mistaken for a real one.

I built an API traffic classifier for business workflows
I pointed a classifier at 7,943 API calls to find business workflows. It worked, then showed where my assumptions about sessions and patterns fell apart.
Reliability Engineering in the AI Era
See why reliability engineering must span code, testing, telemetry, and incidents as AI agents erase the boundary between pre-production and production.
From Telemetry to Traffic
Compare eBPF, sidecars, telemetry agents, OpenTelemetry, APM, and proxies through an evolving ladder of production visibility.
Chaos Monkey Won't Find Your Bug
Infrastructure and application chaos break different layers and find different bugs. Netflix built two systems for a reason. Most enterprises buy just one.
Explain Non-CPU Latency With Prometheus + proxymock
Diagnose a p95 latency regression that CPU profiling cannot explain using Prometheus histograms, then prove the fix with identical proxymock replays.
Reproduce A Rare Retry Path With Loki + proxymock
Find the rare payload that sends a service down a retry path, correlate it to the recorded response, and prove the fix with proxymock replay.
Separate Application Latency From Network Failure With Hubble
Use Cilium Hubble flow evidence and proxymock replay to prove whether a Kubernetes timeout came from your code, a dependency, or a dropped packet.
Synthetic Monitoring Is Broken. Your Production Traffic Can Fix It.
Synthetic monitoring depends on scripts engineers maintain by hand. Capturing and replaying real production transactions turns customer behavior into tests.
