A decade of keeping large Linux fleets honest.

The safety layer around fleet-wide configuration and software rollouts, canary stages, blast-radius controls, automated rollback triggers, and moratorium enforcement during freeze windows. The point was to make safe deployment the default path, not something that required heroics from the on-call.

Progressive rollout gates, automated health-check integration, fast detection of bad config, and post-rollout validation that runs without human intervention.

Built and operated observability pipelines across OpenTelemetry, Grafana, Splunk, and KQL-based investigation tooling. Defined SLOs and error budgets for critical services, shifting the reliability conversation from subjective “is it healthy” to measured trade-off decisions.

Ran incident response for fleet-scale Linux operations, on-call triage, postmortem culture, and turning every meaningful incident into a systemic improvement. Particular focus on postmortems that produce durable defaults instead of paperwork.

Led infrastructure modernization to remove node-local state from services, enabling migration toward containerized and Kubernetes-based platforms. Designed self-rehydrating service patterns and recovery-oriented defaults so services could restart on any available host without data loss.

Modernization without state decoupling is just re-platforming a problem. The hard work is designing for recovery from the start, not bolting on reliability after the migration is done.

Experimental tooling that applies LLM-assisted analysis to configuration dependency graphs, helping engineers understand the downstream impact of a proposed config change before it ships. The goal is operational decision support, not automation for its own sake.

Practical applications include configuration conflict detection, rollout impact previews, and debugging assistance that reasons across the full configuration graph rather than treating changes in isolation.
