■
DNS & Security
- ▸ CoreDNS plugin development (policy engines, exfil detection)
- ▸ DNS-based security controls at infrastructure layer
- ▸ Query pattern analysis for threat detection
■
Performance Engineering
- ▸ pprof profiling: CPU, memory, goroutine analysis
- ▸ Benchmarking: dnsperf, ab, wrk for throughput testing
- ▸ Optimization: reducing latency, improving resource efficiency
■
Kubernetes Ops
- ▸ Custom operators (Kubebuilder/Operator SDK)
- ▸ Helm charts for repeatable deployments
- ▸ Observability: Prometheus/Grafana integration
■
LLMOps (Planned Sprint)
- ▸ Inference optimization: vLLM, caching strategies
- ▸ Cost tracking: token usage → monthly cost projections
- ▸ Latency monitoring: p50/p95/p99 metrics

- ▸ DNS Security Plugin: Built inline policy engine for CoreDNS enabling zone-level access control without upstream firewall changes.
- ▸ Performance Optimization: Reduced query latency by 40% through pprof-guided optimization and connection pooling improvements.
- ▸ Observability Pipeline: Designed Prometheus + Grafana stack with custom exporters for real-time DNS metrics and alerting.
