zfish — Cross-Platform CLI Runtime (Rust)

High-performance terminal application framework with zero external runtime dependencies. Engineered for minimal binary size, fast cold-start, and ergonomic API surface across Linux, Windows, and macOS.

Performance & Design:

  • Static binaries < 1 MB
  • Zero-copy I/O via mmap syscalls
  • Work-stealing async scheduler
  • ANSI / true-color terminal support
  • Modular component system (prompts, tables, progress bars)

Hybrid K8s Mesh — Multi-Cloud Control Plane (AWS EKS ↔ Azure AKS)

Terraform-driven Infrastructure-as-Code topology with GitOps workflows and zero-trust Cilium networking. Built for resilient cross-cluster service routing and automated disaster recovery.

Scale & Reliability:

  • 40+ nodes across multi-cloud regions
  • < 30 s automated failover RTO
  • 15+ cross-region services in active-active mesh
  • Zero-trust network policies (Cilium + eBPF)

Home Lab Cluster — Bare-Metal vSphere Hypervisor

Production-parity environment for control-plane chaos engineering. Full observability pipeline: OpenTelemetry → Prometheus → Grafana.
