ERIC / ENGINEERING
Engineering stories about SDK architecture, AI developer tools, infrastructure, home automation and the systems I run.
Journal
How traffic reaches a small cluster from the internet and from the LAN, and why a single virtual IP is not the same as high availability.
Kubernetes Home Lab · Kubernetes, Ingress, Traefik, kube-vip, Networking
Moving a three-node control plane off Wi-Fi to eliminate etcd peer timeouts and restore a stable quorum.
Kubernetes Home Lab · Kubernetes, K3s, etcd, High Availability, Networking
What it takes to make an AI coding agent reliably integrate a platform — a workflow skill, a real codebase as a fixture, and a human-graded evaluation loop.
AI Developer Tools · AI, Developer Tools, Evals, Agents
A post-mortem of a cluster outage caused by a reverted VIP experiment, a stuck DaemonSet and a router ARP table with one MAC address for many IPs.

Project
A small self-hosted Kubernetes cluster built to run and learn from real workloads.
Selected work
Bringing an AI agent into an existing platform — MCP servers, reusable skills and evaluations as developer tooling.
Home automation — Zigbee, ESPHome and the slow path to a smart home that stays up.
A framework-agnostic TypeScript SDK platform — client core, multi-chain wallet connectivity, backend-driven configuration and public API evolution.
