Hi, I'm

John Hankel.

CKA-certified Kubernetes engineer & AI developer

25 years in IT. I architect cloud migrations on OpenShift/EKS/GKE/AKS and develop AI-integrated tools that solve real problems. Currently focused on Kubernetes orchestration and AI-assisted engineering.

About Me

I’ve spent 25 years building and migrating enterprise infrastructure – from managing 60+ servers across international data centers to architecting multi-year cloud migrations on Red Hat OpenShift and AWS. I hold a CKA certification and have hands-on experience with managed Kubernetes across all three major clouds.

Outside of work, I develop AI-powered tools using Claude Code, LLM APIs, and local models. I’m particularly interested in the intersection of container orchestration and AI – building systems that are both well-architected and practically useful.

Technologies I work with:

Kubernetes (EKS, GKE, AKS, OpenShift)
Helm / Terraform
AWS / GCP / Azure
Docker
Python / Java
Claude Code / GitHub Copilot
Azure Entra ID / SAML / OAuth
Linux (RHEL, Ubuntu)
Bash / PowerShell
PostgreSQL / Oracle
CI/CD / GitLab / GitHub Actions
REST APIs
OpenText Documentum

Projects

Python Ollama Dear PyGui Git

AI Commit

AI-powered git commit message generator using local Ollama models. Includes a CLI for single-repo workflows and a Dear PyGui GUI monitor that auto-scans directories for repos, generates conventional commit messages from diffs, and supports accept/regenerate/edit flows with system tray integration.

Python Claude API Ollama Edge TTS Telegram Bot Async

AI Podcast Pipeline

Automated AI news aggregation system that scrapes multiple sources daily, generates podcast scripts via LLM (Claude API or local Ollama), synthesizes audio with neural TTS, and delivers to Telegram and Discord. Features async concurrent fetching, deduplication, and graceful fallback across generation modes.

Python FastAPI Scapy Docker iptables Raspberry Pi

NetGuard

Network access control system using ARP/NDP cache poisoning for agentless device management. Features a FastAPI backend with per-device scheduling, real-time bandwidth monitoring, Pi-hole DNS integration, and an auto-restoring safety mechanism. Dual-stack IPv4/IPv6 support.

TypeScript React Node.js Docker Helm Kubernetes

Container Image Compare

Full-stack web application for comparing Docker/OCI container images. Dual-pane interface for diffing metadata, environment variables, filesystems, and file contents between any two images. Includes Helm chart for Kubernetes deployment, Docker Registry API v2 integration, encrypted credential storage, and E2E testing with Puppeteer.

C# .NET 8 WPF XAML

Claude Usage Monitor

Real-time Windows desktop widget for monitoring Claude AI rate limits. Features animated utilization meters with color-coded thresholds, OAuth token integration, configurable polling, and single-file deployment via .NET 8 self-contained publish.

Python Claude Code LiteLLM Windows Terminal tmux

Agent Model Compare

Multi-model agent orchestrator that benchmarks AI models head-to-head by giving them identical tasks in isolated workspaces. Each model runs as a full interactive Claude Code session in its own terminal pane (Windows Terminal on Windows, tmux on Linux/macOS), with file-based progress tracking, automated test/launch validation, and side-by-side comparison reports. Supports Claude models directly and any LiteLLM-routed model.
