Lab

Hands-on work from courses, homelab builds, and one-off experiments. Each directory stands alone. Where a directory came from a course, its name carries the source as a prefix: bootdev- marks Boot.dev coursework and codepath- marks CodePath coursework.

Topics covered

• Bash scripting: variables, conditionals, loops, functions, arrays, parameter expansion
• Shell and filesystem work: navigating nested trees, searching text, running and signaling scripts
• Dotfile management: shell config, editor setup, prompt customization
• Docker: multi-stage builds, health checks, unprivileged users, OCI labels, environment variables
• Docker Compose: multi-container applications with shared volumes
• Load balancing: reverse proxy and round-robin configuration with Caddy
• Kubernetes: deployments, services, configmaps, persistent volumes, horizontal pod autoscaling, Gateway API routing
• Observability: Grafana and Prometheus on Kubernetes via kube-prometheus-stack
• AWS: SSM Parameter Store, container images for ECS
• Go: local module imports, a test-first pass through the language and its concurrency tools, a REPL CLI with an HTTP client and a mutex-guarded cache, a net/http server, and TCP, UDP and HTTP request parsing from raw streams
• Python: small applications (containerized or run locally), a Pygame game, and a Streamlit app debugged with AI assistance
• AI agents: a Gemini tool-calling loop that reads, writes and runs files inside a working directory it cannot leave
• Git: branching, merge conflict resolution, rebasing, reverts, stashing, history rewriting
