Yangjeep Engineering Notes

Linux and carrier-grade infrastructure roots — now stretched across customers, AI, and the business problems that don't respect org charts.

# what I'm actually building and running, updated as it changes

▸ LeaseLab — property management, built event-driven because I got curious whether the domain actually needed it. Still finding out. leaselab.io
▸ Agentic development workflows — using Claude Code and similar tools for real engineering work, not demos, and writing up what actually holds up.
▸ Homelab & observability — infrastructure experiments that mirror the platform problems I deal with at work, at a scale I can break safely.
▸ AI-assisted engineering systems — where agentic AI actually earns a place in a support/engineering org, and where it doesn't yet.
