Yangjeep Engineering Notes

Linux and carrier-grade systems roots, now spanning platform infrastructure, reliability, data systems, and engineering organizations.

— architecture, operations, economics, and ownership

# 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.
▸ Platform engineering & economics — reliability, observability, cloud cost, release infrastructure, and the architecture trade-offs behind operating systems well.
