Systems courses, open-source infrastructure, and self-hosting notes
Profile
Pusen Yi
Developer focused on systems, infrastructure, and self-hosted tools
I write about operating systems, networking, developer tooling, and small self-hosted infrastructure. This site is where the writing, projects, and personal services are collected.
SvelteKit, TypeScript, Linux, containers, PostgreSQL, OIDC
Personal code hosting, CI/CD, identity, and federated communication
Work I care about
- Building small, maintainable services instead of depending on a single hosted platform.
- Keeping developer workflows portable across local machines, containers, and self-hosted systems.
- Writing technical notes that connect implementation details with long-term maintenance tradeoffs.
Infrastructure interests
- Forgejo and Crow CI for code hosting and build pipelines.
- Rauthy and OIDC for a shared identity layer across personal services.
- Matrix and ActivityPub-style services for communication that is not tied to one vendor.
