About this site
I’m Hung-Chih Hsueh, a frontend and full-stack engineer based in Taipei. hch-log is where I record technical learning and implementation: how a problem happens, why an approach works, and where it stops being useful.
What you can find here
The notes cover the Web platform, Cloudflare deployments, PostgreSQL, AI tool workflows, and TypeScript programming problems. Start with a featured problem on the home page or follow a topic guide.
Sources and verification
Course notes identify their source. Technical explanations link to official documentation and distinguish references, reasoning, and demonstrations. Reproducible examples describe their data, execution steps, and limitations. Measurements apply to the stated environment, not automatically to production.
I may use AI to assist with writing and code checks; I remain responsible for reviewing references, technical claims, and published content. Completing a note does not establish independent mastery. Historical records do not automatically become current advice when tools change.
