I write technical notes on web development, AI systems, and software engineering.
This site documents what I build, what I learn, and how different systems work in practice. The focus is practical implementation: setup decisions, debugging paths, code examples, architecture trade-offs, and lessons learned from real build work.

Author of Web101 by Han. I publish implementation notes, build logs, and technical explanations for builders who want practical context instead of generic summaries.
Writing method
How I write technical notes.
The goal is to make each article useful as a small technical record: what problem showed up, what I tried, what worked, and what I would watch for next time.
Start with a specific implementation problem or system behavior.
Document the setup, constraints, code path, and trade-offs.
Connect each article to related technical notes and topic pages.
Keep explanations practical enough that another builder can reproduce the steps.
Current archive
Four topic paths, 11 published notes.
Web Development
Frontend architecture, deployment, hosting, performance, and implementation guides.
AI Systems
RAG, LLM workflows, vector search, embeddings, and applied machine learning systems.
Technical Notes
Build logs, debugging notes, algorithms, and practical implementation details.
Case Studies
Implementation case studies that document the problem, setup, trade-offs, and result.
