CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this repo is

A single place that holds two related artifacts:

1. Personal website — Jekyll site published to GitHub Pages at https://blacksnail789521.github.io
2. Resume — LaTeX source + compiled PDF, served from the same site

Both surface the same identity, so personal info must stay in sync between them (see “Keeping info in sync” below).

Resume workflow

Resume sources live under resume/<YYYY.MM>/ (one folder per revision month, e.g. resume/2026.05/). .gitignore excludes everything in resume/ except resume/Ching Chang_Resume.pdf, which is the public URL the website links to (author.resume in _config.yml).

When updating the resume:

1. Edit the .tex (or .docx) in the current month’s folder. If a folder for this month doesn’t exist yet, create resume/<YYYY.MM>/ and start from the latest prior month’s source.
2. Compile to PDF in that same folder.
3. Copy the new PDF to resume/Ching Chang_Resume.pdf (repo root of the resume folder) — this is the only resume file tracked by git, and it’s what visitors download from the site.

Keeping info in sync

Any change to personal info (title, affiliation, location, education dates, links, email, etc.) must land in both:

• The latest resume under resume/<YYYY.MM>/ (and the copied resume/Ching Chang_Resume.pdf)
• The website — typically _config.yml (author: block) and _pages/about.md

After a sync edit, skim both to confirm no field drifted (e.g. job title in _config.yml matching the resume header).
