[Xiang13-gif]

What changed

• Rebuilt the public portfolio as a recruiter-first Banking Business Analyst site
• Consolidated the story into three complementary case studies led by CreditFlow
• Added evidence-led BA content covering requirements, business rules, UAT, change impact, traceability, risk, controls, and release decisions
• Added an anonymized experience narrative and a sanitized public resume PDF
• Added responsive light/dark UI, accessibility, SEO metadata, structured data, static export, and GitHub Pages deployment
• Replaced the legacy single-page site with maintainable typed content and a professional repository README

Why

The previous site emphasized visual presentation and feature quantity. This version prioritizes recruiter clarity, credible evidence, Banking BA positioning, confidentiality boundaries, and maintainability.
