About

Gerald Chen

I’m a frontend engineer who has been shipping production code since 2015, with experience across financial data platforms, enterprise SaaS products, and AI tooling. My long-term interests are frontend engineering, performance optimization, and the intersection of AI and developer workflows. This blog is where I organize my day-to-day thinking, technical learning, and hands-on experience.

Tech Stack

• Frontend: JavaScript / TypeScript, React, Vue, Astro, Web Components
• Engineering: Webpack, Vite, Bun, ESLint, Prettier, Monorepo, CI/CD
• Backend: Node.js, Go, Python, PostgreSQL, Redis
• AI & Agents: Claude Code, Cursor, MCP protocol, LangChain, LlamaIndex
• Other: performance optimization, PWA, web security, observability, Docker, Linux operations

About This Blog

This blog was originally built in 2015 with React + Redux + Webpack — back when React had no Hooks and the state-management ecosystem was just getting started. In 2026 I migrated the whole site to Astro, built on a customized version of the AstroPaper theme.

Why Astro:

• Static generation + islands architecture: a blog is a natural fit for SSG, and Astro’s islands keep the site fast while still allowing local interactivity
• Fast builds: compared with my old Webpack setup, both the dev experience and build speed are far better
• MDX support: React components can be embedded directly in Markdown, which makes interactive content much easier to write

What I write about:

• Hands-on reviews of AI tools and agent frameworks (Claude Code, Cursor, Copilot, MCP tooling, and more)
• Concrete case studies in frontend engineering and performance optimization
• Browser internals, JavaScript engine mechanics, and the evolution of web standards
• Software supply-chain security, dependency management, and code review
• Occasional reflections on work and career growth

Every article is grounded in real working experience and first-hand research — no hand-waving, no recycled second-hand summaries. If you spot a mistake or something that could be improved, I’d genuinely appreciate hearing about it through the channels below.
