How I Built This Blog: The Modern Serverless Tech Stack

When I decided to revamp my blog, I wanted a setup that was fast, cost-effective, and easy to maintain. But more importantly, I wanted to experiment with a fully AI-assisted development workflow.

This blog isn’t just hosted on the cloud—it is maintained and evolved by an AI Agent.

The Core Stack

I chose a static site architecture for its speed and security.

• Engine: Hexo, a fast and simple static site generator based on Node.js.
• Theme: Icarus, giving it that clean, professional look.
• Storage: AWS S3 buckets to host the static HTML/CSS/JS files.
• Delivery: AWS CloudFront (CDN) to serve content globally with low latency and SSL.
• DNS: Amazon Route53 for domain management.

This “Serverless” setup costs practically nothing to run and scales infinitely.

The AI-First Workflow

The most interesting part isn’t the stack itself, but how it represents a new way of working. I use Google’s Antigravity, an advanced AI coding agent, to drive the development and maintenance.

Instead of manually editing config files or searching for plugins, I simply conversed with the agent:

“Implement a Sitemap and RSS feed.”
“Fix the domain verification issue.”
“Generate cover images for all my posts.”

The agent analyzed my project structure, installed the necessary plugins (hexo-generator-sitemap, hexo-generator-feed), and updated the _config.yml automatically.

AI-Generated Art

You might have noticed that every post on this blog has a unique cover image. These weren’t found on stock photo sites—they were generated on the fly by the agent using Google’s Gemini 3 Pro. I simply asked it to “scan my posts and generate relevant images,” and it handled the rest.

SEO & Discovery

To ensure this content reaches you, we implemented standard best practices:

1. Sitemap: Automatically generated at /sitemap.xml for search engines.
2. RSS Feed: Available at /atom.xml (link in the sidebar!) for subscribers.
3. Performance: Minified assets and edge caching. We enabled hexo-all-minifier which reduced the total site build size from 20MB to 10MB (a 50% reduction!) primarily through intelligent image optimization. Then we further optimized by converting heavy images to WebP!

Conclusion

Building this blog was a testament to how AI agents are changing software development. We moved from concept to a fully polished, SEO-optimized, and visually rich site in a fraction of the time it would normally take.

Stay tuned for more updates on AI, Cloud, and the future of coding.
