About J. Calloway

I'm a software engineer based in New York. I build developer tools, deploy production systems, and write about what I learn along the way.

What I Write About

Every article on this site comes from hands-on experience. When I compare two tools, I've actually used both. When I recommend something, it's because I'd use it myself.

• Developer tool comparisons — side-by-side breakdowns with real benchmarks
• Hosting and deployment — from serverless to self-hosted, what actually scales
• Security and privacy — tools and practices that protect your work
• AI and ML tooling — practical guides for developers integrating AI
• Databases — choosing the right data layer for your project

Why This Site Exists

Most "best of" lists are written by people who've never touched the tools they recommend. I wanted a site where every comparison is backed by real usage, real code, and real opinions.
