Most of us work through layers of abstractions every day — browsers, web servers, frameworks/languages, databases — but rarely have the time to dive into how things actually work.

With this newsletter, I'm sharing practical, deep dives into everything that goes into modern web apps — from programming language and framework internals to modern frontend tech to deployment.

Why bother understanding all this stuff? Can’t we just use AI tools to build our apps? Sure. We can. And then! we can use the time we saved to actually understand the system. Because I believe understanding is more fun — it’s fun to be competent. (And also...when we understand the system, we can review AI-generated code, debug faster, and feel more confident). I promise:

• Short posts (~750–1,000 words)

• Self-contained — all the value is in the email (no external links)

• One topic per post — with clear explanations and code snippets
