Deep dives, investigations, fun. Complex topics, easy read.
No PhD required.
Three investigations hot off the press.
How does AI actually remember things between messages, and why does it forget halfway through? I ran a few experiments on Claude Sonnet and GPT-5 and wrote down what I saw.
Can AI actually debug complex React/Next.js issues? I tested it on three real bugs, investigated the root cause myself and wrote down the results.
Can React Server Actions replace fetch for client-side data fetching? Let's investigate and find out.
Deep dives, investigations, performance patterns and techniques.
If you think you know everything about React, this book might surprise you 😉. It's the guide to React you wish you'd had when you were learning it.
A Frontend Developer's Guide to Profile and Optimize React Web Apps.
Want to make your React apps even faster? Time to learn Core Web Vitals, performance profiling, server vs client rendering, etc. Stuff that actually moves the needle.

A practical guide to analyzing and reducing JavaScript bundle size. Learn bundle analysis, fix tree-shaking issues, remove duplicate libraries, and otherwise optimize your React app's JavaScript size.
How AI actually works, and how to make it behave beyond vibe-coding.
