32 years in the dev trenches. Here I write what I learned, what I broke, and what nobody tells you in the tutorials.

navigator.clipboard.writeText looks trivial until your app silently breaks in production with zero visible error. I found 4 cases the docs never mention: insecure context, lost focus, revoked permissions on iOS, and React timing. Here are the real patterns with copyable code.
I scored 98/100 on Lighthouse and axe on juanchi.dev. Then I asked someone who actually uses a screen reader to try it. What happened next embarrassed me. A perfect score and a real experience are two completely different things.
There's a deeply embedded belief in the dev community about AI in production that's just wrong: that you need an API, a server, and a credit card to add intelligence to your app. I ran it in the browser. No cloud. No billing. And now I can't stop thinking about what this means.
Brutal diagnosis, concrete changes, and real metrics. Here's how I took a Next.js app from embarrassingly slow to 300ms FCP — no magic, no excuses, just actual work.
An honest postmortem of building my portfolio with the freshest stack of 2025. Spoiler: almost everything broke. I rebuilt it anyway. Here's why it was worth every hit.
I migrated three production projects from Pages Router to App Router and broke everything twice before I truly understood how it works. Server Components, streaming, cache, nested layouts — here's everything nobody tells you.
