Your app works locally… but crashes after deployment? 😩

One of the most common mistakes I see is forgetting that local and production environments are different.

Before deploying, always check:

✅ Environment variables are correctly configured ✅ Production database credentials are set ✅ API URLs point to the right environment ✅ CORS settings allow your frontend ✅ Build errors are resolved ✅ Authentication works in production

My rule: Never assume that because it works on localhost, it's ready for production.

What’s the most frustrating deployment error you've faced? 👇

Shipped the 375ai website. This one was mostly a motion challenge.

375ai's whole pitch is real-time: thousands of sensors reading streets and shelves, turning the physical world into structured data. Hard to sell that with a static page. So most of my time went into the animation layer. The radar mark actually sweeps. Data blocks load in sequence, like a feed. Stats count up on scroll. Nothing in there is decoration, every movement maps to something the product does.

Then the unglamorous part: getting it built without wrecking performance. I spec'd every state and easing curve for the devs and we went back and forth until it held up on a mid-range phone, not just my monitor. A couple of animations I liked didn't survive that. Fine by me. A janky animation is worse than no animation.

Full case is on my profile. 🔥

Honest question for the web folks here: how do you spec motion in handoff? It's still the messiest part of my process.
