Day with AI: 10 Bugs from the Gym, Website Redesign, and Server Infrastructure Migration.

First real gym test of the fitness app revealed 10 bugs. Plus personal site redesign, cron migration to VPS, and dashboard overhaul. 3 commits, 4 sessions, 3× deploy.

What I worked on

Friday. The day you find out whether what you built survives contact with reality.

What I did

Fitness app — 10 bugs from the first gym test

Took the app to the gym for the first time. And as it goes — on mobile in a real environment, everything that looked perfect on desktop fell apart. Ten bugs. State reset on refresh, horizontal scroll where it shouldn't be, buttons not responding, popups that won't close, and a meal section unusable on mobile. All fixed in one session. Plus I rebuilt the entire food section — new UX with categories, selection, and recipe details. Three deploys for this one.

Without AI? Two days of debugging. With AI? One afternoon.

Personal website — major redesign

Continuing the site overhaul. New visual style, SEO fixes, navigation, modals, logo, blog post automation, email capture form, and a pile of mobile fixes. Session tracked at 9 hours.

Infrastructure — cron migration from cloud to VPS

Moved all scheduled tasks from cloud hosting to a dedicated server. Reason: free tier limits and more control. Eight revenue crons, invoicing, monitoring — everything now runs on VPS via systemd. Cleaner setup, no vendor lock-in.

Dashboard — control center redesign

Overhauled the main system dashboard. New layout, better overview of running tasks, cron trigger times. Both visual and functional upgrade.

Time: AI vs without AI

Task	Without AI	With AI

Fitness app — 10 bugs + food UX	2 days	~3h
Personal site — redesign + SEO + mobile	3-4 days	~9h
Cron migration to VPS	1-2 days	~6.5h
Dashboard redesign	1 day	~2h
Total	~8 days	~20h

What I learned

No app is done until you test it where it's actually used — desktop preview lies
Ten bugs in one afternoon sounds crazy, but with AI it's routine — each bug takes minutes, not hours
Migrating infrastructure from a managed service to your own server is an investment — more work now, fewer limits later
Website redesign is a never-ending story, but tracked time helps keep perspective on how much time it actually eats
