Are you still managing team holidays with endless Excel sheets?
After jumping from one meeting to the next with barely a moment to breathe and code, I recently felt that familiar frustration:
I miss building things. I had ideas in my head, but no time to get my hands dirty and code.
Last weekend, inspired by Alexey's recent Substack on experimenting with AI tools, I finally took a break from the chaos and decided to create something again.
The Result
๐ A full-stack Holiday Planning App.
Not a simple static page โ a real app with structure and logic.
Under the hood:
โ Supabase Postgres Database
โ Secure Authentication (Admins invite users)
โ Different UI + permissions for each role
โ No more static spreadsheets for each year
โ Integrated school holidays and German national holiday
๐งช Tools I Tested
ChatGPT for better prompts
I uploaded a final design photo of the app and used ChatGPT to refine my prompts.
๐ Lovable
I entered the prompts to create a beautiful UI and design web. Much cleaner output than Cursor.
๐ป Cursor
Ran into repeated bugs โ I tried fixing them 6โ7 times โ but it struggled with the complexity.
๐ Google Antigravity (Gemini 3 Pro)
Solved the bug on the first attempt.
Great error explanations + step-by-step implementation help.
This was the strongest overall experience.
๐ง โจ My Takeaway
AI is an incredible creative accelerator if you actually use it.
Don't overthink โ just test, build, break things, and try again. I often hear people say they want to "develop themselves in AI," yet take no action.
For anyone curious about AI development:
Start experimenting. It's the fastest way to learn.
