Holiday Planning App
by Xia He-Bleinagel
Xia He-Bleinagel built a full-stack holiday planning app on Django using AI tools: ChatGPT for prompts, Lovable for UI, Cursor for implementation, and Google Antigravity (Gemini) for debugging. Features Supabase auth, role-based access, and integrated school and German national holidays. No more static spreadsheets.
Xia He-Bleinagel (Head of Data & Cloud) built a comprehensive holiday planning app to replace endless Excel sheets for managing team holidays.
The app is built on Django and uses a mix of AI tools in the workflow:
- ChatGPT: to refine prompts (e.g. by uploading a design mock and improving instructions)
- Lovable: to create the UI and frontend (cleaner output than Cursor for design)
- Cursor: for implementation (ran into repeated bugs, fixed 6–7 times)
- Google Antigravity (Gemini 3 Pro): solved the remaining bug on the first attempt, with clear error explanations and step-by-step implementation help (strongest overall experience in her testing)
Features: Supabase Postgres, secure authentication with admin-invited users, different UI and permissions per role, and integrated school holidays and German national holidays. No more static spreadsheets per year.
