I made an app for pulling data for UK postcodes from the postcodes.io API. https://postcode-explorer.mikehiggins.me.uk/
The process was a little convoluted.
1/ Used ChatGPT Agent to digest the API docs and come up with an HTML/CSS/JS MVP which I tested and refined.
2/ Copy pasted the code into Lovable along with a style guide to work on the interface.
3/ Committed the Lovable app to Github and synched the repo with a host (Netlify) and my IDE (Antigravity).
4/ Debugged and worked on the code in Antigravity with Gemini 3.
5/ Created the background animation in Claude and then integrated it. 
6/ Changed API handling from the front end (CORS) to a backend serverless Netlify function to make everything more robust.
The  majority of work was in Antigravity, which, because of Gemini 3, is jaw-droppingly good.
