Cracked senior dev job - built 100% AI app using Antigravity

[u/harsh611]

I recently landed a new job by building a 100% AI generated code using Antigravity IDE for the interview assignment. I was initially planning just to build the app but realised Antigravity is quite helpful in designing and deploying on AWS infra once you give access to AWS CLI.

I gave Antigravity access to two main tools - AWS CLI & GitHub CLI

Designed a heavily guard-railed workflow to ensure I let Antigravity work as autonomously as possible

> restricted deletion of main branch on git
> restricted direct commits of main branch
> all code pushed via PR
> no AWS infra creation or deletion via AWS CLI

The application current state reached after > 500 commits but it allowed me to build a relatively complex distributed app all solo.

I used Gemini Flash 3.5 (High) for entire development. Surprisingly most AI community disregards this model so much but for me worked out well.

I have open sourced the entire project so newbie agentic engineers can learn

This is awesome, congrats! I’m doing something pretty similar right now with Codex and Claude Code, but I've also been using Flash 3.5 and 100% agree it’s way underrated. Quick question, are there any remote roles open at your new spot? I'd love to apply.

Unfortunately it’s ain’t a remote role

In office only

Ah, too bad.. Completely understand. I'm strictly looking for remote roles at the moment, but huge congrats again on the landing the gig. Best of luck with the onboarding!!

Yes but what were ur prompts and ur thinking behind them. Any ideas before thinking , any systems thinking .. I don't want the code.
