I built a full stack app in one day using AI tools - here is HOW and WHY

A few weeks ago I was applying for a job and noticed something that bothered me.

The moment I submitted my application it locked. Even though no recruiter had seen it yet. Even though I had a stronger resume ready the next day.
So I asked why. And then I built a solution.

What I built:

LiveApply is a prototype that keeps job applications editable until the hiring team actually starts reviewing. The window closes the moment the recruiter downloads all resumes simultaneously. Fair for every candidate.

The problem it solves:

Most ATS platforms lock applications on submission not on recruiter action. That is an arbitrary technical limitation that hurts candidates every single day. A fixed time window is still unfair. The window should close based on recruiter action not time.

Tech stack:

React + Tailwind CSS for the frontend
Supabase for database and file storage
Resend for transactional emails
Lovable AI for building the entire app
Deployed on Lovable

How I built it:

I used natural language prompts in Lovable AI to generate the entire application. No manual coding. I described what I wanted, Lovable built it and I iterated until it was right. The entire build took one day.
Three user perspectives

The prototype lets you test from three different views:

As a candidate you submit an application and get a unique link to update your resume, cover letter and portfolio for up to 2 minutes in the prototype. In the real product the window stays open until the recruiter starts reviewing.

As a recruiter you see all applications and a download button. In the real product clicking download closes all candidate windows simultaneously.
As an admin you have full read only visibility into all activity and metrics.

Try it yourself

Passcode for recruiter and admin: admin

The window is set to 2 minutes in the prototype so you experience the full flow quickly!

What is next
This is Version 1. Version 2 will integrate directly with existing ATS systems like Ashby and Greenhouse via their APIs so any company can plug LiveApply in without replacing their existing workflow.
Would love to hear your thoughts in the comments!
