@GuptaSayujya Happy Birthday

[Sayujya Gupta @GuptaSayujya]

Everyday 1000s of job posts are posted on X,

Yet you can't find any, cause X search sucks.

So, I built an app that finds out all the recent jobs for you.

I could easily charge $40/month for this

But today I'm giving it away for FREE
(cause it's my birthday)

How to get it?

- Follow me
- Repost this post
- Comment "Happy birthday"

And I'll share the link with you.

This is how it works:
