Another leftover from my app’s original brutalist design is gone. I’m still not sure why I chose that direction. It looked striking at first, but the more I used it, the harder it was to read—and the less I wanted to look at it.

@omaruecos Basically, no more boring forms. You just chat with it, like you would with a career coach.

Building Auto Apply for Profilis.

Pick a job. Review the prepared documents and answers. Approve what gets sent.

If something needs your input, it pauses.

Still testing, but the goal is simple: spend less time filling forms without losing control of your applications.

I called my Dock a grayscale graveyard. So I built Icon Spice 🌶️ Give your Mac icons some personality. Preview, apply, restore. Runs locally, with optional AI customization. Open source. Early build.

@rpa_dake Everything is half finished I have to say but I am getting there slowly :)

[Luka Korolija @corolladev]

My feature graveyard used to fit on one screen: a few half-built ideas.

Now Profilis has a job board, Lumerec has three shelved updates, and I have a folder of code called "personal" I'm afraid to open.

@vsachar @angelacollinshq It definitely does, we get way more done for less time

@Mojsilovic Anthropic is still the champion at delivering bad news. Everyone gets mad when they do.

@TheXSami Hi Sami, I think just the sheer volume of new apps being built doing the same. The competition has never been higher and you really have to fight to get your product seen and used

@itskamrankhan Hi Kamran, nice to meet you, let’s connect!

[Luka Korolija @corolladev]

Spending less time on job boards is a huge part of reducing the mental load of a job search. If you're manually matching every listing to your resume, you're burning energy that should go toward actually getting the job.

[Luka Korolija @corolladev]

Curious how other builders structure their agent loops.

I split implementation and review into separate sessions so the reviewer isn't biased by its own code. Anyone else running this overnight?

[Luka Korolija @corolladev]

@annasoreskin Thanks Anna, what are you building?
