Alexandro - Founder
PublishQ

Hi, I'm Alexandro 👋

I left my Software Engineer role at Amazon to build tools that solve real problems — the kind big companies ignore because they read spreadsheets instead of using their own products.

I was spending over an hour daily just scheduling 2 shorts across 3 platforms — logging in, reformatting, uploading one by one. That felt broken. So I built PublishQPublishQ. Now I create 4 shorts in 3 minutes and schedule them to 4 platforms in under 30 seconds.

PublishQ is bootstrapped. No investors, no vanity metrics. I build what actually helps you — because I use it every day myself.
