Only familiar with Python, occasionally dabbling in HTML, CSS, JS, but it’s a hassle and prone to errors.

Many folks want to build a simple backend, dashboard, or small tool but have to learn a ton of frontend first.

Divs, flex, responsive design… It’s exhausting and annoying. Even creating a table requires copying examples online, and customizing styles involves endless trial-and-error. Honestly, my head hurts when writing stylesheets, and I have to refresh multiple times after every CSS tweak—my back’s aching from it.
