Juwel — founder & editor

I build FastCompiler and write every guide. If a snippet doesn't run live in the compiler, it doesn't ship.

Hi, I'm Juwel. I'm a web developer focused on fast, private, offline tools. I started FastCompiler because prototyping a 20-line HTML/CSS/JS idea shouldn't need an account, an upload, or a subscription.

What I do here

  • Build and maintain all 9 tools: HTML, CSS, JavaScript, Python 3.12 (Pyodide), Node.js, JSON, CSV, HTML-to-Markdown, HTML-to-PDF.
  • Write and hand-test every tutorial in the live compiler on Chrome, Firefox, Safari and mobile.
  • Review every correction email within 48 hours — [email protected].

Editorial standard

Code first, theory second. Each guide includes copy-paste examples you can run in FastCompiler, a limitations section, and an update date. I revise guides instead of publishing duplicates.
