Become a sponsor to Leandro Pereira

Hello! I'm Leandro Pereira

I’ve been part of the amazing Elixir community for a decade — sharing, building, contributing, and maintaining tools used by developers, teams, and companies around the world.

All my projects together are on track to hit 1 million downloads soon. Thank you all for the trust and support!

Why sponsor?

Your contribution helps me keep pushing the Elixir ecosystem forward (and a little Rust too!). There’s a lot I want to improve, refine, and build — and the backlog is long! Sponsorship gives me the time and focus to keep these tools evolving.

Projects

  • MDEx - Fast and extensible Markdown for Elixir. CommonMark-compliant; HTML, HEEx, JSON, XML, Quill Delta; Plugins. Built on comrak, ammonia, and autumnus.
  • MDEx Plugins - GitHub Flavored Markdown, Mermaid, KaTeX.
  • Autumnus - Tree-sitter–powered syntax highlighter with Neovim-inspired themes. Beautiful, accurate highlighting for 50+ languages and 100+ themes.
  • Autumn - Elixir port of Autumnus, bringing beautiful syntax highlighting to the BEAM.
  • req_embed - Req plugin to fetch oEmbed resources + a Phoenix component for embedding rich external content.
  • err - A tiny library that makes working with {:ok, value} and {:error, reason} tuples more ergonomic and expressive.

Thanks for checking out my work — and for supporting open-source in any form. Every star, issue, PR, and sponsorship helps keep these projects alive and improving. Even a small contribution makes a big difference!

If I hit 10 monthly sponsors, I can justify spending even more late nights improving MDEx, polishing syntax highlighting, building new plugins, and experimenting with new ideas 😄
