Hi, I'm Yoriiis β€” Front-end Architect at Prisma Media, focused on performance, design systems, user experience, and clean front-end architecture.

In addition to my daily work, I’ve been actively contributing to open source since 2012, building tools that reflect real-world needs with simplicity, scalability, and clear documentation. Some of my projects are used in production by developers and teams looking for lightweight, maintainable solutions.

πŸš€ Featured open source projects

  • Costro
    Build web applications with Components, Store, and Router β€” all under 3KB.

  • Figma CSS Variables
    Export Figma design tokens to CSS and automate deployment.

  • vLitejs
    Lightweight media player for HTML5 and YouTube videos, with custom skins and plugins.

  • ChunksWebpackPlugin
    Control how chunks and HTML files are generated in Webpack.

  • SvgChunkWebpackPlugin
    Optimize and bundle SVG sprites dynamically based on entrypoints.

  • ABTasty Debugger
    Browser extension to debug and inspect A/B tests from AB Tasty more easily.

🀝 Why Sponsor?

Maintaining open source takes time β€” from development to issue triage, testing, and support. Your sponsorship helps me:

  • Allocate dedicated time for updates, maintenance, and roadmap planning
  • Improve documentation, examples, and onboarding for new users
  • Offer support to developers using these tools in production
  • Experiment with new ideas and build tools that scale

Whether you're an individual developer or part of a team, your support makes a real difference.

Let's grow the ecosystem together β€” one clean, maintainable tool at a time.

Thank you for your support! πŸ™
