GitHub Freemium Promotion Specialist

I’m looking for someone to help turn my website content into a GitHub freemium promotion that can attract users and promote my product. The work should be similar to examples like GitHub/neetcode-gh/leetcode, where a free GitHub page or tool helps drive interest and engagement. I need support with planning the promotion, creating the GitHub content, and helping make it appealing to potential users. Please share relevant experience with GitHub-based promotions or similar growth-focused projects.
