The focus of my open source work is the development and maintenance of React-Virtuoso, a library solving the hard problem of displaying large lists with variably sized items.

While suitable and convenient for simple lists, React Virtuoso shines (and has no alternative) for UI like data feeds, chats, and timelines. I chose to solve this niche problem because it has previously beaten me (and wasted months of effort) during my programmer life. I am releasing it publicly so that you don't bang your head against the wall reimplementing binary searches and reactive programming patterns.

Apart from being the avatar next to the response to your GitHub issue, I am also an actual human being just like you - paying bills, raising children, and feeding a family. Your sponsorship will let me help you more. If Virtuoso is playing an important role in your project, please consider sponsoring it personally. If your company is making money with an offering that bundles Virtuoso, ask them to sponsor the project.
