Andrew Nesbitt builds tools and open datasets to support, sustain, and secure critical digital infrastructure. He's been exploring the world of open source metadata for over a decade. First with libraries.io and now with ecosyste.ms, which tracks over 12 million packages, 287 million repos, 24.5 billion dependencies, and 1.9 million maintainers. What has Andrew learned from all this, who is using this open dataset, and how does he hope others can build on top of it all? Tune in to find out.
