Why do developers contribute to open source projects, and how can these contributions be sustainable? The author of the text, Claire Knight, a senior software engineering manager at Netlify, shares her perspective on this topic. She believes that open source is essential for enabling web developers and advancing what's possible on the web. However, she also acknowledges the challenge of making open source sustainable when there are competing demands of time or investment. To address this issue, Claire and her team at Netlify are working to build an engineering group focused on ecosystem integrations and upstream contributions. Their goal is to foster innovation and collaboration across the Jamstack ecosystem, ensuring that frameworks have first-class support on Netlify, and providing a great developer experience. The team invites developers to join them in this journey by coming to work with Netlify's Ecosystem team.
