For scalability, robust community support, and future team building, I'd recommend considering Node.js. Its non-blocking, event-driven architecture makes it highly scalable, allowing your crowdfunding platform to handle a large number of pages efficiently. Additionally, Node.js has a vibrant and active community, providing ample resources for support and continued development.

If you're leaning towards Node.js, you might find this article on embedded system development insightful: https://www.cleveroad.com/blog/embedded-software-development/. While it focuses on embedded software, it touches on key principles relevant to web development, such as optimization techniques and real-time considerations. Ultimately, whichever option you choose, thorough research and careful consideration of your project's requirements will set you on the path to success. Best of luck with your crowdfunding platform!
