Need a next.js developer for backend functionality

I am looking for an experienced developer to fix issues with my blog platform, https://codewithlogs.com/. Specifically, I need help resolving problems with scheduled blog posts not publishing automatically and issues related to uploading blog content and images. The ideal candidate should have experience with Next.js, MongoDB, and debugging web applications. The goal is to ensure that blog scheduling works reliably, uploads function correctly, and the overall system runs smoothly without affecting existing content. If you have experience with similar projects, please share your relevant work and approach.
