Node.js Guru for Service API Development

I'm working on a Service API project and I need an expert in Node.js programming to assist me. Specifically, I need help with building the server-side logic. Ideal freelancers should have solid experience in Node.js and server-side logic creation, along with strong problem-solving skills. Your role would involve not just coding, but also answering any questions I might have about the process. Critical thinking and the ability to effectively communicate complex technical information are essential for this project.
