# Hire a Node.js developer for your server > A Node.js developer builds the server side of your product: the logic, the data handling and the connections to other services. Hire one when your app needs more than a ready-made backend service can do. Canonical: https://erdibuilds.app/hire/nodejs Last updated: 2026-11-06 (November 6, 2026) ## What Node.js does Node.js lets developers run JavaScript on a server. The same language then covers the screen and the backend, which helps small teams and one-person projects. Servers written in Node.js are good at handling many requests at once, such as chat, live updates and busy APIs (Doors that let one program ask another program for data or actions.). Typical work: a [backend or API only](https://erdibuilds.app/build/backend-api) project, the server of a [mobile app](https://erdibuilds.app/build/mobile-app), webhooks that react to payments, scheduled jobs, file processing and the glue between several services. It pairs naturally with [React](https://erdibuilds.app/hire/react) and [Next.js](https://erdibuilds.app/hire/nextjs), and often with [Stripe](https://erdibuilds.app/hire/stripe) or [OpenAI](https://erdibuilds.app/hire/openai). ## Good questions for a Node.js developer - Do you write in TypeScript, and how do you keep the API documented? - Which framework do you pick and why? - How do you handle errors, logging and alerts when something fails at night? - How do you protect the API: logins, limits on requests, input checks? - Which database will you use, and how do you change it safely over time? - Where will it run, and how is a new version released? Ask for a short written overview of the API at the end of each phase. It saves time for any developer who touches the code later. ## Typical project phases A backend project can be planned around things you can test with a simple tool, even before the screens exist. Each milestone is funded before work starts and runs 1, 2, 3, 4, 6 or 8 weeks. The weeks in this example are for illustration, and developers set the length of each milestone in their proposal. **Example plan for a Node.js API** | | Work | What you receive | | --- | --- | --- | | For example, weeks 1 to 2 | Project setup, database, first endpoints, logins | A running test server and API documentation | | For example, weeks 3 to 4 | Main business logic and data rules | Test results for the core flows | | For example, weeks 5 to 6 | Connections to payments, email or other services | Each integration shown working in a test setup | | For example, weeks 7 to 8 | Monitoring, limits, deployment, handover | Server running under your own hosting account | Milestones are from 50 to 2,000 each in your project currency. Milestone length: 1, 2, 3, 4, 6 or 8 weeks. ## How matching works Developers list at most 6 technologies as Expert in (The ones they know best.) and others as Also works with (Technologies they are comfortable using.). Node.js is often listed alongside a frontend tool, so a project that needs both can find developers who cover both. Matching also looks at help type, project type, portfolio, budget fit and availability. The score runs from 0 to 100 with plain reasons, 40 is the minimum to apply, and 80 or more earns a Top match badge. Verified means an ErdiBuilds admin has reviewed the developer and approved the profile by hand. ## Frequently asked questions ### Node.js or Python for the backend? Both work well. Node.js is a natural fit when the team already uses JavaScript. [Python](https://erdibuilds.app/hire/python) is a strong choice for data work and AI features. The developer's experience matters more than the label. ### Do I need a Node.js server if I use Supabase? Not always. [Supabase](https://erdibuilds.app/hire/supabase) covers data and logins. A custom server helps for heavier logic, scheduled jobs or special integrations. ### Will it handle many users? A good design plans for growth in steps. Ask the developer which parts become the first bottleneck and how they would measure it. ### Can someone continue my existing Node.js code? Yes.
