APIs other programs call
Routes with a clear error when the input is bad, and a limit on how big a request body can be.
Hire Node.js developers
Hire a Node.js developer who has kept an API responsive while other requests were waiting. Arca.ph cuts out the staffing-agency middleman. It is a private, invite-only network of engineers from around the world. Profiles are free to view. Your own AI agent, such as Grok, Claude, or ChatGPT, searches and sorts the network and builds a shortlist.
The role
A Node.js developer owns the API and the jobs behind it. One slow task on that process can make every other request wait, so that is part of the job.
Routes with a clear error when the input is bad, and a limit on how big a request body can be.
Node.js runs JavaScript one task at a time. They keep a long loop or a heavy parse from stalling the other requests.
A large upload or download moves in pieces, so the process does not hold the whole file in memory.
The same create request can arrive twice. The server still stores one record.
A failed request leaves a log that says why. When the process stops, it finishes work already in flight, then exits.
Every profile shows the hours they can work and the US time overlap, so a stuck API is a conversation during your day.

Stacks
These are skills developers list in their work history. You can compare them side by side.
What to look for
Look for:
You ask for an introduction, then you decide.
Cost
Success fee
An introduction is when the developer says yes.
Get startedHow hiring works
Sign up with your work email. We check that you're a real company, which keeps developers' details safe. Every profile shows pay, US time overlap, English and test scores, whether the developer is open to time tracking, and what makes that person different. Profiles are free to view.
Sign upBrowse profiles, or use your own AI agent, such as Grok, Claude, or ChatGPT, to search and sort them and build a shortlist. For Node.js, ask for a coding test with no AI allowed on a request handler, a 2-hour build project with AI allowed, or the Fire Drill (live pair-programming on a real-world problem), such as one slow call that makes every other request wait. Arca.ph returns the scores.
TestsTell us who you want to meet. We reach out. If they say yes, that's an introduction. On the marketplace, if you hire them, you pay one fee: 15% of first-year pay, once. There is a free replacement for 3 months. If Arca.ph introduces you to a developer you were already talking with, there is no fee.
If you hireInterviewing
Use these alongside your own technical interview. You make the hiring decision.
More questions are on Node.js interview questions.
Listen for the single thread, and how they move that work somewhere else.
Listen for one record, a key the caller sends, and a database rule that enforces it.
Listen for a stream or a size limit.
Listen for the error and a request id, and for passwords or tokens they do not log.
Teams also hire
APIs, data models, integrations, and the performance work behind them.
Hire backend developersOne engineer across UI, API, and database, for teams that need features shipped end to end.
Hire full-stack developersProduct screens in React and TypeScript, including the empty, loading, and error states.
Hire React developersCI/CD, infrastructure as code, observability, and cloud cost control.
Hire DevOps engineersPay is quoted per month, up to about $3,000 a month. On the marketplace, profiles are free to view. You can ask for proctored tests and recorded reference checks. If you hire someone Arca.ph introduced, you pay 15% of first-year pay, once. Published pay from named sources is on the developer rates page.
You can look at profiles right away. Profiles are free to view. When you want to meet someone, we make the introduction.
A coding test can ask for a request handler. The Fire Drill can be one slow call that stalls the other requests. When you want more proof, Arca.ph runs extra proctored tests and returns the scores. You can ask for a coding test with no AI allowed, a 2-hour build project with AI allowed, the Fire Drill (live pair-programming on a real-world problem), an English test, a thinking-skills test, and a typing test, plus recorded reference checks. A real person watches.
The profile shows the scope. Many Node.js developers own the route, the database writes, and the jobs that run after the response.
Every profile shows the hours a developer can work and the US time overlap, so you can pick someone whose day overlaps with yours.
Around the world. Every profile shows where the developer lives and the hours they can work.
If Arca.ph introduces you to a developer you were already talking with, there is no fee.
If you hire someone Arca.ph introduced and they are not the right fit, there is a free replacement within 3 months.
If you need help, Done-for-you is 35% of first-year pay, charged once on hire. Arca.ph runs the search and sends a shortlist. You hire and pay the talent directly. There is a 3-month free replacement.
