Hire Node.js Developers
Node.js runs your JavaScript on a single thread with an event loop. That model is excellent for services that spend their time waiting on databases and other APIs, and unforgiving when one request does heavy computation and holds up all the others. Good Node.js developers design around that fact.
Ours work as part of your team. They commit to your repository, follow your branching rules and discuss the work with you in person on calls. PWTECH is the employer and provides equipment and continuity.
Node.js tasks worth handing over
Node.js is mostly used for the server behind a web or mobile app. The following six jobs account for the bulk of that work.
REST and GraphQL back ends
Services in Express, Fastify or NestJS with request validation, structured errors, authentication middleware and an OpenAPI or GraphQL schema that front-end developers can trust.
Real-time features
Chat, notifications, live dashboards and presence over WebSockets or Socket.IO. With more than one server instance, messages are relayed through Redis so that every connected client receives them.
Job queues
BullMQ or a cloud queue for email, image processing and imports. Jobs have attempt limits, delays between attempts, and a dead-letter list that is reviewed.
Moving to TypeScript
An existing JavaScript service converted file by file, with strictness raised in stages. Types are added at the boundaries first: request bodies, database rows and responses from external APIs.
Event loop and memory problems
Finding synchronous calls that block the loop, listeners that are never removed, caches that grow without limit. CPU-heavy work is moved to worker threads or a separate service.
Dependency and runtime upkeep
Upgrading to a current long-term support release of Node.js, clearing audit warnings, removing abandoned packages and dealing with the change from CommonJS to ES modules where libraries require it.
Runtime, frameworks and the rest of the toolchain
The npm registry offers a package for everything, which is both the strength and the hazard. We prefer a short list of well-maintained dependencies.

Choosing between junior, mid-level and senior Node.js developers
Almost every web developer has written some JavaScript. Server-side experience is a separate matter, and the levels here refer to that.
Junior
Adds routes, validation schemas and database calls by following existing examples. Understands promises and async functions. Likely to miss an unhandled rejection or a missing await unless a reviewer points it out.
Choose when: the codebase has linting and tests in place and a lead developer checks the work.
Mid-level
Builds complete modules with tests, handles errors and timeouts on every external call, and writes database migrations. Knows how streams work and uses them for large files instead of reading everything into memory.
Choose when: the product is established and there is a queue of features and fixes to get through.
Senior
Designs the service layout, decides where queues and caches belong, and plans for horizontal scaling. Diagnoses production issues from heap snapshots and event loop delay metrics. Sets the TypeScript and testing standards for the team.
Choose when: traffic is growing, the system is business-critical, or technical direction is missing.
What happens after you get in touch
You send the details
The Node.js version, framework, database and the task. Sharing package.json tells us the age and health of the dependencies straight away.
We introduce one engineer
You receive a named profile and hold the interview yourself. If you have doubts, we put forward a different developer.
A first task with clear limits
For instance one endpoint, one queue worker or one reproducible bug. You judge the result before agreeing to anything longer.
Ongoing work, reported weekly
Your tracker holds the tasks. A written summary arrives each week with what was released and what is stuck. One invoice is issued per month.

*160 hrs/month full-time. Rates are indicative for planning, in UAE dirhams (converted from our US-dollar rates at the fixed peg of 3.6725), before VAT where applicable, and depend on seniority, contract length and timezone overlap. Longer engagements and multi-role teams are discounted — ask.
Is this how you want to add Node.js capacity?
We are a good choice when
- Your back end is written in Node.js and development never really stops.
- Your front-end team uses React, Vue or Angular and needs a server-side counterpart.
- You want direct, daily contact with the developer.
- You are an agency looking for a Node.js engineer to work on client projects under your name.
Look elsewhere when
- The work is a one-off change of an hour or two.
- The developer has to sit with your team in person.
- Your main workload is heavy numerical processing. Another language will serve you better.
- You want a fixed fee but the feature list is still moving.
Node.js hiring questions
Express, Fastify or NestJS?
Express is the most widely known and has the most middleware. Fastify is faster and has schema validation built in. NestJS adds structure and dependency injection, which helps larger teams. For an existing service we stay with what is there.
Do you write TypeScript or plain JavaScript?
TypeScript by default for new code, because type errors are cheaper to find at build time than in production. We also maintain plain JavaScript services and can convert them gradually if you want that.
Our service slows down under load. Where do you look first?
At event loop delay, then at database queries, then at memory. One blocking call such as a synchronous file read or a large JSON parse can stall every request. Measurement comes before any change.
We are on an old Node.js release. Is that a risk?
Yes. Releases that have reached end of life receive no security patches. Even-numbered versions become long-term support releases, and we recommend moving to a current one. Native modules and old build tooling are the usual obstacles.
Is the Node.js code our property?
It does. The developer commits to your repository throughout. Ownership and confidentiality are covered in the agreement you sign at the start.
What cover is there if the developer is away or resigns?
We provide another engineer, subject to your approval. Notes and code already stored in your systems allow the newcomer to pick up the thread.
