Hire senior Node.js developers
Back-end developers for the APIs behind your web and mobile products: clean contracts, safe database changes, background jobs that can be retried, and logs that tell you what went wrong.
Short answer
elitics provides senior Node.js developers from Prishtina who build APIs, real-time features and integrations in TypeScript with NestJS, GraphQL or REST, PostgreSQL, Prisma and Redis, including queues, webhooks and zero-downtime migrations. You interview the developers, they start about 48 hours after you approve their profiles, and team extension costs €45–65 an hour.

What our Node.js developers build
- APIs for web and mobile
- REST or GraphQL APIs with authentication, roles, pagination and versioning that clients can rely on.
- Real-time features
- Chat, notifications and live dashboards over WebSockets, with presence and reconnection handled.
- Integrations and webhooks
- Payment providers, CRMs and ERPs connected through webhooks and scheduled syncs that survive outages on either side.
- Background processing
- Queues for emails, imports, reports and AI jobs, with retries, dead-letter handling and visibility into what is stuck.
What a senior Node.js developer should own
Node.js is quick to start with. These are the habits that keep a back end reliable at scale.
- The event loop
- CPU-heavy work kept out of request handlers, in worker threads or queues, and no blocking calls on hot paths.
- Safe retries
- Idempotency keys and stored event IDs, so a webhook or job that runs twice does not charge, email or ship twice.
- Database discipline
- Indexes based on real query plans, no N+1 queries, and schema changes deployed in expand-and-contract steps.
- Observability
- Structured logs with request IDs, metrics and traces, so an error report leads straight to the failing request.
Questions to ask a Node.js developer
These questions show whether a candidate has run Node.js in production.
- 01
What happens if you resize images inside a request handler?
The event loop blocks and every other request waits. Move the work to a worker thread or a queue, and return a job ID.
- 02
How do you make a webhook handler safe to call twice?
Verify the signature, store the provider’s event ID, skip events already processed, and return success quickly before slow work.
- 03
An endpoint got slow as data grew. How do you find out why?
Look at the query log and the plan: N+1 queries from the ORM, missing indexes, or large payloads without pagination.
- 04
How do you rename a column without downtime?
Expand and contract: add the new column, write to both, backfill, switch reads, then drop the old column in a later release.
- 05
REST or GraphQL for our product?
Depends on the clients. REST for simple, cacheable resources and public APIs; GraphQL when several clients need different shapes of the same data.
How hiring an engineer works
- 01
Tell us the role
Stack, seniority, start date and the hours you need to share. A call with our engineering lead takes 30 minutes.
- 02
Review profiles
You receive engineer profiles matched to your stack and interview the ones you choose.
- 03
Start in about 48 hours
NDA and IP assignment are signed, and the engineers are set up in your repositories and tools.
- 04
Two-week trial
If you are not satisfied, you do not pay for those two weeks. An engineer who is not the right fit is replaced at no extra cost.
Typical set-ups
- One back-end developer
- Joins your team to take on APIs and integrations while your developers focus on the front end.
- Platform pair
- Two developers who own a service, its database and its on-call runbook.
- Full-stack squad
- Node.js and Next.js developers with QA for a new product or a rebuild.

Common questions
Do you also work with other back-end languages?
Yes. Node.js with TypeScript is our most common back end, and we have specialists for Rust, Elixir and .NET when your systems use them.
Can your developers take over an existing API?
Yes. They start by reading the code, adding tests around the riskiest parts and setting up logging, then take over features and fixes.
Do they handle hosting and deployment?
They deploy through your CI/CD pipeline on AWS, Google Cloud or Vercel. For infrastructure work, our DevOps engineers can join the team.
How are hours tracked and billed?
Team extension is billed monthly for time worked, with transparent time tracking and month-to-month terms.
