REST & GraphQL APIs
Versioned, documented APIs with OpenAPI specs, validation at the boundary and error contracts clients can rely on.
Hire · Node.js & TypeScript
Hire Node.js developers who keep APIs boring — in the best way.
Dedicated backend engineers in TypeScript — REST and GraphQL APIs, multi-tenant SaaS, payment webhooks that reconcile and queues that don't drop jobs. Screened on systems they run in production.
Shortlist: 48 hours. Onboarding: 72 hours. Contracts: month-to-month.
What they do
What our Node.js developers own in your stack.
The unglamorous backbone: correct data, safe money movement and endpoints that stay up.
Multi-tenant SaaS backends
Tenant isolation, per-plan entitlements, subdomain routing and usage metering — the architecture we run in our own SaaS.
Auth, RBAC & sessions
JWT and OAuth flows, refresh rotation, role- and permission-based access and the audit logging that proves who did what.
Payments & webhooks
Razorpay and Stripe integrations with signature verification, idempotency keys and reconciliation — money state that always adds up.
Queues & background jobs
BullMQ on Redis for emails, exports, syncs and scheduled work — with retries, dead-letter handling and job dashboards.
PostgreSQL schema & migrations
Normalised schemas, safe migrations with Prisma or Drizzle, indexing strategy and query plans read before they bite.
Realtime systems
Socket.IO and WebSocket services for chat, presence, live status and notifications — scaled past a single process.
Third-party integrations
WhatsApp Business, SMS gateways, email providers, maps, KYC and accounting APIs — wrapped behind clean interfaces.
Performance & caching
Redis caching layers, N+1 elimination, connection pooling and load testing before launch days — not after.
Security hardening
Input validation, rate limiting, secret handling, dependency audits and OWASP-aligned reviews — before the pen test finds it.
Testing & CI
Unit and integration tests with Vitest or Jest, API contract tests and CI gates that block regressions from merging.
Docker & deployment
Containerised services, compose stacks, Nginx or Caddy fronting and zero-downtime deploys on VPS, AWS or DigitalOcean.

TypeScript-first, PostgreSQL-first — matched to whatever your services already run.

Engagement models
Three ways to hire a Node.js developer.
All models are month-to-month with a free replacement guarantee and senior code review included.
Flexible block
Pre-agreed block of hours. Best for API audits, performance work and integration sprints.
- Start from a 40-hour block
- Weekly hour reports
- Unused hours roll over one month
80 hrs/month
Half a developer, consistently. Best for keeping a production API healthy while shipping steady improvements.
- Fixed daily overlap window
- Same developer every day
- Upgrade to full-time anytime
Full-time dedicated
Most popular
160+ hrs/month
A backend engineer who owns your services — schema to deploy pipeline — inside your sprint cadence.
- Exclusive to your product
- Senior team-lead code review included
- Free replacement within 7 days
- 30 days notice to scale down
How it works
From brief to first deploy in four steps.
Backend candidates are screened on schema design and failure handling — the things that separate production engineers from tutorial graduates.
-
1
Brief
Your framework, database, hosting setup and the systems the developer will own.
-
2
Match
2–3 screened backend candidates within 48 hours, matched to your stack and domain.
-
3
Interview
You interview. You decide. Ask how they would make a webhook idempotent — good filter question.
-
4
Start
Onboarded within 72 hours — local environment up, staging access sorted, first PR in week one.
Why Smart Desizns
We run Node.js backends in production.
Multi-tenant SaaS, payment reconciliation, realtime messaging — our own products depend on Node.js services every day. That is the standard your developer is screened against.
Multi-tenant ERP
PharmOS
Node.js API powering a pharmacy ERP — licensing, tenant isolation, partner white-labelling and billing in production.
Realtime community opsHoodDesk
Backend for visitor approvals, notices, billing and helpdesk across societies — push fan-out and role-based access.
Dispatch platformRide-hailing platform
Trip dispatch, live location streams, fleet management and fare logic — the kind of stateful backend Node.js is built for.
FAQ
Hiring Node.js developers — common questions.
Express, NestJS or Fastify — which do your developers use?
All three, in TypeScript. If you have an existing service we match the framework you run; for greenfield APIs the developer will recommend based on team size and structure — NestJS for larger teams that want conventions, Express or Fastify for smaller, leaner services.
Can they take over a live API another team built?
Yes — it is the most common engagement. They start read-only: tracing routes, mapping the schema, checking auth and webhook handling, and adding missing observability. Only then do they start changing behaviour, behind tests.
How deep is their database expertise?
PostgreSQL first — schema design, migrations, indexing and query plans, plus Redis for caching and queues. Our own products run on PostgreSQL in production, so this is screened rigorously, not assumed from a CV keyword.
Do they handle deployment and DevOps too?
Day-to-day DevOps, yes: Docker, CI pipelines, environment config, reverse proxies and zero-downtime deploys on VPS or cloud. For dedicated infrastructure scope — Kubernetes, multi-region, compliance — we can add a DevOps engineer to the same engagement.
What does a dedicated Node.js developer cost?
Rates depend on seniority and engagement length — hourly, 80-hour part-time or full-time dedicated. Send a short brief and we quote in writing within a day, with no obligation until you have interviewed the candidates.
Need backend muscle without the hiring cycle?
Send your stack — framework, database, hosting — and the hours per week. You will have 2–3 screened Node.js CVs within 48 hours.
