Node.js Development Company
Kawach Technology builds Node.js backends for real-time and integration-heavy software: REST and WebSocket APIs, order and event processing, and platforms that coordinate many connected clients such as point-of-sale systems, kitchen displays and mobile apps.

What Is Node.js and How We Use It
Node.js is a JavaScript runtime built for event-driven, non-blocking I/O. It handles many simultaneous connections efficiently, which makes it a good fit for APIs that mostly wait on databases and other services, and for real-time systems pushing updates to many clients at once.
We choose Node.js when real-time behaviour and integrations are the heart of the system, and when sharing TypeScript between frontend and backend reduces friction for the team. For the Bistro Nationale Group restaurant platform, a Node.js and PostgreSQL backend coordinates online ordering, POS integrations and kitchen display tablets.
What We Build With Node.js
REST & GraphQL APIs
Typed APIs serving web, mobile and partner clients.
Real-Time Systems
WebSocket-driven order tracking, notifications, presence and live dashboards.
Ordering & POS Integration
Order flows connected to point-of-sale systems and kitchen displays across many locations.
Integration Services
Middleware that connects payment, ERP, CRM and third-party APIs, with retries and monitoring.
Event & Job Processing
Queues and workers for webhooks, notifications and background processing.
SaaS Backends
Multi-tenant backends for JavaScript/TypeScript product teams.

Explore Custom Software DevelopmentWhen to Use Node.js, and When Not To
We recommend a technology because it fits your problem, not because it is the one we are selling.
Node.js is a good fit when
- Real-time updates to many connected clients are central (ordering, tracking, collaboration).
- The backend is mostly orchestration of other APIs and services.
- Your team works in TypeScript and wants one language across web, mobile and backend.
Consider alternatives when
- CPU-heavy processing or machine learning; use Python or a dedicated service.
- Admin-heavy business applications where Laravel or Django give you more out of the box.
- Teams without JavaScript experience maintaining the system long term.
How We Engineer Node.js Projects
Architecture
- TypeScript throughout, with schema validation at every API boundary.
- Framework chosen by scope: NestJS for larger structured backends, lighter frameworks for focused services.
- Background work moved to queues so request latency stays predictable.
- Idempotent handlers and retries for payment and third-party webhooks.
Security
- Dependency auditing and lockfiles to manage npm supply-chain risk.
- Input validation, rate limiting and secure headers on every public endpoint.
- PCI-aware payment handling via providers such as Stripe, so card data never touches your servers.
Scalability
- Stateless processes scaled horizontally, with Redis for shared state and pub/sub.
- Regional caching close to users, as used for Bistro Nationale's French locations.
- Connection pooling and read replicas for PostgreSQL under load.

AWS DevelopmentNode.js Development: Frequently Asked Questions
Node.js or Laravel for my backend?
Both are production-ready. We lean towards Node.js when real-time behaviour and API orchestration dominate, or when your team is TypeScript-first, and towards Laravel for admin-heavy business systems where its built-in features save time.
Is Node.js suitable for enterprise applications?
Yes, with discipline: TypeScript, structured frameworks such as NestJS, strict dependency management, automated tests and observability. Those practices matter more than the runtime.
Can Node.js handle real-time features?
Yes. Real-time updates over WebSockets are one of its strongest use cases, such as live order status pushed to many restaurant locations and devices.
Do you use TypeScript?
Yes, for new Node.js work. Shared types between the API and the React or React Native clients remove a whole class of integration bugs.
