What Node.js development services does Intelivita offer?

Intelivita provides Node.js development services for custom backend systems, full-stack applications, APIs, real-time applications, migrations, existing codebases and post-launch support.

Custom Node.js Development

Application Architecture • REST APIs • Microservices • Database Design

We build secure, business-aligned backend systems around your specific operational needs, designing architecture, database structures, RESTful APIs, and microservices for long-term scalability. You get full ownership of a backend built around your workflows, not one you have to adapt your business to fit. Our custom Node.js development gives you a backend designed around your processes and future growth.

Full-Stack Development

Node.js Backend • React • Angular • Vue.js

We build end-to-end solutions that combine a robust Node.js backend with modern frontend frameworks like React, Angular, or Vue. The result is a platform you fully own, with straightforward integration and a structure built around how your team actually works. Our Node.js full-stack development connects the frontend and backend into one scalable application.

Web Application Development

SaaS Platforms • Business Applications • SPAs • Server-Side Logic

We build dynamic, high-performance web applications, both single-page (SPAs) and multi-page (MPAs), designed around your business needs. This includes mobile app backend development, API integration, real-time features, and Node.js migration when an existing application needs it. Our Node.js web application development supports everything from customer-facing platforms to complex business applications.

Mobile App Backend Development

Mobile APIs • Authentication • Application Data • Real - Time Updates

We build the server-side backend that powers both iOS and Android applications, handling real-time data, secure APIs, and efficient database management through Node.js. That means your mobile apps stay responsive, push updates instantly, and scale as your user base grows. Our Node.js mobile app backend development provides the infrastructure your applications need to support growing users and data.

API Development & Integration

REST APIs • Third-Party APIs • System Integration • API Authentication

We build secure, reliable interfaces that connect your applications and services, so everything you run stays fully connected and ready for what you add next. Our Node.js API development and integration connects internal systems, third-party services, databases, and applications through reliable APIs,

Real-Time Application Development

WebSockets • Live Dashboards • Chat Systems • Real-Time Data

We build applications that need instant data updates, chat platforms, live dashboards, and collaboration tools using Node.js and WebSocket technology. The result is a responsive, real-time experience that keeps users engaged. Our Node.js real-time application development enables instant communication and data updates across connected users and systems.

Node.js Migration Services

Legacy Migration • Architecture Review • Business Logic • Code Modernisation

We modernise legacy systems by migrating them to Node.js, including apps originally built in PHP, .NET, or Ruby, preserving your existing business logic while improving speed, security, and maintainability. This means less technical debt and a platform built to last. Our Node.js migration services help modernise legacy applications without unnecessarily rebuilding existing business functionality.

Project Rescue & Recovery

Codebase Review • Architecture Fixes • Refactoring • Delivery Recovery

We take over stalled, broken, or underperforming Node.js projects from other vendors, assessing what's gone wrong, optimising the architecture, and getting delivery back on track, so you don't lose the investment you've already made. Our Node.js project rescue and recovery service helps stabilise existing applications and restore development progress.

Code Auditing & optimisation

Performance Audit • Security Review • Code Refactoring • Maintainability

We review existing Node.js codebases for security, performance, and maintainability, including "spaghetti code" cleanup, identifying bottlenecks, and refactoring against current best practices. You end up with an application that's cleaner, faster, and more secure. Our Node.js code auditing and optimisation identifies technical issues that can affect application performance, security, and long-term maintenance.

Node.js Consulting

Architecture Planning • Technology Selection • Migration Planning • Technical Feasibility

We provide strategic guidance on architecture, technology selection, and feasibility before development begins, so you can plan a project that's cost-effective and aligned with where your business is actually heading. Our Node.js consulting helps you make informed technical decisions before committing resources to development.

Node.js Support & Maintenance

Bug Fixes • Security Updates • Performance Work • Ongoing Development

We keep your application secure, current, and reliable after launch, with post-launch SLAs, bug fixing, security patching, and uptime monitoring so performance stays consistent without you having to chase it. Our Node.js support and maintenance keep your application stable, updated, and supported throughout its operational lifecycle.

Node.js Vs. Laravel: Which Is Better For My Business?

Node.js suits real-time applications built for growth, while Laravel development suits traditional, server-rendered PHP applications. We use Node.js for projects that need instant data updates, microservices, and non-blocking I/O.

Can You Take Over An Existing Codebase Developed By Another Agency?

Yes, we specialise in project rescue and code recovery for Node.js applications, reviewing stalled or underperforming projects, optimising the architecture, cleaning up existing code, and getting delivery back on track.

Is Node.js Suitable for Enterprise Applications?

Yes, we use enterprise-grade frameworks like NestJS and microservices architecture to handle large-scale, complex applications.

Do You Provide iOS App Development Alongside Node.js?

Yes, our iOS app development team builds Node.js backends that power iOS applications, giving you a fast, secure, and high-performing mobile experience.

Is Node.js Compatible With React Native Development?

Yes, we use Node.js to build APIs and backend services that connect efficiently with React Native development, enabling real-time features, notifications, and mobile functionality.

Can You Build a Backend for Hybrid App Development?

Yes, we build Node.js backends compatible with hybrid frameworks, so your hybrid app performs reliably across iOS and Android.

Do You Also Provide Android App Development?

Yes, our developers build APIs and microservices using Node.js to power Android app development giving you a high-performance, secure, user-friendly application.

Can Node.js Integrate With Python Development For AI?

Yes, we build Node.js backends that interact with Python-based AI models and services. Our Python development work enables data processing, analytics, and AI-driven functionality while keeping performance fast.

Is Node.js a backend technology?

Yes, Node.js is a backend (server-side) JavaScript runtime. It handles APIs, databases, and business logic and is commonly paired with a frontend framework like React, Angular, or Vue for the user-facing side of the application.

Is Node.js still in demand?

Yes, Node.js remains one of the most widely used backend technologies for real-time applications, APIs, and microservices architecture, with strong ongoing support from the OpenJS Foundation and a huge enterprise adoption base, including companies like Netflix, PayPal, and LinkedIn.

Is Node.js faster than Python?

Yes, Node.js is typically faster because of its non-blocking, event-driven architecture. Python tends to perform better for CPU-heavy tasks like data processing and machine learning, which is why we often pair the two. A Node.js backend handles requests, with Python as the AI or data-processing layer.
