Overview

Our approach

We build enterprise backend systems with Node.js — REST APIs, real-time applications, and event-driven microservices architected for concurrency, scalability, and high availability.

  • Non-blocking, Event-Driven Architecture

    An I/O model built for concurrency, handling thousands of simultaneous connections without spinning up a thread per request.

  • Real-Time by Design

    WebSockets and event streaming are native to the platform, not a bolted-on library fighting the runtime.

  • One Language, Full Stack

    TypeScript end to end — frontend, backend, and tooling share the same language and type definitions.

  • Massive Ecosystem

    The largest package ecosystem in the industry, for the problems every backend eventually has to solve.

  • Built for Microservices & Horizontal Scale

    Lightweight processes that start fast and scale horizontally, well suited to a microservices architecture.

  • Enterprise-Grade Reliability

    An architecture that holds up under real production traffic, with clustering and process management as standard practice.

What's Included

Everything under one roof

Everything included in this engagement, from architecture to long-term support — one team, one system.

REST APIs

Resource-oriented APIs designed to be consumed by web, mobile, and third-party clients alike.

Real-Time Applications

Live dashboards, collaborative tools, and streaming data interfaces built on persistent connections.

Marketplace Backends

Two-sided marketplace systems handling listings, transactions, and real-time inventory at scale.

Enterprise Software

Internal and customer-facing business systems architected for reliability and long-term maintenance.

AI Platforms

Backend services that orchestrate AI providers, manage streaming responses, and handle prompt logic securely.

Chat Systems

Real-time messaging and chat infrastructure built on WebSockets, with presence and delivery guarantees.

Notification Systems

Multi-channel notification delivery — push, email, SMS, and in-app — dispatched through a single event pipeline.

Payment Processing

Secure payment and subscription billing integrated with real payment providers.

Background Jobs

Reliable asynchronous processing for work that shouldn't block the request-response cycle.

Automation Platforms

Backend workflows that automate operational processes instead of relying on manual handoffs.
Why Aixo Lab

Why companies choose Aixo Lab

  1. We Architect for Concurrency, Not Just Convenience

    The event loop and async patterns are designed deliberately around your actual traffic shape, not left as framework defaults nobody revisits.

  2. We Build Real-Time Systems as a Core Capability

    WebSockets, connection state, and horizontal scaling for live features are architected up front, not retrofitted onto a request-response app.

  3. We Design Microservices Boundaries Deliberately

    Service boundaries follow real domain lines, not an arbitrary split that creates more coordination overhead than it removes.

  4. We Treat Background Work as First-Class Architecture

    Queues, retries, and failure handling are designed with the same rigor as the request path, not bolted on as an afterthought.

  5. We Hand Off Code Your Team Can Own

    Clear architecture and documentation mean your own engineers — or ours, later — can extend this codebase without archaeology.

Our Capabilities

Our Node.js Capabilities

The specific technical capabilities behind every Node.js engagement — not a generic feature list, the actual engineering surface we work in daily.

REST API Development

Resource-oriented API design built to the same standard whether it serves a web app, mobile app, or third party.

Microservices

Service boundaries drawn around real domain logic, with clear contracts between independently deployable services.

Event-Driven Architecture

Services that communicate through events rather than tight coupling, built for systems that need to evolve independently.

WebSockets

Persistent, bidirectional connections for real-time features, built to scale beyond a single server process.

Queue Systems

Message queues that decouple slow or unreliable work from the request cycle, with delivery guarantees that matter.

Background Workers

Dedicated worker processes for CPU-intensive or long-running tasks that shouldn't compete with request handling.

Authentication

Secure token and session-based authentication, integrated with role-based authorization.

File Processing

Reliable file upload, transformation, and storage pipelines for documents, media, and data files.

Scalability

An architecture that holds up as traffic, data volume, and team size all grow together.

High Availability

Clustering, health checks, and graceful failure handling designed so the system stays up under real conditions.

Performance Optimisation

Event loop profiling and memory management applied where they actually move the needle.

Technology Stack

Built on a modern, production-grade stack

Every technology here is a deliberate choice, not a default.

Node.js

The core runtime — a non-blocking, event-driven foundation built for concurrency and real-time systems.

TypeScript

Type safety across the entire backend, catching integration bugs before they reach production.

Express

A minimal, flexible framework for REST APIs when the project doesn't need a full opinionated structure.

NestJS

A structured, TypeScript-first framework for larger backends that benefit from enforced architecture.

PostgreSQL

The relational database of choice for applications that need advanced querying and strong data integrity.

Redis

Caching, session storage, and pub/sub messaging for workloads that need speed a database alone can't provide.

Docker

Containerized builds for consistent environments across development, staging, and production.

AWS

Cloud infrastructure for applications that need more control than a managed platform alone provides.

OpenAI

AI-assisted features — from backend orchestration to content generation — integrated via server-side APIs.

Stripe

Secure payment processing and subscription billing integrated directly into the backend.

Socket.IO

Real-time, bidirectional communication for chat, live dashboards, and collaborative features.

RabbitMQ

A message broker for reliable, decoupled communication between services and background workers.
Performance & Architecture

Performance & Architecture

The engineering decisions that determine whether a Node.js application stays fast and maintainable as it grows, not just at launch.

Event Loop Architecture

Non-blocking I/O patterns designed deliberately, so a single slow operation can't stall the entire process.

Service Boundary Design

Microservice boundaries decided during planning around real domain lines, not convenience or org-chart shortcuts.

Real-Time Connection Architecture

WebSocket and event-streaming infrastructure built to scale across multiple server instances, not just one.

Queue & Worker Architecture

Background work isolated from the request cycle, with retries and failure handling designed deliberately.

API & Service Design

Clear contracts between services and clients so the system stays organized as it grows past its first few endpoints.

Performance Optimisation

Event loop profiling, memory management, and load testing treated as measured engineering targets.

High-Availability Deployment Architecture

Clustering and deployment infrastructure that holds up as traffic and the codebase both grow together.
