Asynchronous Server Systems

Our Node.js engineering team constructs high-performance, real-time applications using event-driven, non-blocking I/O models.

We work with proven frameworks like Express.js, NestJS, and Fastify. We unify your stack under the ubiquitous JavaScript ecosystem—improving cross-team communication between frontend (React) and back-end logic.

From real-time chat and streaming to large microservice estates, we build Node.js backends for data-heavy, real-time applications.

Our Node.js Ecosystem Competence

We work across the JavaScript ecosystem - building backend APIs, deploying cloud infrastructure, and working with large NoSQL and SQL databases.

Express & NestJS

We build nimble route configurations with the industry-standard Express.js environment perfectly suited for lean setups. For massive enterprise applications, we leverage NestJS—providing Angular-like Dependency Injection, heavy TypeScript integrations, and modular application structures to avoid spaghetti architecture at a large scale.

Data Engineering

Fast, well-structured data access is at the heart of every backend. We connect Node to MongoDB through Mongoose when a flexible document model fits, and use ORMs like Prisma or TypeORM to connect services to scalable PostgreSQL infrastructures.

Node.js Engineering Services

From isomorphic JavaScript stacks to decoupled REST architectures powering mobile applications.

API Development & Architecture

We build fast, versioned REST and GraphQL endpoints. Node's non-blocking I/O lets one service handle large numbers of concurrent requests efficiently.

Real-Time WebSocket Servers

Leveraging Socket.IO to build highly responsive two-way communication channels necessary for live trading terminals, multiplayer applications, and chat systems.

Serverless Architectures

We wrap scalable Node modules into AWS Lambda deployments or Azure Functions, so you pay for actual usage rather than idle servers.

3rd-Party API Gateways

Build API gateways and reverse proxies that connect legacy platforms with external services and webhooks, secured with OAuth 2.0.

Microservices Architectures

Break monoliths into Node.js services in Docker containers, orchestrated with Kubernetes or a managed container service.

DevOps & CI/CD Pipelines

Automate Jest/Mocha test suites and set up GitHub Actions or GitLab pipelines that run tests, linting and security checks before every deployment.

Engagement Models

Flexible Ways to Work With Us

Every client relationship is different. We offer three engagement models to suit different team sizes, budgets, and timelines.

Dedicated Resource Model

A full-time, dedicated Node.js developer embedded in your team who works with AI tools for API scaffolding, CRUD and test generation. You direct their work daily; they join your stand-ups, sprints and code reviews like an in-house hire and review every AI-assisted change.

Fixed Price Model

A defined scope, fixed timeline, and a fixed budget. Best for well-specified projects where requirements are stable. We provide a detailed SoW, milestone payments, and a sign-off process at each delivery phase.

Time & Material Model

Pay only for the hours worked, with full transparency via weekly timesheets and detailed task logs. Ideal for evolving products where scope changes frequently and you need maximum flexibility to reprioritise.

Pixel & Bots

Pixel-perfect software, delivered at AI speed

PixoBots stands for Pixel & Bots. Our Bots are dedicated developers who work with AI tools: AI takes the repetitive work, a developer reviews every line, and the result is pixel-perfect.

Pixel

Polished UI and clean, tested code - detail is part of the job, not an afterthought.

Bots

Dedicated developers who join your team and use AI for boilerplate, tests and documentation.

Savings

AI-assisted delivery can save more than 50% of development cost compared with traditional development.

help_outline FAQ

Frequently asked questions

Is Node.js a good choice for our back end? expand_more
Yes, Node.js is a strong fit for APIs, real-time features such as chat and live updates, and I/O-heavy services, and it lets one TypeScript skill set cover both front end and back end. For heavy CPU work such as video processing or large computations, we offload to worker threads, background jobs or services in other languages.
Express, NestJS or Fastify: which framework should we use? expand_more
We choose per project. NestJS suits larger applications that benefit from structure, dependency injection and TypeScript conventions. Fastify is ideal for high-throughput APIs with low overhead. Express remains a simple, widely understood option for small services. All three are mature, so team familiarity and long-term maintainability usually decide.
How much does Node.js development cost? expand_more
The cost depends on scope. The main drivers are the number of endpoints and features, third-party integrations, real-time requirements, data and security needs, expected traffic and whether you need a dedicated team or a fixed project. PixoBots quotes after a short discovery call and prices by milestone, and you own all the code and IP.
Can Node.js scale to high traffic? expand_more
Yes. Node.js handles many concurrent connections efficiently thanks to its non-blocking I/O, and it scales horizontally by running multiple instances behind a load balancer, in containers or as serverless functions. We add Redis caching, message queues for background work and database tuning, and load-test before launch to confirm capacity.
Can you upgrade our legacy Node.js application? expand_more
Yes. We upgrade apps on end-of-life Node.js versions to a current LTS release, update or replace outdated dependencies, fix vulnerabilities flagged by npm audit, and migrate JavaScript to TypeScript where it adds safety. Automated tests are added first, and changes ship in small steps so the application can stay live while it is modernised.
