When to bring in our Node.js team?

If any of these sound familiar, you’re exactly the kind of team we help.

APIs slowing under real-world traffic

Latency spikes, timeouts, and brittle endpoints show up once real users arrive, and nobody has time to profile or optimize.

Legacy or messy Node.js services

A mix of different styles, frameworks, and patterns makes every change risky and every deployment stressful.

Microservices or queues out of control

“Just one more service” has turned into dozens of Node.js services, queues, and workers that are hard to reason about or debug.

Backend team stretched too thin

Product pressure, tech debt, and operational firefighting all collide. Senior engineers don’t have the space to improve the foundations.

No clear observability or incident process

When production breaks, you’re chasing logs across services, guessing at root causes, and relying on heroics to keep things running.

Cloud and infra costs creeping up

Node.js services scale horizontally… and so do your bills. You know there’s waste, but don’t have a structured way to fix it.

Node.js services

From core APIs to event-driven systems, we plug into your Node.js stack where it matters most.

New Node.js product builds & APIs

We design and build Node.js APIs and backends for new products: architecture, patterns, testing, and CI/CD so your team can keep shipping safely.

Node.js rescue & modernization

We audit your current Node.js stack, reduce complexity, standardise patterns, and create a pragmatic modernization roadmap instead of a risky rewrite.

Performance & cost optimisation

We profile your services, tune hot paths, optimize database access and caching, and right-size infra so your app is both faster and cheaper to run.

Microservices & event-driven architectures

We help you design and implement Node.js-based microservices and event-driven systems with clear boundaries, contracts, and observability.

Platform & integration engineering

We build Node.js-based integration layers, internal platforms, and tooling so your product teams move faster with less duplication.

Embedded Node.js team (staff augmentation)

Senior Node.js engineers embed with your team to lead key initiatives, review critical code, and mentor your in-house engineers.

Our Node.js playbook

We don’t just write JavaScript, we bring a structured, revenue-first playbook to every backend engagement.

Assess – Backend & system audit

Review your Node.js architecture, services, APIs, and data flows

Profile performance, reliability, and incident history across key workloads

Output: audit report + prioritised issues

Align – 90-day value plan

Co-design a 6–12 week roadmap focused on reliability, speed, and costs

Decide where to invest first: critical flows, infra, observability, or refactors

Output: clear backlog with measurable outcomes

Stabilize – Make production boring

Address the most painful incidents and recurring failures

Improve logging, metrics, alerts, and basic runbooks around Node.js services

Output: fewer fire drills, more predictable releases

Optimize – Performance & efficiency

Optimize database access, caching, concurrency, and resource usage

Streamline local development, testing, and CI for Node.js

Output: faster APIs, happier customers, and lower run-costs

Grow – Enable your team

Pair programming, reviews, and architecture guidance with your engineers

Document conventions, patterns, and guardrails for future Node.js work

Output: a stronger team that can keep improving without us

Node.js stack we work with

We plug into modern, production Node.js environments and the ecosystems around them.

Node.js (LTS versions) with TypeScript or JavaScript
Frameworks like Express, NestJS, Fastify, and custom lightweight stacks
Databases: PostgreSQL, MySQL, MongoDB, and other common datastores
Caching and queues: Redis, RabbitMQ, Kafka, and managed cloud services
REST and GraphQL APIs, gRPC, and event-driven messaging
CI/CD pipelines with GitHub Actions, GitLab CI, CircleCI, etc.
Observability: logs, metrics, tracing, and error tracking for distributed Node.js services
Deployments on AWS, GCP, Azure, containers, and serverless platforms

For you, this means we can meet your backend stack where it is today, not force a shiny greenfield blueprint that ignores reality.

What our clients say

RocketApex has been truly awesome to work with. There's a tremendous number of software vendors to choose from and making the initial decision was difficult, but after a few communications, I chose RocketApex and I can't imagine I could have made a better decision. Their speed and expertise has been invaluable and it does not seem possible that another vendor could have been better. Thank you RocketApex for your great communication, expertise, and professionalism."

Chris Cunningham

Sales Director, North Carolina, United States

Intelatek Inc

I had the pleasure of working with RocketApex and was impressed with their exceptional technical skills, attention to detail, and commitment to quality.

The consultants demonstrated a deep understanding of Ruby on Rails, quickly identifying and resolving any issues that arose during the project. They were proactive in suggesting improvements and optimizations to our codebase, making our application faster and more efficient.

Their communication skills were excellent, always keeping me updated on the project's progress and making collaboration effortless.

Overall, I highly recommend RocketApex to anyone seeking a reliable and skilled Ruby on Rails team.

Florian Felsing

Chief Technology Officer, Germany

Global Commerce Media GmbH

RocketApex was great! They competently got the job done, was great at communicating, and clearly is a talented software vendor. I am a software engineer myself and they understood the requirements exactly and got the job done well.

Why teams choose RocketApex for Node.js

There are many Node.js partners. Here’s what our clients say sets us apart.

Revenue-first delivery

We don’t optimize Node.js for its own sake. We connect backend decisions to revenue, reliability, and efficiency across your product.

Mid-market specialization

We’re built for companies beyond “early startup”, but not yet “enterprise bureaucracy”. Roadmaps, communication, and pricing that fit $10–250M businesses.

Opinionated but pragmatic Node.js architecture

We use patterns that work: clear service boundaries, well-defined contracts, and maintainable code, not over-engineered complexity.

Reliability and observability by default

We care about error budgets, alerts, and incident handling so your systems stay predictable instead of depending on heroics.

Embedded collaboration, not black-box outsourcing

We pair, review, and coach. Your team gets stronger while the platform gets better.

Node.js FAQ

Do you only work with the latest Node.js version?

No. We regularly work with apps on older Node.js versions and different styles. We help you modernise incrementally rather than insisting on a risky big-bang rewrite.

Can you help us modernise an existing Node.js backend instead of rebuilding?

Yes. Modernization is one of our core strengths. We prefer to stabilize, refactor, and incrementally improve where possible, and only recommend rewrites in narrow, justified cases.

How quickly can you start on a Node.js rescue or performance project?

After an initial call and a short discovery, we usually begin with a focused Node.js and system audit. From there, we define a 6–12 week plan with you before expanding scope.

Will you replace our engineering team?

Usually not. Most of our engagements involve working closely with an existing team, pairing, reviewing, and leading certain backend initiatives, so the team is stronger at the end of the engagement than at the start.

How do you price Node.js work?

We use simple engagement models: outcome-based projects for well-scoped work, and dedicated pods for ongoing platform development. We’ll recommend a model after understanding your roadmap and constraints.

Do you offer ongoing support and SLAs for Node.js platforms?

Yes. We can provide ongoing support and SLAs for production Node.js services, typically paired with continuous improvement work so the platform keeps getting better, not just “kept alive”.
