Node.js Engineering

Node.js engineering for slow APIs and services that are hard to run.

We build Node.js APIs and integrations, and help teams work through slow requests, service failures, and rising infrastructure costs.

API and platform delivery

Node.js services, integration layers, internal platforms, and customer-facing APIs.

Prepare for service failures

Observability, incident routines, error handling, and production support patterns.

Performance and cost control

We focus on the slow requests and resource use that matter to your team.

Common problems

When to bring in our Node.js team

These are some of the problems we can help your team work through.

APIs slowing under load

We profile the API paths, data access, concurrency behavior, and downstream dependencies that affect customer experience.

Service complexity

We clarify service boundaries, contracts, ownership, and failure modes so the platform becomes easier to operate.

Cloud costs creeping up

We review resource use, background jobs, caching, and database access to look for avoidable cost.

Weak backend observability

We add practical metrics, traces, logs, alerts, and runbooks around the highest-risk workflows.

Legacy Node.js patterns

We standardize the important patterns and modernize the risky areas without freezing feature work.

Backend team overload

Senior Node.js engineers can lead focused platform work while your team keeps shipping the product roadmap.

Services

How we can help with Node.js

We can work on a specific problem or help your team carry a larger piece of the engineering work.

New Node.js APIs and services

We build Node.js APIs and services with clear interfaces, tests, and automated deployment.

Node.js rescue and modernization

We review older services, update dependencies, simplify difficult code, and plan changes in steps.

Performance and cost optimization

We investigate database access, caching, concurrency, queues, and resource use in the workloads causing problems.

Microservices and event-driven systems

We work on service boundaries, event contracts, queues, workers, retries, and idempotency, with monitoring to help your team understand failures.

Platform and integration engineering

We build internal tools, integrations, partner APIs, and shared services for work that needs to connect across systems.

Embedded Node.js team

Senior backend engineers work alongside your team, lead agreed platform work, review critical changes, and share what they learn.

Working together

How we plan the first 90 days

We agree what needs attention first, then work through the changes with your team.

  1. Assess the backend and workloads

    Review APIs, services, queues, database access, incidents, traffic shape, and team workflow.

  2. Agree on a 90-day platform plan

    Agree which failures, slow requests, costs, and integration problems need attention first.

  3. Stabilize production paths

    Fix recurring failures, improve logging and alerts, and document how to respond when services fail.

  4. Optimize hot services

    Tune high-traffic paths, background work, caching, resource usage, and deployment shape.

  5. Share the changes with your team

    Document service conventions and work through key changes with your team.

Your existing tools

Work with the system you already have

We review the code and tools already in use before recommending changes.

  • Node.js LTS versions with TypeScript or JavaScript
  • Express, NestJS, Fastify, REST, GraphQL, gRPC, and lightweight custom stacks
  • PostgreSQL, MySQL, MongoDB, Redis, RabbitMQ, Kafka, and managed cloud services
  • AWS, GCP, Azure, containers, serverless platforms, and CI/CD pipelines
  • Logs, metrics, tracing, error tracking, runbooks, and incident reviews
Our approach

How we approach the work

The support migration below shows our approach to moving forum data and connecting user identities across systems.

Start with the workflows people depend onWe discuss which customer tasks are affected, what happens when a service fails, and what it costs to run.
Clear service boundariesWe make APIs, integrations, queues, and ownership easier to reason about before adding more complexity.
Make the backend easier to runThe result should be a backend your team can monitor, debug, deploy, and improve with confidence.

FAQ

Node.js questions we hear often

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

No. We work with older Node.js services, mixed frameworks, and incremental modernization paths.

Can you modernize an existing Node.js backend instead of rebuilding it?

Yes. We usually stabilize and standardize the current platform before recommending any larger rewrite.

Do you help with microservices and queues?

Yes. We work on service boundaries, event contracts, retries, idempotency, observability, and operational routines.

Can you reduce API latency and infrastructure cost?

We profile requests, database access, background work, and resource use to find where changes may help.

How do Node.js engagements usually start?

We begin by reviewing the backend and the problems you are seeing, then agree on the work and timeline.

Next step

Is your Node.js team spending too much time on slow requests or incidents?

Tell us which requests or services are causing trouble and what you have tried. We can discuss where to start.
