Your Backend Keeps You Awake. We Build the One That Doesn't.

If you're a founder rebuilding the same Express routes every sprint, you've hit the architecture ceiling. We ship production Node.js backends that scale without the 3am alerts.

Production-grade Node.js backends for SaaS, realtime apps, and microservices. PostgreSQL, Redis, queues, webhooks, and observability included.

What Is Node.js Backend Development?

Node.js backend development is about building the server-side layer that everything else depends on -- APIs, microservices, event-driven systems. Frameworks like Express, Fastify, and NestJS handle the core work: managing concurrent connections, routing requests, structuring your application logic. Add PostgreSQL for persistence, Redis for speed, and a proper queue system, and you've got the foundation that SaaS platforms and distributed systems actually run on.

Your Current Site May Be a Liability

Common gaps we find in nearly every audit.

Your REST API holds up fine in development, then falls apart the moment real traffic hits
Risk: Users aren't waiting around for dashboards that take 3+ seconds to load. Every 100ms of added latency is quietly costing you conversions.
Payment webhooks fail
Risk: Data pipelines drop records. There's no retry logic, no error handling worth the name -- just silent failures that show up later as lost transactions and corrupted state.
You've got a monolith nobody wants to deploy
Risk: Feature development slows to a crawl. Every release feels like you're defusing something.
Background jobs running on cron scripts or setTimeout calls vanish on restart, can't be retried, and give you no visibility into what failed or why
Risk: You find out something went wrong when a customer complains.
Your monitoring is console.log
Risk: Customers report outages before your own tools do. Mean time to recovery stretches into hours because you're flying blind.
Unindexed queries, full table scans on every request, and a database bill that went from $200 to $2,000 before you noticed
Risk: PostgreSQL can do a lot -- but not without a little help.

How We Build This Right

Every safeguard, built in from Day 1.

Framework Selection

We pick Express, Fastify, or NestJS based on what the project actually needs. Fastify for raw throughput. NestJS for teams that need consistent structure across a large codebase. Express when ecosystem compatibility matters more than anything else.

Database Architecture

PostgreSQL schema design with Prisma ORM, proper indexing, and migration workflows you can actually trust. Supabase integration for auth, storage, and realtime subscriptions when it fits.

Redis & Caching Layer

Redis for session management, response caching, rate limiting, and pub/sub. Cache invalidation strategies that hold up under real production conditions -- not just in theory.

Queue Processing

BullMQ job queues with retry logic, dead letter queues, priority scheduling, concurrency limits, and a monitoring dashboard. Background jobs that survive restarts and can be inspected when something goes wrong.

Webhook Architecture

Inbound and outbound webhook systems built with signature verification, idempotency keys, exponential backoff, and delivery logging. No more silent failures.

Production Observability

Structured logging, distributed tracing, custom metrics, and alerting wired into Grafana, Datadog, or whatever you're already running. OpenTelemetry instrumentation that actually tells you what's happening inside your system.

What We Build

Purpose-built features for your industry.

TypeScript-First APIs

Every endpoint is fully typed -- request validation through Zod, response serialization, generated OpenAPI docs. Your frontend team gets a spec they can use immediately.

Realtime WebSocket Support

Socket.IO or native WebSocket implementations for live dashboards, chat, notifications, and collaborative features. Real-time that works at scale.

Authentication & Authorization

JWT, OAuth 2.0, API key management, and role-based access control. We use Supabase Auth where it makes sense and custom implementations where it doesn't.

Microservices Communication

Event-driven architecture with message brokers, gRPC for internal service communication, and API gateway patterns for external consumers.

CI/CD & Docker

Multi-stage Docker builds, GitHub Actions pipelines, and zero-downtime deployment strategies. Nothing goes down during a release.

Load Testing & Benchmarking

Artillery and k6 load tests are part of the process, not an afterthought. You'll know your system's breaking point before your users find it for you.

Our Development Process

From discovery to launch. Quality at every step.

01

Architecture Audit

Week 1

We start by reviewing your existing backend -- or your requirements if you're building from scratch. We map the bottlenecks, design the architecture, and hand you a technical spec with data flow diagrams before anything gets built.

02

Schema & API Design

Week 2

Schema design, API contracts defined with OpenAPI specs, authentication flow planning. Everything gets documented and signed off before a line of code gets written. No surprises later.

03

Core Implementation

Weeks 3–5

Framework setup, database migrations, core API endpoints, background job infrastructure, webhook handlers. Test coverage ships alongside every feature -- not as a follow-up task.

04

Observability & Hardening

Week 6

Structured logging, error tracking, health checks, rate limiting, load testing. We find the failure modes in staging, not production.

05

Deployment & Handoff

Week 7

Production deployment with monitoring dashboards, runbook documentation, and 30 days of post-launch support. Your team gets a full walkthrough of the codebase so they're not inheriting a black box.

Frequently Asked Questions

Express has the largest middleware ecosystem and almost no learning curve — it's the safe default for most projects. Fastify runs 2-3x faster, which matters for high-throughput APIs where every millisecond counts. NestJS brings opinionated structure — dependency injection, modules, decorators — and it's the right call for large teams managing dozens of services where consistency matters more than raw speed.
We use Prisma Migrate for schema versioning. The workflow is strict: generate migrations in development, review them in pull requests, test in staging, apply to production during deployment. Destructive changes follow a multi-step process — add the new column, backfill the data, update the application code, then drop the old column. Nothing goes down.
Structured JSON logging with request correlation IDs, distributed tracing across services via OpenTelemetry, custom business metrics like signup rates and payment success, health check endpoints, and alerting rules. Grafana or Datadog dashboards give you request latency, error rates, and queue depths at a glance. You stop finding out about problems from customers.
Yes. We build against an OpenAPI spec your frontend team can use from day one. TypeScript client SDKs get generated from that spec, so your React or Next.js frontend gets type-safe API calls without anyone typing them by hand. CORS, authentication tokens, WebSocket connections — all handled.
We use BullMQ backed by Redis. Every queue gets retry logic with exponential backoff, dead letter queues for failed jobs, priority scheduling, concurrency limits, and a monitoring dashboard. Jobs survive server restarts. You can inspect, retry, or cancel them through the admin UI — no digging through logs to figure out what happened.
REST is request-response: the client asks, the server answers, the connection closes. WebSockets keep that connection open so the server can push data the moment something changes — which is what you need for live dashboards, chat, notifications, and collaborative editing. Most apps use both: REST for standard CRUD operations, WebSockets for realtime updates, sharing the same authentication and business logic underneath.
