Node.js Development Services
Build scalable, high-performance backends with Node.js — REST APIs, GraphQL servers, real-time WebSocket services and event-driven microservices, delivered TypeScript-first and production-hardened.
Node.js API Development — REST & GraphQL
We build Node.js APIs that handle production traffic reliably: Express or Fastify for REST, Apollo Server or Pothos for GraphQL, with consistent error handling, input validation and OpenAPI documentation generated from the code rather than maintained by hand.
Node.js API Development — REST & GraphQL
We build Node.js APIs that handle production traffic reliably: Express or Fastify for REST, Apollo Server or Pothos for GraphQL, with consistent error handling, input validation and OpenAPI documentation generated from the code rather than maintained by hand.
- Express.js and Fastify for high-throughput REST API services
- Apollo Server 4 or Yoga for GraphQL with DataLoader for N+1 elimination
- tRPC for type-safe end-to-end API contracts in full-stack TypeScript monorepos
- Zod or Joi schema validation on all request inputs
- OpenAPI 3.x documentation with Swagger UI and client SDK generation
- JWT, OAuth 2.0 and API-key authentication with rate-limiting middleware
NestJS for Enterprise Node.js Applications
NestJS brings Angular-style module structure, dependency injection and decorators to Node.js — which matters for large teams where conventions prevent architectural drift. We use NestJS for complex domain services where the structure justifies the overhead.
- NestJS modules, controllers, services and guards with TypeScript
- CQRS pattern with NestJS CQRS module for complex domain models
- Bull or BullMQ for job queues with priority, retry and dead-letter queues
- Prisma or TypeORM with NestJS for type-safe database access
- NestJS microservices with RabbitMQ, Kafka or NATS transport
- OpenTelemetry tracing with Jaeger or Grafana Tempo integration
Real-Time & Event-Driven Architecture
Node.js’s event loop and non-blocking I/O make it the right choice for real-time applications — chat, live dashboards, collaborative editors and WebSocket notification systems. We design event-driven backends that stay responsive under concurrent connection loads.
- WebSocket servers with Socket.io or native ws for real-time bidirectional data
- Server-Sent Events (SSE) for one-way live updates without WebSocket overhead
- Redis Pub/Sub for multi-process and multi-instance event distribution
- Kafka or RabbitMQ consumers for high-throughput event-streaming pipelines
- Webhook delivery engines with exponential backoff and dead-letter storage
- CQRS and event sourcing for audit-trail-critical domains
Database Integration & Performance
Node.js backend performance is mostly a database performance problem. We choose the right database for the query patterns, design schemas for the reads not the writes and optimise slow queries before they become production incidents.
- PostgreSQL with Prisma ORM — type-safe queries and auto-generated migrations
- MongoDB with Mongoose for document-oriented, schema-flexible data
- Redis for session storage, caching, rate-limiting and pub/sub
- Connection pooling with PgBouncer or Prisma accelerate for serverless Node
- Slow-query analysis and index recommendations from EXPLAIN ANALYZE
- Read replicas and connection routing for high-read-load API services
Production Deployment, Observability & Security
A Node.js service that works on a developer’s laptop is not a production service. We containerise, deploy with health checks and rolling updates, instrument with structured logging and set up alerting so on-call engineers see problems before users report them.
- Docker containerisation with multi-stage builds for minimal image size
- AWS ECS, GKE or DigitalOcean App Platform deployment with auto-scaling
- PM2 cluster mode for multi-core utilisation on VPS deployments
- Structured JSON logging with Pino — ingested by Datadog, Grafana Loki or CloudWatch
- Sentry for error tracking with async context propagation
- OWASP Node.js security baseline: helmet, CORS, CSRF, rate-limiting, secret scanning
Senior engineers, modern stacks, no hand-offs.
From greenfield products to long-running platforms — we build software that survives launch day and the year that follows.
Custom development
TypeScript, Node, Laravel, .NET — picked for the workload, not the resume.
- Clean-architecture by default
- Test coverage on critical paths
- Type-safe end to end
API & micro-services
REST, GraphQL and event-driven services with documented contracts.
- OpenAPI / GraphQL schemas
- Versioned + backwards-compatible
- Rate-limited + cached
Data layer
PostgreSQL, Mongo, Redis — modelled for the actual access patterns, not the ORM.
- Read replicas + sharding
- Migrations as code
- PII-aware schemas
Security baked in
OWASP-aligned reviews, secrets in vaults, dependency scans on every build.
- SAST + DAST
- Dependency CVE watch
- Audit-friendly logs
Predictable, audit-friendly delivery.
Every engagement follows the same stage cycle — so you always know what is happening, what comes next, and who owns it.

Replatform that scaled to 4× peak traffic.
A B2B SaaS replatform onto a modern TypeScript stack — shipped in 14 weeks with zero data loss and a 64% drop in P95 latency.
The tools we ship with.
Engineering that survives the first production weekend.
Most software fails not at launch but six months in — when traffic spikes, requirements drift and the original team rolls off. We design for that reality from sprint zero.
Architecture chosen for the workload
We pick a stack against the actual access patterns, expected load and team skill — never against trend cycles. The result is fewer rewrites, lower hosting bills, and a codebase your future engineers can navigate in an afternoon.
Tests where they pay off
Critical paths are covered with integration and contract tests; trivial getters are not. We aim for confidence at deploy time, not coverage-percentage theatre — and we wire CI to block regressions, not vanity metrics.
Observability from day one
Every service ships with structured logs, distributed traces and business-KPI dashboards. When something breaks at 2 a.m., your on-call has the timeline, the request and the user — not a haystack.
Documentation that engineers actually read
Architecture decision records, runbooks and onboarding paths live next to the code. New engineers contribute on day three, not week three — and audits stop being a fire drill.
How we make decisions.
Four non-negotiables that govern every engineering choice we make — from stack selection to incident response.
AI-assisted code review
Every pull request runs static analysis and ML-pattern checks before a human reviewer sees it — so engineers spend their review time on logic, not linting.
Observability first
Structured logs, distributed traces, RUM and alerting are wired in from sprint one. When something breaks at 2 a.m., the on-call has the full picture in seconds — not a blank Datadog screen.
Outcome-tied KPIs
Every sprint is reviewed against the business metric it was meant to move — conversion rate, latency, error budget — not story points or lines of code delivered.
Resilient architecture
Graceful degradation, idempotent retries, dead-letter queues and circuit breakers are default patterns, not afterthoughts. Systems that fail quietly are more dangerous than systems that fail loudly.
Three ways to work with us.
End-to-end delivery against a clear scope — discovery through launch with signed-off milestones at every sprint.
