What We Build

Six Categories of Node.js Work, Shipped to Production

From greenfield Express APIs to real-time WebSocket platforms and serverless functions. Same senior team, same code review bar.

  • Custom Node.js APIs

    Greenfield Express, NestJS, or Fastify APIs with TypeScript end to end. OpenAPI specs, validation with Zod, structured logging, and rate limiting built in from sprint one.

  • Real-Time Systems

    Socket.IO and native WebSockets for chat, presence, live dashboards, and trading consoles. Sub 50ms tick latency under load with Redis pub/sub and horizontal scaling.

  • Serverless Node on AWS Lambda

    Lambda functions in TypeScript, API Gateway, EventBridge, Step Functions. Cold start tuning, bundle minimisation, and observability with CloudWatch and X-Ray.

  • Node Microservices

    Polyglot microservices with Node services for the high-throughput surfaces. Service discovery, gRPC or HTTP, message queues with Kafka or RabbitMQ, distributed tracing.

  • GraphQL with Apollo

    Apollo Server, schema-first design, DataLoader for batching, persisted queries for security. Federation when you need to compose multiple subgraphs.

  • Node.js Modernisation

    Migrate legacy Express apps to NestJS or Fastify. Upgrade Node 14 or 16 to 22 LTS. Convert callbacks to async/await. Reproducible builds with esbuild or tsx.

Reference Stack

A Node.js Stack That Survives Traffic Spikes

Six layers we wire together on greenfield Node.js projects. Each layer is observable, replaceable, and tested in isolation.

  • Layer 01

    Runtime

    Node.js 22 LTS

    Long-term support runtime, ESM-first, native fetch, structured clone, AbortController

  • Layer 02

    Framework

    NestJS, Express, Fastify

    NestJS for structured monoliths, Fastify for performance, Express for legacy or lightweight

  • Layer 03

    Data

    Postgres, MongoDB, Redis

    Prisma or Drizzle ORM, connection pooling, point-in-time recovery, snapshot backups

  • Layer 04

    Messaging

    Kafka, RabbitMQ, SQS, NATS

    Async event flow, dead-letter queues, replay tools, schema validation

  • Layer 05

    Real-time

    Socket.IO, native WebSockets

    Horizontal scaling with Redis adapter, room-based broadcast, sticky sessions

  • Layer 06

    Observability

    OpenTelemetry, Pino, Datadog

    Structured logs, distributed traces, RED metrics, correlation IDs end to end
