Node.js backends and API that handle whatever you throw at them.

We have been building Node.js backends since 2013. TypeScript throughout. NestJS for enterprise structure. 300+ backend systems shipped. REST, GraphQL, WebSockets, microservices — we build the API layer that every mobile app, web app, and third-party integration depends on.

What we build with Node.js

Six backend use cases — each with the right NestJS, Express, or Lambda architecture chosen for the problem.

REST APIs

Versioned REST APIs for mobile apps, web applications, and third-party integrations. OpenAPI/Swagger documentation, authentication, rate limiting, request validation, and comprehensive error responses.

NestJS · OpenAPI · Prisma · PostgreSQL

GraphQL APIs

Schema-first GraphQL with Apollo Server. DataLoader for N+1 prevention, subscription support for real-time data, and code-first schema generation from TypeScript types.

Apollo Server · DataLoader · TypeScript · Subscriptions

Real-Time Backends

WebSocket servers for live chat, collaborative editing, real-time dashboards, and multiplayer features. Socket.IO or native ws, Redis pub/sub for horizontal scaling.

Socket.IO · EAS Build · Redis pub/sub · WebSockets . NestJS

Microservice Architectures

Independently deployable NestJS services with their own databases, communicating via REST (sync) or SQS/EventBridge (async). Service boundaries designed thoughtfully.

NestJS · SQS · EventBridge · Docker ECS

Serverless Functions

AWS Lambda for event-driven processing, scheduled jobs, webhook handlers. TypeScript Lambda with cold start optimisation and full observability.

AWS Lambda · API Gateway · TypeScript · CloudWatch

Backend-for-Frontend (BFF)

Dedicated backend service aggregating data from multiple microservices or third-party APIs into the exact shape each frontend client needs.

NestJS · GraphQL · tRPC · Redis

Who hires us

Mobile and web teams whose API is the bottleneck

Your iOS or web app is fast. Your API is not. We audit, identify the query patterns and architectural issues causing latency, and rebuild the backend for the throughput you need.

Startups scaling their backend for the first time

The single Express server that worked at 100 users starts behaving unexpectedly at 100,000. We design the architecture that takes you from MVP to scale without a complete rebuild.

Teams building microservice architectures

Decomposing a monolith or designing a new microservice platform. We design service boundaries thoughtfully — not every project needs microservices — and implement the patterns that make microservices manageable.

Engineering leads evaluating Node.js vs Python or .NET

The right backend language depends on your team, your integration requirements, and your performance profile. A free technical consultation will give you an honest comparison for your specific situation.

NestJS by default.
TypeScript strict.
Security is the foundation.

Four things that separate EB Pearls Node.js engineering from Express shops with an opinioned README.

NestJS for structure — Express for lightweight

We default to NestJS for any backend beyond a simple API. Its dependency injection, module system, and decorators enforce consistent architecture across the team. For simple services or Lambda functions, Express or Fastify. The choice is explicit and reasoned.

TypeScript, strict mode, non-negotiable

All Node.js projects are TypeScript with strict mode. Runtime type validation with Zod at API boundaries. Type-safe database queries with Prisma or TypeORM. A type error at compile time is infinitely cheaper than a type error in production at 2am.

Security is not a feature — it is the foundation

Input validation, parameterised queries, rate limiting, JWT rotation, secrets in AWS Secrets Manager, dependency auditing in CI, and OWASP API Top 10 review. We have seen what happens when security is added later.

We design for operational reality

Structured logging, distributed tracing with X-Ray, health check endpoints, graceful shutdown, circuit breakers, and retry logic with exponential backoff. The difference between a backend that works in staging and one that works in production at scale.

NestJS vs Express — when each is right

The difference matters at scale. Express for lightweight; NestJS for anything that will be maintained by a team.

Dimension	Express / Fastify	NestJS (EB Pearls default)
Dependency injection	Manual — roll your own	✓ First-class DI container
Module system	Flat — everything imports everything	✓ Enforced module boundaries
OpenAPI docs	Third-party plugin required	✓ @nestjs/swagger — first-class
Guards & interceptors	Custom middleware	✓ Built-in — consistent pattern
Testing setup	Manual mocking setup	✓ Testing module — mocks resolved via DI
Best for	Lightweight Lambda functions	✓ Production APIs maintained by teams
Learning curve	Low	Moderate — pays back at scale

EB Pearls created a unique and special website and web design agency, perfect for our customers. We loved the team’s efficiency in creating us great user experience and a seamless website design plan, with beautiful on-brand illustrations. The team were patient, professional and always there to guide us and I wouldn’t hesitate to recommend them and work with them again in the future.

Julia Kish

Manager, Intellihub

Approachable and accommodating to our exact needs and requirements. Our mobile app’s reception and engagement have been great, and the design is very user-friendly. EB Pearls is very professional, always on track, and always delivers to our expectations.

Roberto Peresa

Founder, Aguzzo Group

We came to EBPearls with a precise design remit, which they took on board and produced for us on time and on budget. It was a pleasure to have our feedback accepted and acted upon swiftly, and any concerns we had addressed promptly. We love our new website, and the accessibility it offers to our diverse audience.

Dr Melanie Heyworth

CEO & Founder, Reframing Autism

I’m a solo entrepreneur and not very good with tech. EB Pearls made it easy, mentoring me through everything. Highly recommend!

Charmaine Hilario

Founder, Whitebow Gift registry

We were very happy with all of the work undertaken during each phase of our new website production. All EB Pearls personnel were knowledgeable, approachable and helpful – we were also most impressed with the professionalism and responsiveness they demonstrated throughout the process.

Coral Funnell

Marketing Manager, Rotech

We’re extremely impressed with EB Pearls’ work, technical skill, and ability to adapt, iterate, and learn new skills. Their high attention to detail and eternally positive attitude make working with EB Pearls a wonderful experience.

Sarah Scaife

Product owner, BAXTA

EB Pearls do high-quality work in the allotted timeframe. They maintain clear and consistent communication, providing updates on key project components and listening to feedback. There are numerous different stages, processes, and statuses in our project which made the work very complicated, but EB Pearls worked it all out.

Can't find what you need?

Node.js for high-throughput I/O-bound APIs, real-time features, and JavaScript teams. Python for ML serving, data pipelines, and AI-native backends.

REST for CRUD, third-party integrations, and public APIs. GraphQL for complex client data requirements where different views need different shapes.

Input validation with Zod, parameterised queries, rate limiting, JWT rotation, secrets in AWS Secrets Manager, npm audit in CI, OWASP API Top 10 review.

Yes — strict mode, all projects. Zod at API boundaries. Prisma or TypeORM for type-safe database queries.

Structured logging, distributed tracing with X-Ray, health check endpoints, graceful shutdown, circuit breakers, and retry logic with exponential backoff.

PostgreSQL as our primary via Prisma or TypeORM. DynamoDB for high-throughput NoSQL. Redis for caching. Database selection is driven by the data model.

Express is minimal and unopinionated. NestJS is opinionated with DI, modules, and decorators that enforce consistency. We default to NestJS for any backend beyond a simple API.

NestJS in Docker on ECS, with its own database per service. Services communicate via REST (sync) or SQS/EventBridge (async). Independent CI/CD per service.

Simple REST API: AUD $25,000–$60,000. Full SaaS backend: $60,000–$150,000. Microservice architecture: $150,000–$350,000+.

A Backend-for-Frontend aggregates data from multiple services or third-party APIs into the exact shape each frontend client needs. Reduces over-fetching and simplifies frontend logic.

Yes — WebSocket servers for live chat, collaborative editing, real-time dashboards. Socket.IO or native ws, Redis pub/sub for horizontal scaling.

Yes — AWS Lambda for event-driven processing, scheduled jobs, webhook handlers. TypeScript Lambda with cold start optimisation and full observability.
