Node.js & API Development

APIs and backend systems that handle what you throw at them

RESTful APIs, GraphQL, WebSockets, and event-driven architectures built on Node.js. We design backend systems that are fast, reliable, and straightforward to operate.

Why Node.js

01

JavaScript everywhere

One language across your entire stack. Shared types, shared validation logic, shared utilities. Your frontend and backend teams speak the same language. Literally.

02

Async by nature

Node.js handles I/O-heavy workloads efficiently. API gateways, real-time features, webhook processors. The event loop handles thousands of concurrent connections without thread management overhead.

03

Ecosystem that moves fast

npm has a package for nearly everything. But we're selective. We audit dependencies, minimize supply chain risk, and build custom when the existing options are bloated or poorly maintained.

What We Build

REST and GraphQL APIs

Well-documented APIs with OpenAPI specs or GraphQL schemas. Rate limiting, authentication, versioning, and error handling designed for real-world consumption.

Real-time systems

WebSocket servers, Server-Sent Events, and pub/sub architectures for live dashboards, chat systems, and notification pipelines.

Microservices and event-driven architecture

Service decomposition, message queues with Redis or RabbitMQ, and event sourcing patterns. We split monoliths when scale demands it, not before.

Database design and optimization

PostgreSQL, MongoDB, Redis. Schema design, query optimization, connection pooling, and migration strategies. The database is where most performance problems live.
