Technology

Node.js Backend Development

Scalable Node.js APIs and backend services for startups. REST, GraphQL, real-time systems, and cloud-native infrastructure — built to handle real production load.

REST & GraphQL APIs

Clean, well-documented APIs built with Fastify, Express, or AdonisJS. We design for the consumer first — mobile app, web client, or third-party integration.

Real-Time Systems

WebSocket servers, Server-Sent Events, and pg_notify-driven real-time updates. We have built systems delivering live data to thousands of concurrent clients.

Background Jobs & Queues

Async task processing with Bull, BullMQ, or SQS. Scheduled jobs, retry logic, and dead letter queues — reliable background work without the complexity.

PostgreSQL & Database Design

We default to PostgreSQL — with PostGIS for geospatial, pg_notify for real-time, and careful index design from the start. We also work with MongoDB and Redis.

Microservices & Monorepos

From a clean monolith to service-oriented architectures. We know when to split and when to stay together — and we help you avoid premature microservices complexity.

AWS & Azure Deployment

Node.js services deployed to ECS Fargate, Lambda, or Azure Container Apps with full CI/CD. Auto-scaling, health checks, and observability built in from day one.

Built with Node.js

Diagnostic laboratory testing reimagined

Common Questions

What Node.js frameworks do you use?

We use Fastify for high-performance APIs, AdonisJS for full-featured backend applications (similar to Laravel/Rails), and Express for simpler use cases or when inheriting a codebase. We choose based on your use case — not familiarity.

Do you build monoliths or microservices?

It depends on where you are. Most early-stage startups are better served by a well-structured monolith. We help you avoid the premature complexity of microservices and architect for the scale you actually need — with clear boundaries that make future splits straightforward.

Can you integrate with third-party APIs?

Yes — extensively. Stripe, Plaid, Auth0, HubSpot, Twilio, Klaviyo, AWS services, and many more. Third-party integration is a core part of most of our projects.

How do you handle performance and scalability?

We design for the load you will actually face — not theoretical scale. Database indexes, query optimization, caching with Redis or ElastiCache, and horizontal scaling on ECS or Lambda. We benchmark before and after.
