Can your Node.js team work with our existing microservices?

Yes. We regularly build new services that integrate with existing architectures. We start by mapping service dependencies, understanding deployment patterns, and documenting API contracts before writing code.

How do you verify Node.js API performance at scale?

Load testing starts in week 6, not at the end. We use k6 and Artillery to simulate traffic patterns, profile with Node.js diagnostics, and implement caching, connection pooling, and query optimization based on real data.

Do you build serverless Node.js applications?

Yes. We deploy to AWS Lambda, Vercel Functions, and Cloudflare Workers depending on your latency, cost, and cold-start requirements. We have shipped serverless APIs handling 10M+ monthly invocations.

What about database design and migrations?

Database design is part of the architecture phase. We use Prisma for type-safe database access, write migration scripts for every schema change, and implement zero-downtime migration strategies for production databases.

Overview

Why Node.js?

1Raft provides Node.js development teams specializing in high-performance APIs, real-time systems, and event-driven architectures. With experience across Express, NestJS, and serverless platforms, 1Raft engineers have built backend systems processing millions of daily requests for fintech, commerce, and SaaS products.

Node.js is the engine behind most of the products we ship. Our engineers use it to build REST and GraphQL APIs, WebSocket servers, background job processors, and serverless functions. The common thread: systems that handle real production traffic without surprises.

We default to TypeScript and NestJS for new projects. The structure enforces clean architecture patterns that keep codebases maintainable at 50,000+ lines. For lighter services, Express or Fastify with a clear module structure works just as well.

Our Node.js teams have built payment processing systems handling $2M+ daily volume, real-time notification engines delivering 500K+ messages per hour, and API gateways aggregating data from 15+ microservices. We know where Node.js excels and where you need a different tool.

Process

How the engagement works

Week 1

System design and API contracts

Map your data model, define API contracts with OpenAPI specs, and establish the service architecture. If integrating with existing systems, we document every dependency.

Weeks 2-3

Core infrastructure

Database schema, authentication layer, CI/CD pipeline, and the first working API endpoints. Deployed to a staging environment you can test against.

Weeks 4-9

Feature development

Two-week sprints building business logic, integrations, and real-time features. Load testing starts in week 6 to validate performance targets early.

Weeks 10-12

Production hardening

Security audit, load testing at 3x expected traffic, monitoring dashboards, runbooks, and infrastructure-as-code handoff. Your ops team gets everything they need.

Use Cases

Real-world Node.js projects

Payment processing API for a fintech startup

Built a multi-currency payment API with Node.js and NestJS. Integrated Stripe, Adyen, and local payment providers across 12 countries. Real-time webhook processing and idempotent retry logic. → Processing $2.1M daily volume with 99.99% success rate. Payment reconciliation time dropped from 4 hours to 12 minutes.

Real-time notification engine for a SaaS platform

Designed an event-driven notification system using Node.js, BullMQ, and WebSockets. Push notifications, in-app alerts, email, and SMS through a unified API. → Delivering 500K+ notifications per hour with sub-second latency. Notification delivery rate improved from 87% to 99.2%.

API gateway for a hospitality platform

Consolidated 15 microservices behind a single Node.js API gateway. Rate limiting, request transformation, caching, and unified error handling. → Average API response time dropped from 340ms to 89ms. Frontend team development velocity increased 45% with consistent API contracts.
