Proof, not promises.

Real benchmarks from production engagements.

  • TypeScript

    End-to-end strict

    No 'any', shared types front + back

  • Real-time

    Production-ready

    WebSockets, SSE, BullMQ

  • Next.js + NestJS

    Default combo

    Or Next.js + Fastify for simpler APIs

What we deliver

The capabilities our Node.js / JavaScript engineers ship.

Production patterns from real engagements — not a stack-marketing checklist.

  • 01

    TypeScript end-to-end

    Strict mode, no implicit any, shared types via monorepo (Turborepo/Nx) or tRPC. The JS pitfalls don't reach production.

  • 02

    Next.js front-end

    App Router, React Server Components, Server Actions. See [Next.js expertise](/expertise/web-development/nextjs) for depth.

  • 03

    NestJS / Fastify / Express APIs

    NestJS for structured large APIs, Fastify for high-throughput, Express for simple services. Typed routing, DI, OpenAPI auto-generation.

  • 04

    Data layer

    Prisma or Drizzle ORM with PostgreSQL/MySQL, Mongoose for MongoDB, Redis for cache/queues.

  • 05

    Real-time

    Socket.io, WebSockets, Server-Sent Events, Pusher. Live dashboards, chat, collaborative editing.

  • 06

    Background jobs

    BullMQ + Redis for queues, Inngest for serverless workflows, cron for scheduling.

Who hires us for Node.js / JavaScript

Where this stack fits best.

We've seen the patterns — match yours against the list to find the closest fit to your situation.

  • B2B SaaS

    Multi-tenant SaaS dashboards, admin tooling, customer portals. Next.js + NestJS is our default combo.

  • Real-time apps

    Live dashboards, chat, collaborative editing, gaming, trading interfaces — where WebSockets and SSE matter.

  • API services

    Typed REST/GraphQL APIs serving multiple front-ends, paired with OpenAPI / GraphQL schema-first design.

  • Marketplaces

    Two-sided marketplaces with payments, matchmaking, ratings, messaging.

  • Monolith decomposition

    Companies breaking monoliths into Node.js services with shared TypeScript types.

How we engage

From brief to production.

Transparent, milestone-driven, with clear owners and timeframes at every stage.

  1. 01Week 1

    Architecture

    Front-end/back-end split, type-sharing strategy, monorepo setup, data layer, deployment plan.

  2. 02Weeks 2–10

    Build

    Two-week cycles, working software each Friday, CI/CD with type-checking enforced.

  3. 03Weeks 10–12

    Hardening

    Performance, security, observability, real testing. Edge-case coverage.

  4. 04Week 13

    Production

    Staged deployment, hypercare, monitoring.

Node.js / JavaScript in depth

Inside our Node.js / JavaScript practice.

The long-form view of how we approach Node.js / JavaScript engagements.

JavaScript / TypeScript as a first-class stack

We treat JavaScript / TypeScript as a first-class production stack — not a scripting language that grew up. Typed end-to-end with TypeScript, React / Next.js on the front, Node.js / NestJS / Fastify / Express on the back, with shared types across the boundary.

What we deliver

  • TypeScript everywhere — strict mode, no 'any', shared types across front-end and back-end
  • Next.js front-end with App Router, RSC, Server Actions
  • NestJS, Fastify or Express API services with typed routing, DI, OpenAPI
  • Real-time — WebSockets, Socket.io, Server-Sent Events for live features
  • Background jobs — BullMQ for queues, Inngest for serverless workflows
  • Testing — Vitest, Playwright, contract tests

Where Node.js fits best

I/O-heavy services (APIs, real-time, streaming), shared-type advantage across full-stack, fast iteration with a single language.

Why Redian for Node.js / JavaScript

What makes our Node.js / JavaScript practice different.

Independent reasons clients pick us over freelancers, agencies and large consultancies.

  • Strict TypeScript

    Strict mode, no 'any' in production code, shared types across front-end and back-end.

  • Modern Node ecosystem

    Latest Node LTS, modern frameworks (Next.js 15, NestJS 10, Fastify 4), modern tooling (Vitest, Turborepo).

  • Production-grade discipline

    Observability, structured logs, tracing, real testing — JS doesn't get a pass on production rigour.

  • Polyglot perspective

    We also do Python, Java, PHP. We pick Node when it fits — not because it's all we sell.

NestJS vs Fastify vs Express?

NestJS for structured larger APIs with DI, decorators and Angular-like architecture. Fastify for high-throughput APIs with less ceremony. Express for simple services or when the team is already there. We pick by fit, not religion.

Should we use Node.js for our backend?

Yes if you have I/O-heavy services, real-time needs, or want full-stack JS with shared types. No if you have CPU-heavy compute (Python or Java better), regulatory environments where Java's libraries dominate, or already-strong PHP/Python teams.

Do you do GraphQL or REST?

Both, with strong views. GraphQL for client-driven front-ends needing flexible queries. REST/OpenAPI for service-to-service APIs and simpler products. tRPC for full-stack TypeScript projects where front-end and back-end ship together.
