Node.js development services
Node.js development services for REST and GraphQL APIs, e-commerce and SaaS back ends, payment and fintech integrations, real-time chat, streaming and collaboration features, background workers and serverless functions in TypeScript, with dedicated Node.js developers for your team or a Node.js project delivered end to end.
What we build with Node.js
REST and GraphQL APIs
Typed APIs in TypeScript on NestJS, Fastify or Express, with request validation by Zod at the edge and an OpenAPI or GraphQL schema the front end is generated from.
Full-stack TypeScript applications
Next.js, Angular or React on the front, Node.js behind it and Prisma or Drizzle over PostgreSQL, with shared types so the contract between them cannot drift.
Headless commerce back ends
Cart, checkout, pricing and order services behind headless storefronts, built on Medusa or commercetools or connected to Shopify, with stock and payment events handled through signed webhooks.
SaaS product back ends
Multi-tenant back ends with tenant isolation enforced by PostgreSQL row-level security, subscriptions and invoices through Stripe Billing, and role checks on every route.
Payments and fintech integrations
Stripe, Adyen and open banking APIs, CRMs and marketplaces connected through webhooks with signatures verified, every call idempotent and amounts held in minor units, never in floating point.
Real-time and collaboration features
WebSocket, Socket.IO and server-sent-event services for chat, notifications, live dashboards and shared editing with Yjs, scaled across instances through Redis, with back-pressure and reconnection handled rather than hoped for.
Media upload, streaming and calls
Resumable uploads, FFmpeg transcoding queues and HLS delivery through a CDN with signed URLs, and WebRTC media servers on mediasoup or LiveKit, with the signalling around them, for video calls and live rooms.
Background workers and event queues
Jobs on BullMQ, RabbitMQ, Kafka or cloud queues with retries, dead-lettering and alerts, so a failed job is visible instead of silently dropped.
Serverless and edge functions
AWS Lambda, Azure Functions, Cloud Run functions or Cloudflare Workers in TypeScript for spiky workloads, where paying per request costs less than a server waiting for traffic.
Hire Node.js developers
Dedicated Node.js developers
Node.js developers who join your team full time, work in your repositories, tracker and meetings, and report to your lead. You interview them; we carry the Ukrainian contract, payroll, invoicing and leave.
Node.js project delivery
A team that takes the Node.js project from scope to release: estimate, build, tests and deployment, with a technical lead on our side who owns the plan and the quality.
Node.js support and take-overs
An existing Node.js system taken over from another team or kept running: a read-only review and a written list of risks first, then fixes and new features in order of impact.
The dedicated team page explains how specialists join your team, and the outsourcing page covers project delivery, take-overs and how we charge.

How we work on Node.js
TypeScript in strict mode, never plain JavaScript for new code. Input is validated where it enters the service, secrets come from a vault rather than a file, dependencies stay current with advisories treated as unconditional upgrades, and every query and command is parameterised.
Developers work in your repositories, your tracker and your process. The Ukrainian contract, payroll, invoicing and leave stay with us, and everything they write is assigned to you.

Questions about Node.js development
Which industries do your Node.js developers work in?
E-commerce and marketplaces (storefront APIs, checkout and order services), SaaS and enterprise software (multi-tenant back ends and billing), fintech (payment integrations, wallets and customer onboarding), media and consumer apps (streaming, chat and feeds), and ad tech, healthcare, education and logistics, where Node.js runs tracking, booking and live dashboards.
Which Node.js frameworks do you use?
NestJS for larger services that benefit from its structure, Fastify or Express for smaller ones, and Next.js where the backend serves a React front end, with Prisma or Drizzle for data. All in TypeScript, on current LTS releases of Node.js.
Can you take over an existing Node.js backend?
Yes. It starts with a read-only review of dependency advisories, untyped JavaScript, unhandled promise rejections and test coverage, written up as a list of risks. The code then moves to TypeScript and a current Node.js LTS release file by file, each step released on its own.
How quickly can Node.js developers start?
When the right Node.js developer is available, the start is gated only by your interview and the NDA and IP assignment. Otherwise we run a search, which typically produces candidate profiles within two to three weeks, and nobody starts until you have said yes.
How do we hire Node.js developers through BigTree108?
Tell us the work, the seniority and the hours you need. We propose one or two people with their profiles, you interview them the way you would interview your own hire, and you sign one agreement with BIG TREE 108 LLC and receive one invoice a month.
Who owns the work they produce?
You do. Every specialist has a signed contract with BigTree108 that assigns all work product to the company, and our agreement with you assigns it onward. Code, designs and documents are delivered into your own repositories and tools, not kept where only we can change them.
Need a Node.js backend?
Tell us what the service has to do and what it sits beside. You get an answer within one business day: a plan or candidate profiles.
