Node.js backends and AI integrations, built and deployed into production.

Gaper builds Node.js backends and the AI integrations that run on them, then deploys them into your stack. We ship the APIs, services, and supervised agents that production workloads depend on, wired into your data and auth.

In one sentence

Node.js development at Gaper means production backends, APIs, and AI integrations built on Node.js and TypeScript, then deployed into your cloud on your data and auth. We deliver the services, evals, and runbook, and your team owns the code.

Why this matters

A working Node prototype is one thing. A service that holds up under real traffic, talks to your existing systems, and runs an AI feature safely in production is the part that decides whether the project ships.

Production filter
  • Does it touch real systems?
  • Can the outcome be measured?
  • Where does human approval stay?
  • Who owns it after launch?

Map your first production agent
How we work

From strategy to production, owned by your team.

  1. 01

    Map the workflow

    We start from the documents, SOPs, portals, inboxes, and spreadsheets your team already uses, then turn the repeatable path into an agent workflow map.

  2. 02

    Build the supervised agent

    We build on OpenAI, Claude, Gemini, or the right model for the job, with evals, guardrails, citations, and human approval gates where risk matters.

  3. 03

    Connect the stack

    The agent gets the data layer, APIs, MCP tools, auth, and write-backs it needs to finish work inside your systems, not beside them.

  4. 04

    Sandbox, verify, go live

    We launch in a sandbox, verify every run, then move into supervised production with traces, rollback, and an owner.

What we build

Agents wired into the systems you already run.

Node.js APIs & services

REST and GraphQL backends in Node.js and TypeScript, built for the throughput, latency, and edge cases real traffic brings.

AI integrations

LLM features wired into your Node services on OpenAI, Claude, or Gemini, with streaming, retries, and graceful fallbacks.

Supervised agents on Node

Goal-driven agents running in your Node stack that call tools, hit your APIs, and gate risky actions behind human approval.

Real-time & streaming

WebSocket, SSE, and event-driven services that stream model output and live data to users without buffering the whole response.

Data & integration layer

Connectors to Postgres, your queue, and third-party APIs via MCP, so the backend finishes work inside your systems, not beside them.

Observability & evals

Tracing, cost and quality dashboards, and automated evals on AI paths, so you can see exactly what every run did and why.

Built into production, not bolted on

We deploy the Node services where your data lives: your cloud, your auth, your controls. The backend inherits your security posture instead of widening your attack surface.

  • Runs in your environment or ours
  • SSO, RBAC, and audit logging
  • No data retention you didn't ask for

You own the code, and the runbook

A forward-deployed team works alongside yours and hands over a clean, documented Node.js codebase you fully control. No black box, no lock-in, nothing trapped outside your stack.

  • Typed, tested, documented services
  • Knowledge transfer built into delivery
  • Extend and ship it without us

AI features that survive real traffic

Most LLM integrations work in a demo and fall apart under load. We design for that gap: evals before users, retries and fallbacks on every model call, and rate limits and timeouts that keep the service up.

  • Evals gate every release
  • Fallback and escalation paths
  • Load-tested before go-live

FAQ

Questions buyers ask us.

What does Gaper build with Node.js?+
Production Node.js and TypeScript backends: REST and GraphQL APIs, real-time and streaming services, and the AI integrations that run on them. We build the service end to end and deploy it into your stack, then hand over the code, evals, and runbook.
How do you deploy a Node backend into our environment?+
We deploy inside your cloud on your data and auth, integrated through your APIs and MCP. The service inherits your security posture with SSO, RBAC, and audit logging, so data stays inside your boundary.
Who owns the code after launch?+
You do. We deliver a clean, documented, typed codebase plus evals and a runbook. Your team can extend and ship it without us, or we can run it under an SLA with observability and ongoing improvement.
Which AI models can you integrate?+
We're model-agnostic: OpenAI, Claude, Gemini, or open models, chosen per task. The Node integration layer handles streaming, retries, fallbacks, and cost tracking regardless of which model is behind it.
