Sound familiar?
- Hiring a senior Node.js developer full-time is taking months.
- Your Node.js codebase has grown messy and every change breaks something else.
- Offshore hand-offs and time-zone gaps turn one-day fixes into week-long threads.
- You need someone senior enough to make decisions, not just close tickets.
What our Node.js engineers build
APIs & microservices
Express, Fastify, and NestJS services that stay fast under load.
Integrations
Payments, CRMs, and third-party APIs connected reliably with retries and alerts.

Common questions
Will this turn into a sales pitch?
No. The call is about your project: what needs building, what's stuck, and whether we have the right engineers. If we're not a fit, we'll say so.
What do I get for free?
A project plan, roadmap, cost estimate and ROI estimate within 48 hours of your project call. Your first 5 development hours are free, too. We agree the scope and any paid work with you before proceeding.
Do I need a spec or brief?
No. Tell us the problem in plain words and we'll help shape the scope with you.
Are the engineers really in the U.S.?
Yes. Every engineer lives and works in the United States. No offshore hand-offs, and that's in the contract.
What our clients say
"NextGen scaled us from 2 to 7 dedicated engineers in under a quarter. Enterprise-grade capacity, zero agency drag."
"Their R&D tax credit workflow platform paid for itself in the first filing season."
"AI-native from day one. Our IRS transcript pipeline runs 24/7 without a human in the loop."
"Property tax appeals used to take weeks. Their comp analysis tooling turned it into hours."
"The AI intake agent handles our tier-1 patient calls with a hand-off cleaner than our old call center."
"POS, inventory, ordering — all unified. We finally have one source of truth across every location."
"The procurement platform paid for itself in the first quarter of use."
"They shipped our matching engine in 6 weeks. Our old team would've taken 6 months."
"Enterprise-grade delivery without the enterprise-agency price tag."
"Their team plugged into our sprint on day one. Zero ramp time."

Hire US-based Node.js developers to build APIs, maintain TypeScript services, and troubleshoot background workers. Whether your stack uses Express 5, Fastify, or NestJS, the work often centers on validation, dependency maintenance, database access, and predictable failure handling. A Node.js 24 LTS upgrade also calls for checking native modules, ESM and CommonJS boundaries, test tooling, and production behavior rather than only changing a container tag.
NextGen Coding Company provides senior engineers based entirely in the US, with no offshore subcontracting. They follow your working hours and participate in your standups, so API design and incident follow-up stay within your team's routine. Most teams interview matched engineers within a week of the first call. Bring your service map, runtime versions, and backlog to a 15-minute call to discuss the right match.
Frequently asked questions
- Should we hire a Node.js developer with Express, Fastify, or NestJS experience?
- Match framework experience to the codebase and the decisions ahead. Express projects often require familiarity with middleware conventions and existing custom structure. Fastify emphasizes schemas and plugins, while NestJS uses modules and dependency injection. Strong candidates should also explain HTTP behavior, TypeScript boundaries, database transactions, and testing beyond the framework they know best.
- Can a Node.js developer upgrade an older application to Node.js 24 LTS?
- Yes, with a compatibility review before rollout. Inventory dependencies, native addons, module formats, and build images; then run tests on Node.js 24 LTS in CI. Check runtime-sensitive behavior such as TLS connections and stream handling. Deploy through a staged environment with observable errors and latency, and keep a tested rollback path.
- How do Node.js developers diagnose high CPU usage or event-loop delays?
- They should distinguish CPU-bound JavaScript from slow external dependencies and memory pressure. Node.js CPU profiles, heap snapshots, and event-loop delay measurements help identify the cause. OpenTelemetry traces can expose database or network bottlenecks. Depending on the evidence, fixes might involve bounded concurrency, worker threads, query changes, or moving heavy computation into separate jobs.
- What makes a Node.js background job system reliable?
- A reliable worker needs explicit retry rules, idempotent handlers, bounded concurrency, and a way to inspect failed jobs. With BullMQ and Redis, discuss persistence and what happens when a worker exits mid-task. Graceful shutdown, timeout handling, and duplicate-delivery tests matter because queues do not remove the need for application-level correctness.
- How will a contract Node.js developer work with our existing engineering team?
- Our engineers work your hours and attend your standups rather than operating through an offshore handoff. Before code access, we sign an NDA and full IP assignment. For onboarding, prepare local setup instructions, API contracts, test commands, and service ownership notes. If the match does not work, we provide a replacement with a proper hand-over.
- Are your developers really based in the US?
- Yes. Every engineer lives and works in the United States. No offshore subcontracting and no hand-offs to another team. That's written into the contract.
- How fast can someone start?
- Most teams interview matched engineers within a week of the first call. Start dates depend on your interview process.
