Microservices Architecture
Domain-driven service decomposition with NestJS, gRPC and message-queue communication, distributed tracing via OpenTelemetry, and independent CI/CD per service.
Event-driven Node.js engineers for real-time platforms, microservices, and APIs that scale to millions of users.
When your product needs real-time data, high concurrency, and a single language across the stack, Node.js is the answer — and Devlex Infotech's Node.js developers are the team that makes it deliver. They architect non-blocking services with NestJS and Express, stream events through Kafka and Redis, and design TypeScript codebases that stay readable as your engineering team grows around them.
Our Node.js practice has built trading dashboards pushing live ticks to 100,000+ concurrent WebSocket connections, logistics APIs processing 5 million requests a day, and chat infrastructure for healthcare platforms with GDPR and HIPAA obligations. Hire from $15/hour or $2,400/month full-time, onboard in 24-48 hours, and scale with the team behind 25+ delivered projects.
Domain-driven service decomposition with NestJS, gRPC and message-queue communication, distributed tracing via OpenTelemetry, and independent CI/CD per service.
Socket.IO and native WebSocket layers with Redis pub/sub fan-out, presence systems, and backpressure handling proven at 100,000+ concurrent connections.
TypeScript-first REST and GraphQL APIs with Zod validation, rate limiting, API-key and OAuth 2.0 auth, and p99 latencies kept under 100ms at load.
AWS Lambda, ECS Fargate, and Cloudflare Workers deployments with infrastructure as code (Terraform, CDK) and cold-start optimization.
Kafka and Kinesis ingestion pipelines for analytics, IoT telemetry, and audit trails — exactly-once processing with consumer-group scaling.
Incremental migration of PHP, Java, and .NET monolith endpoints to Node.js microservices behind an API gateway, with zero downtime and side-by-side benchmarks.
Scale up, scale down, or switch models anytime — no lock-in, no recruitment fees.
A developer who works exclusively on your project.
Ideal for ongoing improvements and smaller scopes.
Pay only for the hours you actually use.
Quoted before work starts · no recruitment fees · dedicated full-time from $2,400/month · scoped tasks from $12
Every new Node.js codebase we ship is strict-mode TypeScript with ESLint, Prettier, and 80%+ coverage — JavaScript-only legacy is something we fix, not create.
Engagements start with a documented architecture decision record, capacity model, and API contract — so scaling problems are designed out, not patched later.
Vetted Node.js engineers from our 60+ expert bench can be interviewed within 24 hours and merged into your team within 48.
Most of our Node.js developers also work in React or Vue, so a single hire can own features end to end when your team is lean.
Docker, Kubernetes, GitHub Actions, and observability with Grafana and Datadog come standard — your developer ships and operates the service.
Five years in business, clients in 5+ countries, and out-of-hours support available under a separate agreement for production systems we build.
From first call to onboarded developer in less than a week.
Tell us the skills, experience level, and team size you need — we respond within 24 hours.
We share hand-picked, pre-vetted developer profiles within 24–48 hours.
Interview candidates over video calls, review code samples, and run a paid trial task if you like.
Sign the NDA and agreement — your developers start within days, with full IP protection.
The frameworks, platforms, and tools our node.js developers work with every day.
Terms that go into every agreement we sign. See all client commitments.
Every job gets a scope and a number in writing first — a fixed price for defined work, or an hourly rate with a capped estimate. If scope changes, we re-quote before we build, not after.
Source code, designs, and data are yours. We work in your repository where possible, hand over full documentation, and transfer everything at the end. No license fees, no hostage situations.
We sign your NDA — or send ours — before the first technical conversation. Your idea, your data, and your customer information stay confidential during and after the engagement.
Everything you need to know before starting your project. Still have questions? Talk to our team.
From $15/hour, or a dedicated full-time developer from $2,400/month at 160 hours. Choose full-time, part-time (80 hrs/mo), or hourly (40-hour minimum) — and switch models with 30 days notice. Final quotes depend on seniority and are confirmed after a free scoping call.
Onboarding takes 24-48 hours. You will see shortlisted profiles within one business day, run your own technical interviews, and have the selected engineer in your standups and codebase within two working days.
We execute a mutual NDA before any product discussion. Developers sign individual confidentiality and IP-assignment agreements, access is provisioned on least-privilege principles, and everything they produce is your property.
Yes. We guarantee at least 4 hours of daily overlap with your time zone and offer full-shift alignment for US East Coast, UK, and EU clients. Production systems additionally get 24/7 support escalation.
We offer a no-cost replacement, normally within a week, including internal knowledge transfer so your delivery does not stall. During the initial trial period you can exit with no obligation beyond hours already worked.
Share your architecture or just your idea — we will respond with matched Node.js profiles and a technical plan within 24 hours.
