[ Node.js Services ]
Backend Work We Take On
From one microservice to the whole server side of a product, written in typed, tested Node.js.
REST and GraphQL APIs
APIs for web and mobile clients, with clear contracts, versioning and documentation your frontend team can rely on.
Scope:
- API development with OpenAPI specs
- GraphQL schemas and resolvers
- Authentication with OAuth and JWT
- Rate limiting and request validation
NestJS Applications
A structured framework for larger backends, where modules, dependency injection and conventions keep a growing team consistent.
Scope:
- NestJS modules and service layers
- TypeORM and Prisma data access
- Unit and integration tests
- Role-based access control
Microservices and Event Processing
Services that talk through queues and events, for systems where one process should not bring down another.
Scope:
- Message queues with RabbitMQ or Kafka
- Background jobs and schedulers
- Webhooks from payment and CRM providers
- Tracing across services
Real-Time Features
Live updates for dashboards, chat, notifications and collaborative tools.
Scope:
- WebSocket and Socket.IO servers
- Presence and typing indicators
- Redis pub/sub for horizontal scaling
- Push notification delivery
Third-Party Integrations
Connections to the systems a business already runs on, so data moves without manual exports.
Scope:
- Stripe and other payment gateways
- CRM and ERP sync
- Accounting and invoicing APIs
- LLM provider APIs for AI features
Node.js Upgrades and Performance
For older codebases on outdated Node versions, plain JavaScript or a slow monolith.
Scope:
- Audits of existing Node.js projects
- Migration from JavaScript to TypeScript
- Memory leak and latency profiling
- Splitting a monolith into services
[ How We Begin ]
Three Ways Into a Node.js Project
The order we usually follow when a backend team or product owner first contacts us.
2. Written Proposal
You receive a plan with the team size, the first milestones and either a project budget cap or a monthly rate for dedicated engineers.
3. First Sprint in Your Repository
After onboarding, the engineers open their first pull requests in your codebase and present the result at the end of the two-week sprint.
[ Why Akveo ]
What You Get With Our Polish Node.js Team
Experienced TypeScript engineers, EU working hours, and clear rules for code, data and cost.
Based in Warsaw
The team sits at Domaniewska 17/19 in Warsaw. Architecture workshops can happen there or over a video call.
TypeScript Everywhere
Typed code on the server and in shared packages catches mistakes before they reach production and makes handover easier.
Overlap With Your Workday
CET hours mean daily standups, code reviews and incident calls happen while your own team is online.
EU Data Handling
We work under a data processing agreement and keep databases and logs in the regions your compliance team approves.
Monthly Billing for Teams
Dedicated engineers are billed monthly, so you can add or remove capacity as the roadmap changes.
Code Stays Yours
Every commit lands in your repositories, and all code and documentation belong to your company.

[ Case Studies ]
Node.js Backends in Production
Platforms where our engineers built or extended the Node.js and NestJS layer.
HealthcareNestJS
Low-Code Builder for a Health Insurance Platform
85% less time spent on app configuration
A US company building customer portals for health insurers relied on error-prone JSON configuration. We built a visual builder on a NestJS and Node.js backend, designed for multi-tenant deployments, which also cut configuration-related bugs by 60%.
FintechTeam Extension
Billing Automation for a Portuguese Neobank
3x faster billing cycle
A business finance platform used by more than 1,500 Portuguese companies needed to automate tax compliance and invoicing. Our engineers joined the client's team, worked on the Node.js and NestJS services, and helped match transactions to invoices automatically.
HealthcareMobile Backend
Pet Health App With a NestJS Backend
From idea to live app in 5 months
Sploot Vets wanted pet owners to manage appointments, medications and messages with their vet from one app. We built the mobile app and its Node.js backend, including automated medication reminders, and reached 500+ downloads at launch.
