Design
Domain boundaries, interface contracts and architecture defined with your technical and business teams.
Technology · Node.js
Node.js, for the services that connect your systems.
We design, develop, integrate and evolve Node.js services: internal APIs, exchange gateways and event-driven processing, connected to what already exists.
What we do
Design, develop, integrate, evolve.
We work across the full life of the application, from initial framing to the changes that follow the release.
Development
Versioned code, automated tests, code reviews and continuous integration across separate environments.
Integration
Connection to the services, data and applications already in place, through documented interfaces.
Evolution
Upgrades, version bumps and new capabilities planned without interrupting the service.
Your concerns
The questions an organization asks before choosing.
- Does Node.js hold up under load?
- The non-blocking model suits services that spend their time waiting on other systems. For intensive computation, separate processes are needed: that is an architectural constraint, not a blocking limit.
- How do you control dependencies?
- By keeping the number of packages low, locking versions and monitoring known vulnerabilities. The ecosystem is vast and fast-moving; without that discipline, the risk surface grows on its own.
- What is the benefit of one language on both sides?
- Types, validations and utilities are shared between the service and the interface, which removes an entire class of mismatches. The benefit is real when one team owns both sides.
In practice
Services whose behaviour is known.
An exchange service is judged on how it behaves when something goes wrong, not on how it runs in the nominal case.
Contracts
Interfaces are described and validated, on the way in and on the way out.
Processing
Long tasks go through a queue, with retries and explicit limits.
Observability
Structured logs and metrics make it possible to know where an exchange stopped.
Resilience
Timeouts, retries and circuit breakers defined for each system called.
What we decide for every exchange
- Timeout
- After how long the call is considered lost.
- Retry
- How many attempts, at what pace, and up to what point.
- Idempotency
- What guarantees a replay does not create a duplicate.
- Alerting
- Who is notified, and above which threshold.
Integrations
An application connected to what you already use.
We start from your existing systems and the interfaces they expose. The exact scope is defined during framing: it depends on each system, not on the technology alone.
Data
- Relational databases
- Warehouses and reporting
- Message queues
- Caches and indexes
Services
- Internal APIs
- Third-party services
- Authentication
- Scheduled jobs
Business applications
- CRM
- ERP
- Finance tools
- Customer service tools
Runtime and quality
- Continuous integration
- Logging
- Monitoring
- Automated tests
The right fit?
What tips the decision towards Node.js.
Node.js excels at exchange services and real time. It demands rigour on dependencies and operations.
Decision criteria
- Exchange servicesMany inputs and outputs to other systems, little heavy computation.
- Real timeNotifications, continuous updates or maintained connections.
- Shared languageOne team owning the service and the interface, with common types.
- Fast startupA lightweight execution model suited to frequent deployments.
Counterparts to accept
- Intensive computationIt must be moved out of the main process, or it blocks the service.
- DependenciesThe ecosystem is vast: every added package needs following.
- Release paceSupport cycles require regular upgrades.
- Error disciplineAn uncaught error can stop the process; that is designed for from the start.
If the analysis shows another foundation serves your need better, we say so and point you to the right option.
Operations
What keeps the platform steady after launch.
Operations are not a contract separate from the project: they are prepared during design and continue at the pace you choose.
Environments
Separate development, staging and production, with the same deployment path every time.
Updates
Dependencies and versions tracked and tested before they are applied.
Security
Access management, logging and fixes applied according to their severity.
Backups and recovery
Verified backups and a documented restore procedure.
Monitoring
Availability, errors and response times watched, with a regular review.
Handover
Documentation and code handed to your organization, with no imposed dependency.
Use cases
What it actually looks like.
Three contexts where this approach changes daily life for teams. The interfaces shown are mockups made by our team to illustrate the point, not client projects.
An exchange point between systems
Normalised flows, logged and retried on failure.
A service shared across applications
A stable contract exposed to the products that depend on it.
Updates without reloading
Information pushed to the interfaces waiting for it.
