Backend & API

The invisible engine holding your application up

We design and build backends and APIs in Alghero and remotely: solid architectures with Node.js, Python and PostgreSQL that sustain growth without falling over. From a simple API to full microservice architectures.

01What we offer

Solid foundations for every product

Clean APIs, well-modelled data and security from day one: the part you don’t see, holding up everything else.

REST & GraphQL APIs

Clean, documented interfaces for apps, sites and services to talk to each other.

Databases

Design and optimization of relational and NoSQL databases: PostgreSQL, MongoDB, Redis.

Security

Authentication, authorization, encryption and protection from the most common vulnerabilities.

Microservices

Modular architectures that separate responsibilities and evolve without stopping everything.

Integrations

Payments, email, SMS, AI services, ERPs: we connect your software to the outside world.

Performance

Optimized queries, caching and load balancing for fast responses under load.

02Stack

The stack, in black and white

Proven technologies, chosen for the case rather than out of habit.

APIs
REST and GraphQL, documented with OpenAPI/Swagger
Runtime
Node.js, Python
Databases
PostgreSQL, MongoDB, Redis

03Our process

Designed first, written second

API contracts and data schema are defined before the code: fewer surprises, simpler integrations.

  3. Development

    03

    Implementation with automated tests and code review

  4. Security

    04

A backend with authentication, database and documented APIs starts at € 2,000; a system integration at € 1,200; a full architecture redesign at € 5,000. Cost depends on entities and integrations: after a free call we send a detailed quote.

For most projects REST is the simplest and most universal choice. GraphQL pays off when the frontend needs very flexible data from multiple sources (complex dashboards, apps with many screen types). We recommend based on the case, not habit.

Yes, it is the most common case. We analyze the existing code, intervene on critical points and add new features without stopping the service, with progressive and reversible releases.

Authentication and row-level permissions, encryption in transit and at rest, protection from the most common vulnerabilities (injection, XSS, privilege abuse), periodic audits. We follow OWASP guidelines and handle backups too.

We design for scalability from day one: caching, optimized queries and infrastructure that grows with traffic. Before launch we run load tests to verify real limits, not theoretical ones.

Always: every API we deliver comes with complete, up-to-date documentation (OpenAPI/Swagger) with request and response examples. It serves you, your team and anyone working on the project in the future.
