Backend for web and mobile applications
Services, business logic, user and data management for web applications, mobile apps and back-offices.
Custom software development
Node.js backend and custom API development
We build the backend, custom APIs and middleware that connect your applications with your company systems. Node.js is our main technology, and we build secure, scalable services ready to integrate with ERP, CRM and third-party platforms.
Data and processes spread across systems
Web and mobile applications depend on a reliable backend, and business processes are often spread across ERP, CRM and tools that don't talk to each other. We design and build the pieces that connect those systems, with well-defined APIs, security and room to grow.
Backend with Node.js
Node.js is the technology we use for most of our backends: services and APIs that handle many concurrent requests, integrate well with cloud services and share a language with the front-end, which simplifies maintenance.
We don't impose a stack: if your organisation works with other languages or frameworks, we adapt to them and to your infrastructure so your team can maintain the solution.
What we build
We adapt to your organisation's languages, frameworks and infrastructure.
Custom API development
We design and build REST APIs documented with OpenAPI 3.0 and GraphQL APIs, secure and ready for internal use or to offer services to customers and partners.
Middleware and systems integration
We connect applications with ERP, CRM and corporate systems: data synchronisation, process orchestration, messaging with Amazon SQS and MQTT, and integration with third-party services.
Authentication and security
We integrate corporate authentication, access control and permissions, and apply security best practices to the design of services and APIs.
Systems integration
Much of a backend's value lies in how it connects the systems a company already uses. We integrate ERP, CRM and corporate applications through APIs, connectors and middleware, and use queues and events, such as Amazon SQS or MQTT, when processes need to be decoupled or work in real time.
That is how the middleware connecting PreZero's logistics platform with its ERP assigns routes, trucks and drivers, and how the serverless middleware links Grupo Noria's application with its internal systems.
Architectures built to grow
We choose the architecture to fit the problem, from traditional services to serverless cloud solutions. When the project needs it, we design and deploy the backend on AWS.

Five Flames has held ISO/IEC 27001 certification since 2020. Our information security management system supports the development of services, APIs and integrations.
How we work
Analyse
We review systems, data and the integrations required.
Design APIs and architecture
We define API contracts, data model and security.
Build and integrate
We build the services and connect them with existing systems.
Test
We validate behaviour, integrations and performance before going live.
Go live
We support the deployment and document the APIs for your team.
Backend and API development FAQ
Why do you build backends with Node.js?
Node.js is efficient for services and APIs with many concurrent requests, integrates well with cloud services such as AWS and shares a language with the front-end. It is our main technology, although we adapt to each organisation's stack.
What kind of APIs do you build?
We build REST APIs documented with OpenAPI 3.0 and GraphQL APIs, for internal use or to offer services to customers and partners, with authentication and access control.
Can you integrate our ERP or CRM with other applications?
Yes. We analyse which data and processes need to be connected and build the integration through APIs, connectors or middleware, with data synchronisation and messaging when needed. That is what we do, for example, with PreZero's ERP.
Where is the backend deployed?
It depends on the project. We deploy both on the client's infrastructure and in the cloud; when the project requires it, we design the backend on AWS with serverless services such as AWS Lambda and Amazon SQS.
Can you evolve an existing backend?
Yes. We review the current code and architecture, propose improvements and evolve it in phases, or integrate it with new services without disrupting operations.
Which systems do you need to connect?
Tell us which applications and systems you use. We will help you define the architecture and the integrations.
