Backend development, APIs and business integrations

We build solid backends, secure APIs and custom integrations to connect mobile apps, web dashboards and internal systems in one reliable platform.

Connected platform

Mobile apps Secure API Admin dashboard External systems

Reliability logs, roles, permissions and clear rules

The decision before the project

Fit: Internal and external systems that need to connect through clear contracts.
Expected outcome: Architecture and data model, including relevant roles, permissions and rules.
Primary risk: A project that cannot define ownership of its core data and rules.

Who this service is for

A good fit when

Apps and dashboards that need to share data, rules and states consistently.
Operations that require authentication, roles, permissions, logs or automatic tasks.
Internal and external systems that need to connect through clear contracts.
Companies in Catalonia; projects elsewhere in Spain and remote collaboration can also be considered.

Not a good fit when

A static page with no logic, data or integrations.
A project that cannot define ownership of its core data and rules.
An integration without authorised access or minimum documentation for the external system.

Problems it can help solve

Scattered data and rules

Centralise validations and contracts so apps and dashboards use the same criteria.

Errors without traceability

Add logs, states and task handling to understand failures and incidents.

Fragile integrations

Set boundaries for authentication, errors and responsibilities across internal and external systems.

Possible deliverables

Depending on the agreed scope, the service may deliver:

Architecture and data model, including relevant roles, permissions and rules.
APIs with contracts, validations and authentication included in scope.
Documented integrations with apps, dashboards or external systems.
Logs, jobs, notifications and operating criteria based on agreed needs.

How the work is approached

Map data and responsibilities

Identify which system originates each item of data, who can change it and which rules apply.
Define contracts and security

Specify endpoints, authentication, roles, permissions, validations and errors.
Implement by capability

Build APIs, rules and integrations in reviewable blocks.
Test the operation

Validate permissions, consistency, external failures, jobs, logs and critical journeys.

Integrations and technologies

The technical scope may use components already described on the service page:

Laravel for backend services and endpoints.
APIs for mobile apps and web dashboards.
Authentication, roles, permissions and validations.
Payments, notifications, jobs and external systems.
Server logs and traceability.
Rates, zone pricing and business rules.

Common risks and decisions

Which system is the source of truth for each shared item of data.
Where to apply rules and validations to prevent different client behaviour.
How to handle failures, retries and duplicates in integrations and jobs.
What to record in logs without exposing unnecessary data.

Ways the work can be scoped

Architecture analysis

Review data, contracts, risks and dependencies before implementation.

Backend development

Build the APIs, rules, permissions and tasks included in scope.

Integration with other systems

Connect apps, dashboards or external systems within the agreed scope.

FAQ

Questions about backend and integrations

What matters before building the technical foundation of a platform.

What does a robust backend include?

Secure APIs, authentication, roles, permissions, validations, logs, notifications, dashboards and integration with apps or external systems.

Can you integrate mobile apps with web dashboards?

Yes. We create APIs and integrations to connect mobile apps, web dashboards, internal systems and external services.

Do you work with payments, rates or complex rules?

Yes. We can implement payments, zone pricing, rates, validations, jobs, logs and specific business rules.

Initial assessment

Do you need to connect apps, dashboards and internal systems?

We review flows, data, security, integrations and technical risks to define a reliable backend.
