Architecture for complex software.

We design and build the systems behind your business: platforms, internal tools and the connections between them. From the data model to the interface your team uses every day.

Software architecture

01

Give complexity a clear structure.

When a product starts, grows or becomes difficult to change, its architecture matters. We map the business, its rules and its data to define how each part of the system should work and connect.

What we work on

  • Domain and data modelling
  • Module boundaries and responsibilities
  • API contracts and access permissions
  • Technical review and evolution or migration plans

Custom software

02

Platforms built around how you operate.

When off-the-shelf tools no longer fit, we build software around your workflows. We connect business rules, data and interfaces in platforms your team can use and continue to develop.

What we work on

  • Custom platforms and internal tools
  • Business rules and operational workflows
  • User roles, permissions and administration
  • APIs, data access and product interfaces

In practice

Catalònia OS · In development

We are building the club’s own digital platform: a multilingual website, news, content and connections with its management systems. A foundation for future internal operations and a members’ app.

Integrations & automation

03

Connect the systems your team depends on.

Information often lives across several tools. We define how it moves between them and automate repetitive steps, with clear rules for validation, errors and tasks that still need a person.

What we work on

  • API integrations and webhooks
  • Data mapping and synchronisation
  • Process automation and approval steps
  • Validation, retries and execution records
  • AI agents connected to tools and data

Technical foundations, page structure and content that help people find you.

Tell us what your system needs to solve.

A new platform, a product that needs to evolve or tools that should work together. We can start from your existing system or help define the first version.
