Technology

Technology as a discipline, not as a one-off service.

Software, cloud and security are part of the same system. These are the capabilities that support Castteli's work.

Technology

Engineering, architecture and product.

  • 01

    Software engineering

    Typed, tested web applications and backend systems, designed to evolve without a rewrite.

  • 02

    Systems architecture

    Clear boundaries between domains, explicit contracts and recorded decisions.

  • 03

    APIs and integrations

    Versioned contracts, validated at the edge, ready to connect systems.

  • 04

    Digital products

    From problem to interface: product, design and engineering in the same flow.

Cloud

Infrastructure that explains itself.

  • 01

    Infrastructure and delivery

    Separate environments, automated deployment and declarative configuration.

  • 02

    Observability

    Logs, metrics and traces designed before the first incident.

Security

Security as architecture.

  • 01

    Security by design

    Authentication, authorization and validation treated as architecture, not as a fix.

  • 02

    Supply chain

    Audited dependencies, secrets kept out of the code and a pipeline that fails before publishing.

The capabilities describe how Castteli works. No certification, partnership or client is implied on this page.
