Custom application development

We design, build and test web, back-end and data-driven applications for business-critical processes, from the first architecture decision to a release pipeline that ships changes safely every week.

What we do

Scope of work

  • Discovery and architecture

    Requirements, user flows and a technical architecture sized to your scale, budget and existing systems.

  • Web applications

    Responsive, accessible front ends in React, Next.js or Angular with a consistent design system.

  • Back end and APIs

    Services in .NET, Java, Node.js or Python with REST or GraphQL APIs, authentication and audit trails.

  • Data-intensive applications

    Portals, internal tools and dashboards that read from and write to your data platform.

  • Quality assurance

    Automated unit, integration and end-to-end tests, code review and static analysis in every pipeline.

  • Cloud deployment

    Containerised deployment to AWS, Azure, Google Cloud, OVHcloud, Hetzner Cloud, UpCloud or a private cloud with infrastructure as code and monitoring.
