Connect the systems your business depends on.

Your digital product rarely works alone. We connect the services, data and infrastructure behind it so your systems can work together.

Integration & Infrastructure overview

The technical systems that connect your product and business tools.

  • APIs
  • Payments
  • Databases
  • Cloud
  • Authentication
  • Third-party integrations
  • Deployment

What we connect

  • Payment Gateways: Payment providers for transactions and payment workflows.
  • Third-Party APIs: Connect external services to your website, application or software.
  • Business Tools: Connect tools your business already uses where integrations are required.
  • Databases: Design and connect structured data systems.
  • Cloud Services: Hosting, deployment, storage and infrastructure.
  • Authentication: Secure user authentication and access systems.
  • Data Connections: Move and connect information between systems.
  • Custom APIs: Create interfaces between different parts of your digital ecosystem.

Make your systems work together.

The best digital products are rarely isolated.

Payments, databases, customer information, communication tools, AI systems and other services may all need to work together.

Integration turns separate tools into a connected system.

Infrastructure

  • Cloud hosting
  • Deployment
  • Databases
  • Storage
  • APIs
  • Authentication
  • Production environments
  • Monitoring
  • Security
  • Scalability

One product. Connected systems.

A digital product may depend on several services behind the scenes.

The goal is to make those services communicate reliably so users experience one connected product instead of a collection of disconnected tools.

Specialist services within Integration & Infrastructure

  • Backend Development — APIs, business logic, authentication services, real-time systems and backend architecture that power digital products.
  • Databases & Data Systems — Database architecture, data modeling, query optimization, migrations and reliable data systems designed around product requirements.

Where integration and infrastructure connect to the rest of your product

  • web application — Every web application we build depends on solid APIs, data and hosting.
  • mobile app — Accounts, sync and notifications in a mobile app rely on the same foundations.
  • AI and automation — Useful AI and automation need dependable connections to your data and tools.

Guides

What shapes the estimate.

Pricing follows the work: what the project needs, what it connects to and what it takes to test and deliver it properly. These are the choices you make in the project configurator.

A typical starting scope (API integrations, Cloud hosting setup): estimated $3,000–$4,000, 4–8 days. Final pricing and delivery timeline are confirmed after requirements review.

Design, development, data and integration work run in parallel where they can, so adding a feature does not simply add its days. Integrations, extra platforms and AI evaluation add the most time.

  • Integration: API integrations, Webhooks, Data synchronisation, Authentication / SSO, System or data migration
  • Infrastructure: Cloud hosting setup, CI/CD pipeline, Monitoring & alerts, Backups, Domain & SSL
