APIs & backends
The part your users do not see, but everything else depends on.
Design and development of reliable APIs and backends: authentication, payments, integrations, data and real time, powering your web and mobile applications.
The need
A fragile backend is paid for over a long time: outages hard to diagnose, inconsistent data, breaking integrations and features impossible to add cleanly.
What we build
APIs
Clear, documented interfaces for your applications and partners.
Mobile backends
The server foundation of your iOS and Android applications.
Authentication and permissions
Accounts, sessions, roles and access handled server side.
Payments
Reliable charging, subscriptions and payment webhooks.
Webhooks and integrations
Your tools connected together, without manual re-entry.
Data
Structured data models, controlled migrations, backups.
Real time
Notifications and instant updates where usage justifies it.
Approach
- 01
Understand business flows before drawing endpoints.
- 02
Design the data model as a durable company asset.
- 03
Secure the failure cases: a backend is judged on its bad days.
- 04
Document so other developers can take over without friction.
Engineering
- Server-side input validation and control, never client side only.
- Error handling and retries designed for external integrations.
- Versioned, reversible database migrations.
- Logging and monitoring to diagnose quickly in production.

FAQ
Can you take over an existing backend?
Yes, after an audit of the code and data to establish an honest assessment before proposing an action plan.
Do you work with an existing team?
Yes. The backend can be designed and documented to be operated by your developers, with a clear handover.
How is reliability ensured?
By design: server validation, error handling, controlled migrations and production monitoring. Reliability is not an option added at the end.
