API Development

API development and integration: REST APIs, authentication, webhooks and data synchronisation between systems.

APIs are the contracts between your systems, partners and products. I design them to be predictable, secure and documented — with versioning, rate limits and error handling that clients can rely on.

That includes the other direction: consuming third-party APIs robustly, handling webhooks safely and keeping data in sync without silent failures.

  • Public or partner APIs for your product
  • Backend APIs for web and mobile frontends
  • Webhook processing and event-driven integrations
  • Data synchronisation between internal systems
