API integration consulting for complex systems

Design for the provider’s actual behaviour

A successful example request is only one part of an integration. Providers paginate differently, enforce rate limits, change schemas, delay events and sometimes recover from outages by sending data again. I build around the guarantees and limitations the provider actually documents and demonstrates.

• REST API and webhook implementation
• Authentication, credential handling and pagination
• Rate limits, schema normalization and provider changes
• Ingestion and enrichment across multiple data sources

Keep cross-system data consistent

When two systems describe the same record differently, the application needs explicit rules for ownership and reconciliation. I help establish how data is mapped, how duplicate or out-of-order events are recognized, and how an operator can review unresolved exceptions. Those behaviours can live in a Node.js backend and use AWS event-driven infrastructure when the system calls for durable asynchronous processing.

• Retries, idempotency and duplicate detection
• Data synchronization and reconciliation paths
• Provider outages, replay and exception visibility
• Integrations that use background processing where needed

Experience across provider-heavy products

My professional work includes insurance API integrations at Briza, travel-provider integrations at N-iX and company research and enrichment pipelines at HoneySales. In each case the application had to account for provider-specific data and behaviour, not just make the connection.
