Technical overview
How I design APIs and integrations
API work is half design and half integration discipline. I build versioned REST endpoints and GraphQL schemas with pagination, consistent error JSON and OpenAPI docs that frontend teams can rely on.
OAuth2, API keys and rate limiting protect public surfaces. Webhook receivers verify signatures and stay idempotent, especially where payments or order status can retry. Queues absorb spikes so a slow third party does not time out the storefront.
Before writing glue code I map fields between systems. Mismatched IDs between ERP, CRM and catalogs cause more damage than missing endpoints. Legacy SOAP appears when partners still require it; I isolate that XML behind clean adapters.
Common API tasks I help with
- How to version a REST API without breaking existing clients
- How to design consistent error responses for frontend handling
- How to verify webhook signatures and ignore duplicates
- How to map fields between CRM, ERP and a web catalog
- How to add rate limiting without blocking legitimate traffic
- How to document an API with OpenAPI and example requests
- How to introduce GraphQL where nested reads dominate
- How to bridge a legacy SOAP service behind a modern adapter
- How to queue outbound calls when a third party is slow
- How to rotate API keys with overlapping grace periods
