APIs & Integration

REST and event-driven APIs other systems can build on — versioned contracts, webhooks, third-party integrations, and a developer experience that does not need a support ticket.

Most of the platforms I've built are really integration problems: a background-verification SaaS wiring in PAN, Aadhaar, CIBIL and eCourt sources; a multi-vendor API platform for financial institutions with three services behind a shared schema; marketplaces stitched to payment and logistics providers.

The API is a product with its own users. That means a versioned contract that doesn't break them, documentation that answers the obvious questions, webhooks and idempotency for the async parts, and a gateway doing auth and rate limiting so the services behind it stay simple.
