I design and build APIs that connect your web and mobile applications. Clean endpoints, proper authentication, solid documentation, and consistent error handling so other developers (and your own frontend) can integrate without headaches.
When your website, mobile app, payment processor, and CRM all need to share data, an API is the connective tissue that lets them talk. I build APIs that other systems can rely on, and I integrate the third-party ones you already depend on.
That means clean, predictable REST endpoints, proper authentication with tokens or OAuth, sensible rate limiting, and documentation a developer can read without guessing. Consistent error handling matters as much as the happy path, because the integrations that break quietly are the ones that cost you.
API work I deliver
Custom REST APIs that power web and mobile frontends from a single source of truth. Integrations with payment gateways like Stripe and PayPal. Connections to CRMs, email platforms, and membership databases so data flows automatically instead of through manual exports. And webhook handling so your system reacts the moment something happens on another platform.
I have built this kind of plumbing for national organizations syncing members, payments, and communications across several services at once. Done right, it runs in the background and you forget it is there.
What this includes
- RESTful API design following industry best practices
- Token-based authentication (JWT, OAuth 2.0)
- Rate limiting, input validation, and error handling
- API versioning and backward compatibility
- Third-party API integrations and webhook handling
