API development that other systems can build on.

It's designing and building the interface other software calls to use your system: the endpoints, the request and response shapes, authentication, versioning, rate limiting, and documentation. The goal is an API that's deliberate, secure, well-documented, and stable enough that other developers, your own frontend, your partners, or the public, can build on it with confidence.

It depends on your consumers. REST is simple, cacheable, and familiar, and it fits most public and service-to-service APIs well. GraphQL shines when clients need to fetch varied, nested data in one request and you want to avoid many round trips, common for rich frontends. We choose based on who's consuming the API and how, and sometimes offer both.

The API is the interface; the backend is everything behind it. API development focuses on designing that interface well: its contract, security, versioning, and developer experience. Backend development is the broader engine, business logic, data layer, background jobs, and infrastructure, that the API exposes. They overlap, and we often do both, but if you already have a working backend and need a clean interface to it, that's specifically API development.

Building an API means creating and exposing your own interface for others to call. Third-party integration is the reverse: connecting your software to an external service's API, like a payment provider or CRM. This service is about the API you provide; if you need to consume APIs someone else provides, that's our third-party integration service, and the two often go together.

With layered controls: authentication so every caller is identified, scoped authorization so each reaches only what it should, validation on every input, rate limiting to blunt abuse, and secrets kept out of code. We also design for least privilege and log access, so an API is safe to expose publicly rather than only behind your firewall.

Yes. We can design and add a clean, documented API to a system you already run, exposing its data and functionality to your frontend, partners, or other services without disrupting what works. We start by understanding the existing code and data, then build the API as a well-defined layer on top.
