API Development

Why a poorly designed API is a tax on every team that uses it

A bad API makes everything downstream harder. Inconsistent naming, vague error messages, missing pagination, undocumented edge cases — every shortcut in the API layer becomes someone else's debugging session. Whether it's your frontend team, a mobile developer, or a third-party integration partner, they all pay the price.

A well-designed API, on the other hand, is a force multiplier. Consistent conventions mean developers can predict how new endpoints work before reading the docs. Clear error responses mean bugs get fixed in minutes, not hours. Good versioning means you can evolve the API without breaking clients.

APIs are contracts. Once you ship them, they're hard to change. Getting the design right before the first consumer saves you from months of painful migrations later.

How I design and build APIs

I treat API design as product work, not just engineering work. The consumer experience matters as much as the implementation.

• OpenAPI 3.0 specs written first, so the contract is documented before a line of server code is written
• Zod validation on every request body and query parameter — invalid data never reaches your handlers
• Consistent error envelopes with machine-readable codes so clients can handle errors programmatically
• Postman collection included so your team can start testing immediately without reading docs

Whether it's REST or GraphQL, every API I ship is versioned, authenticated, rate-limited, and documented to a standard your team will thank you for later.
