API & SDK Documentation Services

At CoffeeCup.tech, I provide expert documentation services for APIs and SDKs — from structured reference content to developer onboarding guides. My mission is to make technical information accessible, actionable, and developer-friendly.

I document your API or SDK with both clarity and depth. The result? Devs understand how to integrate, configure, and succeed — without wasting time.

Whether it's a RESTful API, or SDKs for multiple platforms, I deliver structured, well-crafted content that supports developers from onboarding to troubleshooting — all while respecting their workflow and time.

What I Document​

I cover both Reference Documentation and User Documentation, shaped to your audience.

Reference Documentation​

  • Method and function definitions
  • Parameters, optional/required values, best practices
  • Return codes, status/error handling
  • Inheritance and class structure (for object-oriented APIs)

User-Facing Documentation​

  • Overviews and architecture diagrams
  • Getting started guides and tutorials
  • Feature walkthroughs and actionable examples
  • Glossaries and troubleshooting tips

Prefer documentation separate from the code? I can extract the relevant details directly from the source and shape them into a clear, consistent content set.

How I Work​

Docs-as-Code & Dev Collaboration​

I work closely with dev teams, most of the time within docs-as-code environments — using Git, markdown, and CI-integrated tooling to stay aligned with the development cycle. This ensures documentation is versioned, reviewable, and deployed just like code.

See also API and SDK Documentation in the "Expert Tech Writing" section

Technical Fluency​

A key skill in API documentation is the ability to read code in one or more languages and extract what matters most. I read and interpret code in:

  • JSON, XML
  • JavaScript, Node.js, Python, PHP, C++
  • Java (using Javadoc)

I document what matters, where it matters — whether embedded inline or structured as standalone guides.

Tooling I Support​

Your documentation style and platform may vary — and I adapt accordingly:

  • Redoc plugins for Docusaurus-based developer portals ⭐
  • Javadoc and Doxygen for embedded API reference generation
  • Static site generators like Docusaurus⭐, Hugo, or Jekyll
  • Visual Studio Code, Postman, Git, and other dev-friendly tools
