API Documentation & Developer Portal

Great APIs lose adopters to bad docs. I write developer-grade documentation that gets a developer to their first successful API call fast: a complete OpenAPI/Swagger reference for every endpoint, a clear quickstart, authentication guides (API keys, OAuth, tokens), error and rate-limit references, and working code samples in multiple languages such as cURL, JavaScript, Python and PHP. The reference is driven by your OpenAPI spec, so it stays accurate and is easy to regenerate as the API evolves — not a static Word file that goes stale the day after you ship.

I then publish it as a real hosted developer portal using Docusaurus, Mintlify or ReadMe — searchable, versioned, branded to your product, with a try-it console where the platform supports it. Versioning is set up from day one so you can document v1 and v2 side by side without breaking links. This suits SaaS startups, fintech and logistics platforms and government-adjacent tech teams across Dubai, Abu Dhabi and Sharjah that are opening an API to partners or customers.

This is specifically API docs plus a developer portal — distinct from my sibling Technical Writing & Documentation gig, which covers general user manuals, internal SOPs, knowledge-base articles and process guides. Choose this gig when the audience is developers integrating your API; choose the general technical-writing gig for end-user or internal operational documentation.

How it works

1. 1
   Audit the API

   I review endpoints, your OpenAPI spec and how developers will use it

2. 2
   Write + sample

   Reference, quickstart, auth guides and working multi-language samples

3. 3
   Build portal + handover

   Publish the hosted, versioned portal and hand over the source to edit
