API and tools
I have extensive experience creating API documentation. For example, from 2023 to present (2025), I have taken an established software company with a complex set of APIs from having no API documentation to having a robust and detailed API reference for each API. This documentation has increased company revenue by attracting new customers and also helping to retain existing customers who demanded documentation for the APIs. For this company alone, the API references that I created include more than 50 pages and 200 endpoints.
The following links show you two pages out of the various large API references that I created:
API documentation and testing tools
For testing APIs and gathering the information for documentation, I have used various tools. The tools I've used most often are Postman and Swagger (OpenAPI). For small demonstrations of what I can do in those tools, see the following sections.
Postman
To demonstrate my capabilities for building API documentation with the Postman Collections tool, I created the following small sample doc sites:
OpenAPI
I created an API documentation site on github that uses data from the Swagger PetStore Sample API. I built the site with OpenAPI. I'm very experienced with CSS, so I can style sites like this to fit any branding and format that a company needs. You can see this site here (opens in a new tab).
Madcap Flare and Zendesk
For publishing API documentation, I have also used various methods. I have published with Postman and OpenAPI (as demonstrated in the preceding sections).
To fit the requirements of one company, I created a large API documentation set that I published simultaneously (content reuse in multiple channels) to a Madcap Flare site and a Zendesk Guide Help site. The following links show you two of those pages:
API course certificates
Also, here are certificates for a few of the API courses that I've completed.
