Swagger
Swagger (now known as OpenAPI) is a crucial tool for designing, building, documenting, and consuming RESTful APIs. It provides a standardised, language-agnostic interface to describe your API's functionality, allowing both humans and computers to understand and interact with it without needing access to source code, documentation, or network traffic inspectors. For businesses relying on APIs, Swagger is essential for streamlining development, improving collaboration, and ensuring high-quality API documentation.
What to look for in Swagger freelancers
When hiring a Swagger freelancer, look for demonstrable experience in designing, building, and documenting APIs using the OpenAPI Specification. A strong understanding of RESTful principles is vital, along with proficiency in relevant tools like Swagger UI, Swagger Editor, and code generators. Experience with different API frameworks and programming languages is also beneficial.
