What is the best category for me?

[Max Y]

Greetings! 

I filled in my profile, but I am not sure which category is the fittest for my expertise. 

I do write project plans and software specification documents. But there is no such category/service in Upwork as "Project Plan Writing" or "Business Documentation". 

So what service should I choose for my profile that will cover clients' requests in this field?

I think you can go with "Technical Writing" or "Project Management" or "Other-writing" or "All admin support "
