In which field does the man work?

WB You’ve been named one of the top architectural design firms in the midwest. Tell me, how long has your company been in business?
MA From nineteen ninety-one until two-thousand-one, we... I should say I... operated as a sole proprietorship. I hired subcontractors as needed, but did most of the work myself. I formed a corporation in two-thousand-two, due to all the design work I was getting.
WB How many employees do you currently have?
MA We work with a group of regular subcontractors— architects, interior designers, contractors, and so on—who get together on a project-by-project basis. We find this flexibility allows us to address the specific demands of each project, regardless of its complexity or scope.
