AI based Object Recognition App

I'm looking for someone to build an app where I need to be able to upload architectural drawings and set 'Classes' where the app will be able to recognize DOORS ONLY and identify position and assign specific class to each door. If you read this job description, please right 'Lever' at the beginning of your bid. The process is usually called 'Door Hardware Specification' where estimator will be able to identify doors on the drawings and then assign specific products, normally lever handles or hinges to that specific door.

Please show me some work you have done before relevant to this project.
