Desktop App for Photo & Keyword Search

I'm looking for a Windows-based desktop application that allows users to upload a photo or type in a keyword to search for similar items in a local database. This app should support both input methods - photo uploads and keyword typing.

Ideal Skills:
- Proficiency in Windows desktop application development
- Experience with creating search algorithms for databases
- Skills in handling multimedia input (photos)
- Ability to implement user-friendly interfaces
- Knowledge of keyword matching techniques

Experience with similar projects would be highly beneficial. Please provide examples of previous work that you feel may be relevant.
