ProstoAvto

ProstoAvto ("Simply Auto" in russian) was a aggregator webservice for car repairment requests.

Users can create a request, providing detailed information about his/her car and things that need repairment.
Nearby repairment stations and shops reply with offers, and the user picks one he likes best.

I implemented the prototype in three months using ASP.NET MVC and EF6.
It had four integrated regions: for guests, users, repairment station managers and administrators.
The core of the service was a complex filtering system that matches requests to repairment stations by several dozens of criteria.

Unfortunately, the project was abandoned by the creator after having failed to attract investors.
