Make dreams come true

The client calls his project an American dream – started from a small idea and turned into a solution that helps to find a car around the country. He came to us to bring his ideas to life and make people’s lives better.


We had the mission to develop software that will make the buying, and selling process more efficient, transparent, and flexible.

Productivity enhancement

Ensure the stable performance of the website and redirect all users from the legacy system avoiding duplications of the resources.

SPA and high-load data

Implement a Single Page Application (SPA) using React JS and transfer high-load data into the CSV format for inventory-list of vehicles.

Third-party integrations

Carry out the integration with third-party platforms to set up advertising, analytics, payments, and vehicle history reports (Google, Facebook, AWS, Stripe, Vinaudit).

SEO optimization and search capacity

Provide the same amount of traffic as on the old site and enable the search for vehicles/dealers by a wide variety of filters and geo-distance.

Parallelization process

Perform a calculations parallelization on the server to significantly reduce the time required to import the inventory data.



As a result, we developed three websites and applications for iOS/Android:

  • For users
  • Buy or sell a car.
  • Search by brand, model, body style, price, color, and many more popular options.
  • Find dealers near the user’s location.
  • View exclusive private-seller listings.
  • Save favorite vehicles with one tap for later viewing.
