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).

  • Parallelization process

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

  • 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.



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

  • For dealers:

    Review the list of leads that come from the web site and external sources

    View user's statistics: popular cars in the search, what ads attract more attention, how often users click on the dealer's contact information, etc

  • For admins and dealer account managers:

    Manage users and dealers

    Watch the statistics of dealers

    Connect or disconnect third-party service applications

    Add advertising banners
