A software development kit (SDK) is a collection of specific tools. With SDK, you can quickly and efficiently create an application for a specific platform. SDK allows you to use what has been written and tested before for your solution. SDK is widely used by our team to implement various solutions. The use of ready-made parts of solutions in work helps to significantly reduce development time and the number of errors in the product. We have extensive experience in using various SDKs and believe that this is the solution that should be in service with every development company.
