Although, our main expertise is Python language and related frameworks, we heavily use other technologies. We do lots of mobile developments with cutting edge frameworks and languages. We focus on certain technologies that can benefit us the most and master them to perfection.
We use Python with primarily Django to build web applications as well as APIs for mobile apps. We also work with data analysis and data mining.
Our engineers are specialized on creating native mobile applications. We aim to deliver best performance and user experience.
Technologies listed above are not a complete list. There are dozens of smaller libraries that we worked with. More importantly, we can pick up new technologies if it's needed and can actually benefit the project.
