Yellow Gears provides full-cycle software development in domains of mobile and web applications. We also provide software development in Machine Learning and Big Data.

We use following technologies:

  • Scala for back-end development;

  • Java for Android development;

  • Swift/Objective-C for iOS development;

  • AngularJS for front-end development;

See how we manage projects:


Scala is "fashionable" because it helps people solve real problems in an elegant way and runs on what is arguably one of the better platforms (the JVM) currently available and pervasively deployed.


Emerging as a next-generation generalized engine for large-scale data processing, Spark is an open source Apache Foundation project that enables organizations to perform in-memory analytics on big data sets.

Play Framework

Anyone who has worked with Play Framework will tell you that it's fast. Play, which was recently ranked in a RebelLabs report as the 6th most-used web framework among Java developers, does all it can to wring every last drop of performance out of the JVM.In fact, many customers find that Play works so well that they are able to retire servers after moving to Play.

Akka Framework

We believe that writing correct concurrent, fault-tolerant and scalable applications is too hard. Most of the time it's because we are using the wrong tools and the wrong level of abstraction. Akka is here to change that. Using the Actor Model we raise the abstraction level and provide a better platform to build correct, concurrent, and scalable applications.


Achieve the maximum speed possible on the Web Platform today, and take it further, via Web Workers and server-side rendering. Angular puts you in control over scalability. New conventions make it easier to learn and faster to develop apps.


Bootstrap is the most popular HTML, CSS, and JS framework for developing responsive, mobile first projects on the web. Bootstrap makes front-end web development faster and easier. It's made for folks of all skill levels, devices of all shapes, and projects of all sizes.


Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets.


iOS is the mobile operating system that runs on Apple’s mobile devices, i.e. iPhones and iPads. It’s the main software that allows you to interact with your Apple phone or tablet.

CMS WordPress

Originally built as a blogger platform, WordPress is arguably the easiest to use and the most popular. Initially released in 2003, it has grown rapidly since. The WP platform is used for over 60 million websites, and 100,000 new websites are created daily. WordPress is best for static content. However, WP sites are often built for complex, dynamic solutions because the community is so large and has added so many capabilities. The structure of the company behind WordPress, Automattic, and its philosophy represent the ability for large growth with such an open-source project.
