Services and Techs

We are IT polyglots, problem solvers, samurais of the digital age able to work with the most challenging projects. We are communicative and detail oriented.

Ruby — Proficient Ruby on Rails development is not possible without mastering the programming language it's built on, Ruby. We are Ruby ninjas, we breath and dream in Ruby. We use pure Ruby to create scalable standalone apps within Service Oriented Architecture, or ultra fast RESTful APIs (Goliath, Grape, Sinatra).

Data Harvesting and Big Data — we are experts with building distributed Big Data systems. Do you need to source data for particular industry? Do you need insights into and cross-match between different data sources? We've done it! Looking for Real Estate market data? Look no further!

Ruby on Rails — We are Ruby on Rails experts. While Ruby on Rails is excellent framework for rapid web application development, it is fairly easy to get application code into state where it gets more and more expensive to develop and maintain. We keep our bar high. We apply the best practices and design patterns and have tight code review process in place so the code we create is readable and maintainable in the long run; we know how to write tests so the test suite is quick to run and it does not miss any parts that should not be missed; our specs read just like documentation.
We can perform legacy system upgrades and performance improvements for both back- and front-ends.

IT Solutions with JRuby, Node.js, Elixir and Clojure — We are IT polyglots, problem solvers able to work with the most challenging projects. We always apply the best technology to given problem. We have had Java exposure therefore we know how to utilize its power with JRuby and Torquebox. We are also fans of Functional Programming and Clojure.

Full Stack, Front-End and Mobile Development — We provide all-round full-stack services where we craft the apps from back- to front-end. We build Ember.js, Angular and Backbone apps that are driven by metal Ruby on Rails APIs. We have experience building native iOS apps as well as multi-platform mobile applications with Appcelerator Titanium.

Spree and eCommerce — We developed numerous Spree eCommerce websites and we can build custom eCommerce solutions with Spree tailored to your needs. Multi-tenant Spree platforms, online store and Point of Sale with single inventory management, Single Page Applications front-ends (e.g. Ember.js), Mobile Applications driven by Spree API, custom dashboards and reporting - we've got all this covered.
