In summer of 2011 I started an outsourcing company, hired 2 developers, and began working with clients. We developed a portal with new Bollywood trailers and ratings for our first clients. The project consisted of an admin part and a front-end. We also incorporated Amazon hosting. The live portal now has over 10k Facebook "likes".


B2B software developed for our second clients, a Holland-based software company. They helped them to build a financial product for commodity trading. We worked overtime for 2 weeks to ensure they meet their demo deadline. We also met with their client at Dnepropetrovsk and worked there for a week.
From a technical point of view, the project was simple but had many business logic rules and transactions. DHTMLX was used as the main UI library, which proved to be difficult to customize.


"Realm Of Empires is a serious strategy game for hardcore gamers." - BDA Entertainment website
I started to work with this company in 2009, implementing JavaScript features. My role was to make the game experience more lite. I also worked on Facebook Credits and Gifts that needed development and debugging on the server.
For several months, I worked on a game called MyHarem, a clone of the Mafia Wars Facebook game.
In the year following a big contract, I returned to this project to assist in the launch of a HTML5/mobile version of the game. One of the biggest goals was to make a new map to be touch-movable like Google Maps and offline capable with WebSQL. We achieved interesting results and were able to compare the capabilities of the first generation iPod Touch to the Samsung Galaxy S3.
For more details you can look at the blog and Twitter of my team leader.


A platform I developed for B2B systems that includes many features and smart integration.
