Since 2010 I develop, integrate and support IT systems in Eurochem Group AG. The software built by myself or with my participation helps companies within the group to produce and deliver 2 millions of metric tons of fertilizers per month.
Most of the projects were implemented in Ruby and Node.js. Some software was also distributed to other industry giants recognized in Russia: Siberian Coal Energy Company (coal-mining), Siberian Generation Company (electricity generation), and Sibur (gas processing and petrochemicals).
Short description of some of my projects is available here.
