I have been working for Magento for last 6 years. I designed such functionality as Magento 2 Search and Assync operations (for EE), Catalog Inventory. Also I’ve been involved into many general stuff routines as Magento 2 Service Contracts and performance optimizations on different levels. Currently I work in Community Engineering team and consider this as a great opportunity which will bring Magento onto another level. Because if you want to be an Open Source you have to keep "the door open" for Community’s contributions and ideas. I lead Multi-Source Inventory (MSI) project, which suppose to introduce Multi Stock functionality into the M2 platform. This big and very important core functionality is being developed and designed in a community driven way. Which is a unique experience for all the participants and Magento itself.
