Additional Information
I have extensive experience with infrastructures hosted on both on-premise and in cloud platforms (AWS), which makes it possible to quickly localize and fix technical problems of customers, and help companies grow their customer base by implementing and maintaining high-availability infrastructures.
English is not my primary language. I can read and write in English, but I haven’t had any practice in spoken English, so sometimes I have trouble communicating verbally.
