Javascript Developer & Node.js Developer

The candidate is a Node.js/Typescript developer with half a year of experience. However, he has almost 15 years of experience in C++, where he programmed machine control for raster image processing. Last year he started to learn C#, GraphQL, Golang. In February he started working on a project in Node and Typescript. For databases, he worked in MongoDB, which ran on the cloud. He has also worked in SQL in the past and has now started learning it again at home. The project he worked on ran Node on Kubernetes and it was deployed in Docker, so he understands how these technologies work. He's also worked with Rust, Git, and Github. He knows how Scrum works, but doesn't have hands-on experience with it yet. Speaking in English is a problem for him as he hasn't communicated in it for 10 years. However, written communication and understanding of spoken text does not bother him. He enjoys working on the back-end and Cloud technologies.
