I mainly work with JavaScript. I know CSS, HTML, JQuery. I like working with Node.js and create the logic of the application, implement APIs, Oauth2, functionality, communication between different parts of the application. I work with MongoDB. I have decent experience with Chrome Extensions, including Native Messaging, and various extension APIs. I also work with userscripts. I have experience with WordPress and creating web pages, but prefer to work on the logic of the application, and not on the design.
