Hi, My name is Anton Datsenko, I'm a entry-level developer. I focused on web development using Ruby(Ruby on Rails), Python and C#. I have good knowledges of basic things - client-server architecture, HTTP protocol, good understanding of MVC pattern, have work experience with MySQL, SQLite. Unfortunately I haven't work experience on real projects but I everyday improve my skills in described technologies on "pet-projects" and I think /hat I ready to try work on real projects, even as support developer.

Ruby on Rails, Ruby, REST API, OOP, JavaScript, SQL, Git, HTML, Bootstrap

I had a team with other developers. We created few cross-platform applications. Also, I created site for travelers with different opportunities.

I would like to de a backend developer. I dream about job in IT office. I want to become a master in IT. I adore coding for hours. Especially, I like to learn new technology, as it gives me more freedom for my fantasy to create something new.

I made the system more reliable by fixing bugs and refactoring code in JavaScript and TypeScript.

Practical skills and theory base Advanced familiarity with computer science concepts, internet and networks. Databases: (SQL), OOP/OOAD and SOLID. Applied experience with C#, ASP.NET Core, DI, API, MS SQL, JavaScript. WebSockets (Chat), Razor and Angular/Vue. Code examples Chat Site Does not use a database, exists only within the session life cycle. There are 2 user roles in the application, admin and user. I used JSON web token authorization (JWT). Before the response is sent to the server, it is serialized in the controller. SignalR is used as a library, and ASP.NET Core 2.2 as a backend. It is also possible to create chat rooms. Library The project uses 3 models - Author, Book and Customer. Allows one customer to read only one book at a time. At this time, the book will disappear from the library for other customers. An author can have many books, as can a customer (one to many relationships). I used only ASP.NET Core MVC 2.2. Forum The project uses 3 models - Forum, Post and PostReply. A forum can have many posts (forum topics), a post can have many replies (posts). One to many relationships. The project uses the Identity authorization system. Only authorized users can create forums, topics and answers. I used ASP.NET MVC 2.2 as a technology and MS SQL as a database.

I was working as a software developer for the third day where I implemented and tested new features like upload blob files in Azure, fixed bugs and made refactorings. I wrote documentation and test cases for the fourth day. My teammate and I successfully defended our project the fifteenth day.
