Ваш надійний партнер в пошуку роботи та підборі персоналу
First of all, had a practical task aimed to check my knowledge in JavaScript, HTML and CSS. Performed that task completely with all extra items (see shopping-cart in the portfolio below).
During the internship, started to learn back-end web development with building the Node.js application written in TypeScript (mainly) and JavaScript. Got to know the basic abstraction layers of such applications: database (domain), services and controllers. Understood how to create models and make SQL queries using Objection.js and Knex.js. At the services’ level, implemented CRUD operations for working with a PostgreSQL database. Used Express.js for building a RESTful API at the controllers’ level as well as Joi for data validation and sanitization. Also, realized filtering and pagination. With JWT, performed authentication and authorization. There is a GitHub repository with that application (see bus-station-test in the portfolio below). Unfortunately, due to the economic crisis caused by the pandemic of COVID-19, was not appointed to the job position of junior web developer.
