 PROJECTS

X-mini
X-mini is my big pet project. It was exciting to implement the main
functions of the social network X (Twitter). The project architecture,
database system (Firebase) — absolutely everything was created from
scratch. I was interested in practicing real-time updates, so I implemented
chats between users. Other implemented features: registration /
authorization (including Google authorization), editing profile data, posts,
replys, likes, bookmarks, subscriptions, user search.

Technologies: JavaScript, React.js, react-router-dom, react-hook-form,
redux-toolkit, RTK query, redux-thunks, styled-components, Firebase.

EduLearn Platform
EduLearn is an educational platform designed to offer online courses and
tutorials to students. The goal was to create a user-friendly interface for
browsing courses, enrolling in classes, and accessing multimedia content.
I worked on building the course listings, user dashboards, and updates for
course progress. Additionally, I integrated features for user authentication
and content rating.

Technologies: JavaScript, React.js, Redux, Axios, React Router, Styled-
components.

TravelMate
TravelMate is a travel booking website where users can search for, book,
and manage their trips. The main task was to develop a responsive
website with functionality for browsing available destinations, viewing
pricing and availability, and making bookings. The project required me to
focus on providing a smooth user experience and creating a fast, intuitive
booking process.

Technologies: JavaScript, React.js, Redux, React Router, Axios, Mapbox
API, Styled-components.
