- I developed ready-made modules for online stores to be reused in other projects within the company. This
resulted in the creation of seven online stores, using React and reduced code duplication by 20% and increased
the efficiency of new component development.
- Developed an educational platform for language learning:
- In this project, I built an interactive test and exam system from scratch, consisting of various types of
questions and time limitations.
- I also developed personal accounts for users with the roles of student and teacher.
- The platform includes functionality for students to sign up for online classes, track their progress, and view
their achievements.
- Teachers can create, edit, and delete courses and lessons divided into topics, as well as schedule online
lessons.
- Registration for the exam is also done through the personal account.
- Additionally, a full-fledged forum was implemented where students can ask questions, and other users can
respond to their posts.
- In this project, I learned how to track and fix bugs, as well as collaborate efficiently with backend
developers.
- In addition to frontend development, I also had the chance to work on the backend. I'm familiar with MongoDB,
Node.js, and Express, and I independently developed a small cryptocurrency exchange:
- In this project, I worked with WebSocket. Using Binance's open API, I set up real-time cryptocurrency price
updates directly from the real market and displayed them on the website.
- I stored all user requests in MongoDB and added functionality for the admin to change the status of a
request or delete it.
- I do code refactoring, optimize React component rendering with React.memo and useCallback. Frontend
performance has increased by 50%, significantly improving the user experience.
