About

Professional summary

I am a Junior Frontend Developer focused on building responsive, user-friendly web applications with React, TypeScript, and JavaScript.

I have hands-on project experience developing e-commerce, travel blog, audio streaming, and movie platform applications. My work includes authentication, protected routes, CRUD functionality, API integration, state management, form validation, and adaptive layouts.

I use React, TypeScript, Redux Toolkit, React Router, Axios, HTML, SCSS, and REST APIs to create maintainable client-side applications. I also have experience with Node.js and Express for developing backend API functionality.

My technical education developed my systems-thinking skills and ability to work with complex algorithms. For my thesis on sign language recognition using machine learning methods, I used Python.

I deliberately transitioned into frontend development because I enjoy seeing the direct results of my work and improving user experience. I am responsible, self-motivated, eager to learn, and looking to grow within a team working on real-world products.

My next goals are to deepen my knowledge of Next.js and frontend testing with Jest and React Testing Library, grow toward a confident Mid-level developer, and eventually contribute to architectural decisions on larger projects.

Frontend Developer Frontend Development Projects

I developed several frontend and full-stack portfolio projects using React, TypeScript, JavaScript, HTML, SCSS, and REST APIs. My work covered responsive interfaces, reusable component-based architecture, API integration, authentication, routing, form validation, and client-side state management.

For an online lighting store, I implemented JSON product loading with pagination, filtering and sorting, a LocalStorage shopping cart, Swiper product slider, Tippy.js availability tooltips, validated feedback forms, FAQ accordion, city selection, and burger navigation. The application used modular JavaScript architecture.

For the TravelBlog SPA, I built registration and login flows, protected routes, post CRUD operations with image uploads, comments, profile editing, API interceptors, loading states, and error handling. I used React, TypeScript, React Router, Axios, Context API, React Hook Form, Yup, and SCSS.

I also developed a full-stack music player and a VK Marusya-inspired movie platform. These projects included Redux Toolkit state management, audio playback controls, Express REST APIs, search with debounce, favorites, modals, adaptive interfaces, and LocalStorage-based sessions.
