Особисті якості

Hello everyone!

I am a Frontend Developer with 2.5+ years of commercial experience building web applications with React and Next.js.

I have experience delivering features end-to-end, both independently and in small cross-functional teams. My main strengths include REST API integration, authentication flows, data-heavy interfaces, forms and validation, responsive UI, multilingual interfaces, and close collaboration with designers, back-end engineers, QA, and PMs.

On the frontend, I work with React, Next.js, JavaScript, TypeScript, SCSS, Tailwind CSS, Redux, React Query, React Hook Form, WebSockets, and i18n.

I am also expanding into full-stack development with Python and FastAPI. My backend experience includes building REST APIs, working with PostgreSQL, Redis, SQLAlchemy, Alembic, Docker, JWT authentication, role-based access control, file uploads, email flows, caching, and automated tests with Pytest.

Currently focused on frontend and full-stack roles where I can build complete product features with React/Next.js on the frontend and Python/FastAPI on the backend.

If you are looking for a Frontend Developer with strong React/Next.js experience and the ability to contribute across the full stack with Python/FastAPI, feel free to reach out. Let’s connect!
