I'm a Full-Stack Developer with hands-on experience in JavaScript, React, Node.js/Express, HTML/CSS, and Git. I build responsive, functional web applications - including a full e-commerce project with product catalog, shopping cart, and REST API integration.
Technical skills:
Frontend: React.js, HTML5, CSS3, responsive design
Backend: Node.js, Express.js, REST APIs
Tools: Git, GitHub, VS Code, npm
In 2024 I completed the Freshcode web development bootcamp, finishing as 2nd best student in my group. I'm currently studying Programming at ZIEIT (Ukraine).
I'm highly self-disciplined, a fast learner, and motivated to take on real freelance projects. I work well independently and communicate clearly in English (B2) and German (B1) - my German improved significantly during a 5-month stay in Switzerland.
I'm open to junior-friendly projects, small-to-medium tasks, and long-term collaboration with clients who value reliability and growth potential.
