Full-Stack Developer | Node.js | FastAPI | React | React Native

Hi, I’m Vitaliy, a full-stack developer with strong experience in web development. I build complete web products from frontend to backend, including user interfaces, APIs, databases, authentication, third-party integrations, and deployment workflows. My main technologies are JavaScript, TypeScript, Node.js, Express, NestJS, Python, FastAPI, Django, React, Next.js, PostgreSQL, MongoDB, Docker, Git, and TailwindCSS. I can help businesses build new products, improve existing systems, fix technical issues, and ship clean, maintainable features. I work across the full development cycle: • building responsive frontend interfaces • developing backend services and REST APIs • designing database models • integrating external APIs and services • improving performance and reliability • writing maintainable, production-ready code • supporting ongoing product development I also use AI-assisted development tools in my workflow for research, debugging, code review, documentation, and test creation. I treat AI as a productivity tool, not a replacement for engineering judgment. I value clear communication, technical clarity, and solutions that work in practice, not only on paper.
