Über Serhii
Hi, I’m Serhii Iver, a 35-year-old Front-End Developer with over 5 years of experience building fast, modern web applications using React.js, Next.js, and TypeScript. I have a strong background in state management with Redux Toolkit and React Query (TanStack Query), and I enjoy crafting clean, responsive UIs with Tailwind CSS, Material UI, and Ant Design.I'm also experienced with writing tests using Jest and Enzyme, and working with CI/CD pipelines (GitHub Actions, Jenkins). While my main focus is front-end, I’m confident with back-end technologies like Node.js, PHP, MySQL, and MongoDB, as well as server environments (Ubuntu, Nginx, PM2, etc). Looking for an opportunity to join a team as a Middle or Senior Front-End / Full-Stack Developer and contribute to building meaningful and scalable web projects.
