Резюме

👋 Hey there! I’m Vasyl, Senior Frontend Engineer with 8+ years of experience building scalable, high-performance web applications. I love crafting clean, intuitive, and efficient user experiences that not only look great but also perform seamlessly across devices.

💡 What I Do Best:
- I specialize in React, Next.js, and TypeScript, creating modern, responsive UIs with Tailwind CSS, SCSS, and Styled Components.
- I have a deep understanding of state management (Redux, Context API) and API integrations using GraphQL and REST.
- Performance is a priority - I optimize apps with SSR, SSG, and lazy loading to ensure speed and efficiency.
- I believe in automation and smooth workflows, leveraging CI/CD, Jest, Cypress, and Docker to keep development streamlined.
- I thrive in collaborative environments, working closely with designers, backend engineers, and product teams to turn ideas into reality.

🚀 My Journey So Far:
Throughout my career, I’ve had the opportunity to work on high-traffic applications, contributing to platforms that serve millions of users globally. I enjoy solving complex problems, improving performance, and mentoring fellow developers to help teams grow and succeed.

🎯 What Drives Me:
I’m always eager to learn new technologies, experiment with innovative solutions, and push the boundaries of frontend development. My goal is to create digital experiences that are not just functional but also delightful for users.
