• 2+ years of professional experience with React.js and Next.js
• Strong proficiency in modern JavaScript/TypeScript, React hooks, and component-based architecture
• Experience building and maintaining production web applications
• Solid understanding of Git, responsive design, and web accessibility best practices
• Excellent communication skills and comfort working remotely
