Frontend Developer — Building high-performance, SEO-optimized, and scalable web and mobile applications with React, Next.js, TypeScript, and React Native.
I'm a frontend developer with 3 years of professional experience, specializing in React, Next.js, TypeScript, and Node.js. I transitioned to full-stack development in 2024 and am currently advancing my expertise in React Native and Expo for cross-platform mobile applications.
I'm passionate about design systems, component architecture, and leveraging AI-assisted development with Cursor and Claude Code to accelerate my workflow. I thrive in Agile/Scrum environments and focus on performance optimization and delivering pixel-perfect UIs that drive user engagement and business results.
