About Me

Front-end engineer with 13+ years of experience building scalable, high-performance web applications for companies worldwide. I specialize in the React ecosystem, design systems, and real-time application architectures, with a strong focus on mentoring, code quality, and medium-to-large product delivery. I started coding at 13 and found my path in front-end—always happy to help others who are just getting started.
