About

  • Background — Software Engineering student focused on frontend and full-stack development. I build modular platforms like SkyVault and SelanFlow with React, TypeScript, Next.js, and Spring Boot.
  • Current focus — UI/UX design and fluid interfaces. In my free time I teach an introductory Java & Spring Boot course for fellow students.
