About Me

I am a software engineer specializing in modern TypeScript architectures across frontend and backend. Starting from a strong foundation in Software Engineering, I have continuously advanced my technical expertise—architecting high-performance backend systems and responsive user interfaces.

Always adapting to cutting-edge web ecosystems—such as SvelteKit, Bun, and Hono—I focus on efficient data architectures, clean and maintainable code, and scalable solutions that eliminate technical debt.
