Frontend Developer

I am a dedicated software engineer with 3 years of professional experience, and a total of 5 years including personal projects.

I specialize in frontend development with TypeScript, React, and Next.js. My goal is to take on architect and tech lead roles — driving teams through technical excellence.

I am actively expanding into infrastructure (AWS, Firebase) and AI-driven development to strengthen my design capabilities beyond the frontend.
