⭐ Full-Stack Developer (React, Node, AI, Web3) | Building Scalable & Meaningful Digital Products

I'm a full-stack developer with several years of experience creating smart, scalable web applications.
I specialize in building AI-driven and Web3-powered solutions — turning complex ideas into simple, functional, and real-world tools.

💡 About Me

Hi there! I come from a philosophy background, where I learned to think deeply, see problems from different angles, and look for clear, logical solutions.

During the COVID-19 pandemic, I got interested in software development — just out of curiosity at first. But the more I learned, the more I saw how amazing it is to turn ideas into real, useful things through code.

What started as a small interest has become my career and long-term focus. Over the past few years, I've been building smart and scalable web applications, from AI tools to Web3 platforms.

My philosophy roots still guide me today — I care about clarity, structure, and purpose in every project. I like building things that actually make sense and help people.
