Solidity Developer
Blockchain developer with a genuine passion for decentralized technology and solving complex problems. I love taking on challenges that require thinking differently and exploring new approaches. Over the past 4+ years, I've worked on 27+ projects spanning DeFi protocols, NFT ecosystems, and multi-chain solutions—each one teaching me something new. I'm naturally curious, open-minded, and driven by the belief that blockchain can genuinely change how we interact with technology. Always eager to learn, collaborate, and tackle problems that push me outside my comfort zone.
