Web3 Full Stack Developer

I'm a Web3 full-stack developer with a strong focus on building modern, scalable applications. Over the past few years, I've worked across the full development stack designing intuitive UIs, integrating smart contracts, and connecting Web3 with real-world use cases.

Currently, I’m leading frontend development team, where we’re building innovative blockchain-based platforms for creators and brands. Previously, at Uniqly.io, I helped develop one of the first Web3 marketplaces linking physical products with NFTs, while mentoring a team of developers and ensuring code quality at scale.

I’m passionate about combining technology, creativity, and blockchain to create products that make a real impact. My work is driven by curiosity, clean architecture, and a hands-on approach to solving complex technical challenges.
