Senior Frontend Engineer | React, Vue & Web3

Frontend Engineer with 8 years of commercial experience building scalable web applications, financial products, and blockchain-based platforms.

Over the last several years, I have focused primarily on Web3, DeFi, and crypto products, including launchpads, staking platforms, wallet-integrated applications, and blockchain-based financial systems. I have extensive experience building complex user interfaces with React, Next.js, Vue.js, TypeScript, and modern frontend architecture patterns.

My expertise includes wallet integrations, on-chain transaction flows, Web3 user experiences, KYC onboarding, real-time applications, performance optimization, and frontend architecture. I have worked closely with product, design, backend, and blockchain teams to deliver secure and scalable solutions used by thousands of users.

I am passionate about building intuitive products at the intersection of finance and blockchain technology and am currently looking for opportunities in Web3, DeFi, crypto infrastructure, fintech, and high-growth product companies.Β
