What I'm looking for

I seek a senior engineering role focused on Web3/frontend systems, collaborative Agile teams, impactful projects, mentorship, and opportunities to architect scalable, production-grade products.

I am a Senior Full Stack Engineer with over 7 years of experience building scalable, high-performance web applications and Web3 solutions. I specialize in frontend and backend development using modern JavaScript/TypeScript stacks, and I design full project architectures with an emphasis on clean, testable code.

At Yandex I led migrations to TypeScript, implemented SSR/SEO improvements with Next.js that increased engagement by 25%, and built internal analytics dashboards with real-time APIs. I have also delivered blockchain-first products—NFT marketplaces, on-chain games, and DeFi components—integrating smart contracts, wallets, and on-chain indexing tools.

I mentor junior engineers, drive Agile delivery, and actively participate in hackathons and meetups to stay current. I look for roles where I can deliver impact-driven solutions, improve reliability across the stack, and collaborate on innovative Web3 and frontend experiences.
