🇺🇦 Hi, I am Yurii Bezsmolnyi, Full Stack Developer from Lviv, Ukraine 💪🏼 5+ years of experience in React and Node.js 💫 Worked on 8+ challenging projects across various domains 👀 Focused on creating and delivering products from ideas to successful outcomes 🔗 Experienced in building modern web solutions and blockchain technologies ✨ Also, develop personal projects to explore new tools and improve skills CV - blackblud.notion.site/Yurii-Bezsmolnyi-Full-Stack-Web-Developer-ca9571b31ec74175aebf7a2f855fe276

I’ve helped my clients launch and improve products used by thousands of users, reduce load times by 30-50%, and deliver features that directly supported revenue-generating flows. I work primarily with React, Next.js, TypeScript, and modern CSS, building production-ready interfaces that are fast, reliable, and easy to maintain. I’m comfortable working across the full stack when needed, connecting frontend logic with APIs, databases, and real-world product workflows. Alongside that, I have a strong interest in Web3 and blockchain systems. I’ve worked with wallet integrations, smart contract interactions, and dApp frontends, and I actively follow developments around EVM, L2 solutions, and scaling technologies. For me, Web3 is not separate -- it’s an extension of building solid, real-world applications. I value clear communication, ownership, and thoughtful implementation. If you’re building something meaningful and need a developer who thinks beyond just code -- let's have a chat.
