🚀 Full-Stack Web3 Developer | Solidity & Next.js 

I'm a Full-Stack Web3 Developer specializing in smart contracts and dApps, with hands-on industry experience ranging from trading to liquidity provision. 
My projects aren't just tutorials - they're production-ready solutions with robust architecture, comprehensive testing, and detailed documentation. 

🔧 Tech Stack: 


  • Smart Contracts: Solidity (Hardhat, Foundry), OpenZeppelin (including upgradeable), Ethers.js, Mocha/Chai 
  • Frontend: Next.js (App Router), React 19, TypeScript, Wagmi, Viem 
  • Infrastructure: IPFS/Pinata, Alchemy, Etherscan API, Vercel, ABI automation 
  • Practical Experience: Sepolia deployments, DeFi (DEX, LP), native crypto trading 

🌟 Flagship Project - ERC-1155 NFT Marketplace: 
Built from scratch with: 


  • Combined FT/NFT exchange with advanced business logic
  • Optimized frontend (Next.js, TypeScript) Complete test coverage (TDD approach) Professional documentation (JSDoc, Markdown) 
👉 GitHub Repo (https://github.com/FNuzhdin?tab=repositories) 

💡 What Makes Me Stand Out: 


  • Versatility: Full-cycle development from contracts to frontend 
  • Product Mindset: Active DeFi/DEX user understanding real pain points 
Soft Skills:


  • Communication: Former psychologist with exceptional listening/clarity 
  • Leadership: Experience organizing team workflows 
  • Discipline: Rigorous self-code reviews and deadline adherence 

🌍 Open to Relocation (worldwide) or remote work. English - B2 (technical documentation, corporate communication). 

🔮 My Goal: To become a lead developer in Web3 where I can: Solve real-world problems (from prototyping to scaling) Thrive in fast-paced environments (quick to adopt new chains/frameworks) Contribute to strategic decisions
