I design and develop end-to-end Web3 products: wallets, marketplaces, dApps, trading algorithms, and crypto e-commerce platforms. My approach is fullstack — from frontend interfaces to smart contracts — with a strong focus on UX, security, and scalability. 💡 I often contribute to product vision: Web3 messaging, community hubs, referral systems, and optimized routing algorithms. 👨‍💻 On the tech side, I'm comfortable with Angular and React on the frontend, FastAPI and Django on the backend, and Solidity / Hardhat for smart contracts. I also use Rust to build high-performance modules. 🛠️ Recent projects include: • A Web3 wallet with messaging and community hubs • A multi-DEX crypto swapper with a Rust module for route optimization • A blockchain-based gaming platform (NFTs, ERC20, secure backend) • A crypto e-commerce platform with on-chain conversion I am available for freelance missions in Web3, Python backend, smart contracts, or hybrid tech + UX products. I am also open to full-time opportunities if the project is a good fit.
