Freelance Blockchain Engineer – Full Stack & Web3

Active over a week ago
🌱 Member since June 2025

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'm available for freelance missions focused on Web3, Python backend, smart contracts, or hybrid tech+UX products.
