👨‍💻I’m a Software Developer moving from Web2 to Web3 and would love to #connect with people interested in:

🔗 Web3
⚡ Smart Contracts
💰 DeFi
🛠️ Solidity & Foundry
🌍 Ethers.js & Wagmi

💡Open to learning, sharing, and collaborating. Let’s #learn and build together!

The small details are what make Web3 dApps feel professional.
🎯 Next: final design tweaks + writing tests for the smart contract + deployment
