Solidity And Blockchain Devloper

I am a Solidity and blockchain developer with hands-on experience in building secure, scalable smart contracts and decentralized applications (dApps). Proficient in Ethereum development, I specialize in writing and auditing smart contracts using Solidity, and integrating Web3.js/ethers.js for seamless frontend interaction.

My expertise includes working with protocols like ERC-20, ERC-721, and ERC-1155, as well as platforms like OpenSea, Seaport, and Layer 2 networks. I’m skilled in deploying contracts, optimizing gas usage, managing token standards, and building NFT marketplaces and DeFi platforms.

Actively engaged in the Web3 community, I continually refine my skills and stay updated through platforms like web3.career,collaborating on innovative blockchain solutions that drive real-world value.
