I specialize in Solidity development, particularly in ERC-721/1155 standards, generative NFTs, dynamic traits, and off-chain data integrations. 🔹 NFT Smart Contracts – I’ve developed and deployed ERC721 & ERC1155 contracts with gasless minting, trait logic, airdrops, token-gating, and royalty splitters. 🔹 Dynamic Metadata – Built dynamic NFT systems where metadata updates based on external conditions (user behavior, Chainlink oracles, backend events). 🔹 Backend + Web3 Integration – I create complete NFT minting flows with FastAPI/Node.js backends, integrating IPFS, on-ramp services (e.g., Stripe), Chainlink, and tokenomics logic. 🔹 Security & Gas Optimization – I follow best practices for security (my code has passed Certik audits) and write efficient, scalable smart contracts. 🔹 Tech Stack – Solidity, Foundry, Node.js, FastAPI, Chainlink, PostgreSQL, Biconomy (AA), React, IPFS. I’ve worked with global startups (France, UAE) to build NFT platforms, DeFi protocols, and gamified dApps — all remotely.
