Certified Blockchain Developer | Ethereum, Solana, Web3

Hey, I’m a certified blockchain dev (BTA) who’s been building smart contracts, Web3 apps, and automation tools on Ethereum and Solana for the past few years. I’ve worked on everything from utility tokens and NFT platforms to automating real-time alerts and building systems that connect on-chain logic with off-chain services. A few projects I’ve built have gone live, sold out fast, and are still running strong. Here’s what I usually work on: Smart contract development (Solidity, anchor) Full-stack dApps (React, Firebase, Firestore, web3.js, etc.) Web3 integrations (wallets, transactions, token gating) Solana tools and automation (wallet listeners, volume trackers, basic bot logic) Telegram integrations for updates/alerts I like working on creative ideas, especially if you're building something fresh in the Web3 space. Whether you’re planning a launch, building a utility around your token, or need backend logic tied to on-chain activity—I can help make it happen. Let’s build something solid.
