What I'm looking for

I am looking for freelance blockchain/Web3 work focused on custom Telegram bots, DeFi tools, and smart contract development with reliable, collaborative partners.

I am a seasoned developer passionate about blockchain and Web3, programming since 2010 and specializing in crypto scripts, bots, and smart contracts since 2020.

I build Telegram bots for DeFi traders and led scan_tools for monitoring new token creations across ETH, BSC, Base, and AVAX; I also developed ETH_SPYBOT and BSC_SPYBOT for real-time wallet transaction tracking.

I work with JavaScript/Node.js for backend and bot development and Solidity for tokens and multi-hop DEX swaps; I hold a Certified Solidity Developer (CSD) certification from Blockchain Council and am seeking freelance blockchain/Web3 projects.
