About

I’m a blockchain expert with over 9 years of experience in building and developing blockchain solutions.
I specialize in creating DApps on platforms like Ethereum, Solana, and others. I have strong experience with DeFi systems, NFTs, Hyperledger, Layer-2 solutions, and designing tokenomics. I use technologies such as Solidity, Rust, Web3.js, and IPFS to build secure and scalable solutions.
Besides blockchain, I'm also skilled in Python and Go, and I have experience with both front-end and backend development. This allows me to deliver complete, end-to-end solutions for web and blockchain applications.
