Blockchain dev

I specialize in developing and testing smart contracts on Solidity/EVM. I have implemented contracts for vesting, swap, erc20, erc721, auction, 1155, using Hardhat for deployment and testing + ethers/web3js. I also have experience working with Rust for the Solana blockchain. Additionally, I am involved in development payment mocks for payment system integrations. My technical stack includes Solidity, JavaScript/TypeScript, Rust, Go, MySQL, PostgreSQL, Clickhouse, Apache Kafka, Docker, and Kubernetes. For perfomance testing, I use JMeter, Grafana, and InfluxDB....
