Full Stack Web3 / Typescript Developer

I am a Full Stack Web3 Engineer with several years of experience building blockchain infrastructure, cross-chain systems, and secure wallet solutions. I’ve worked with EVM, Solana, Bitcoin, Dogecoin, XRP and other networks, developing transaction builders, signer solutions, HD key-derivation libraries, and multi-chain wallet architecture.

My background includes creating cross-chain arbitrage bots, integrating bridges (like cBridge), building APIs and backend services with Express.js, and developing full-stack applications in React, Next.js, and TypeScript. I have hands-on experience with Hardhat, Truffle, Ganache, Mocha tests, and I’m familiar with Solidity smart contracts.

I'm looking for a role where I can contribute to Web3 products involving wallets, blockchain integrations, multi-chain tooling, backend services, or full-stack development — ideally within teams building next-generation decentralized technologies.
