Available to hire
I am Marco Migliorini, a blockchain developer and senior software engineer based in Florence. I specialize in building blockchain-based infrastructure, DeFi, smart contracts, and scalable backend systems, with a strong focus on education around Bitcoin and Web3. I enjoy planning and hands-on work across both blockchain and backend domains, delivering practical, secure solutions and sharing knowledge with peers and clients.
Over the years I have designed token ecosystems, integrated Chainlink and Uniswap across multiple EVM networks, and led training programs to help teams and individuals understand cryptography, solidity, and secure software practices. I value clear architecture, robust testing, and thoughtful engineering that scales with business needs.
