Top SchoolPiotr Buda is a senior blockchain developer and software architect with 13 years of experience designing and delivering secure, production-grade distributed systems from Poland. He has led end-to-end bridge implementations—deploying an Ethereum mainnet bridge contract and a decentralized verifier network that aggregates signatures for cross-chain transfers—while owning both on-chain and off-chain components. At SoftwareMill he built diverse DeFi primitives and tooling, from lending and staking dApps to arbitrage bots and Chainlink-integrated games, demonstrating strong Solidity, TypeScript and backend skills. His open-source contributions include improving build and deployment workflows for well-known projects like elasticmq, adding GraalVM native-image and optimized Docker setups that speed startup and reduce resource use. Comfortable across smart contracts, Nest.js backends and system-level DevOps, he combines deep protocol knowledge with pragmatic engineering to ship reliable, auditable systems. Notably, he leverages blockchain p2p mechanics to innovate signature aggregation and batch bridging for complex token standards like ERC1155.
