Summary
🤩
Rockstar🎓
Top SchoolRichard Meissner is a Swiss software leader and Co-Founder with 11 years of experience building developer-facing blockchain infrastructure, most recently driving Safe (safe.global) after a five-year technical leadership stint at Gnosis. He blends backend and full‑stack craftsmanship—shipping SDKs, provider integrations, and Solidity work for account abstraction and multisig flows—while also tackling QA and test automation to harden critical crypto primitives. His open-source contributions to widely used projects like hardhat-deploy and Safe Core SDK demonstrate deep practical knowledge of deterministic deployments, signers, and transaction handling. Comfortable moving between low-level smart contract optimizations and UX-facing Safe Apps, he brings an engineer’s rigor from Hasso‑Plattner‑Institut and a track record of improving gas efficiency, deterministic deployments, and developer ergonomics.
