Marco Falke is a seasoned software engineer with 12 years of experience, based in Malmö, Sweden, who specializes in backend development and DevOps for cryptocurrency and blockchain projects. As a long-time self-employed contributor, he has hands-on experience improving core wallet functionality, RPC interfaces, CI/CD pipelines, and test frameworks across high-profile projects such as Bitcoin Core, Dash, Zcash, and secp256k1. He combines low-level C/C++ maintenance and build-system expertise with Rust tooling and test automation, frequently focusing on reliability, security, and reproducible builds. Marco’s work often targets hard-to-detect issues—race conditions, caching bugs, compiler warnings, and fuzzing integration—demonstrating a pragmatic focus on long-term maintainability. Comfortable across front-end tweaks to site privacy and deep cryptographic libraries alike, he brings a rare mix of infrastructure, protocol, and QA skills to open-source critical-infrastructure projects.
