Rockstar🎓
Top SchoolDusan Klinec is an Eng-Lead / Staff Engineer based in Prague with 14 years of professional experience and a PhD in applied cryptography, blending deep research in randomness and cryptoanalysis with hands-on backend and security engineering. He leads teams building secure, cloud-native systems (Kotlin/Java/Python, Spring, AWS, Docker, Kubernetes) and has a strong track record in applied cryptography for hardware wallets—most notably integrating Monero support into Trezor and contributing cryptographic primitives across trezor repos. His background spans mobile, smart-card/HSM architectures, high-performance computing, and intensive security audits including reverse engineering and vulnerability research (ROCA, Java deserialization). An open-source enthusiast and frequent contributor, he combines protocol design, implementation, and tooling improvements with practical DevOpsSec experience. Notably, he co-authored a randomness test (BoolTest) and implemented advanced primitives like BulletProof+ in firmware, highlighting a rare mix of low-level crypto engineering and scalable system design.

Monero: the secure, private, untraceable cryptocurrency
Role in this project:Back-end Developer
Back-end DeveloperContributions:59 reviews, 64 commits, 87 PRs in 4 years 8 months
Contributions summary:Dusan contributed significantly to the Monero project's core functionality, specifically focusing on wallet and RPC features. They implemented new features for watch-only and cold wallets, including the handling of unsigned and signed transaction sets, and the import/export of outputs. The user also added a refresh command to the RPC wallet server and improved the codebase by implementing an incremental Keccak API and integrating with HW device support.
