Rockstar🎓
Top SchoolRichard Kiss is a seasoned back-end engineer with 18 years of experience who blends deep cryptographic and distributed-systems expertise with a playful leadership role as CCO of LaffQ.com in Las Vegas. With a strong academic foundation in mathematics (BSc and MA), he has made impactful open-source contributions to notable projects like pycoin and the Chia blockchain, improving signature hashing, segwit handling, and core integer/versioning robustness. He has a proven track record of modernizing legacy codebases—porting BitTorrent DHT tooling to asyncio and refactoring for performance and reliability. Colleagues rely on him for pragmatic, low-level problem solving around cryptography, networking, and async architectures. Known to enjoy donuts and a relaxed attitude, he pairs that levity with rigorous attention to correctness and performance in production systems.
