Duke Leto is a seasoned core developer and founder with 24 years of engineering experience specializing in privacy-focused cryptocurrencies, decentralized exchange protocols, and cryptographic primitives. He advises and delivers custom development for Bitcoin, Monero, Zcash and other privacy coins, charging premium consulting rates paid in BTC/XMR, and has led core contributions to notable projects such as Zcash and Komodo. As founder of Leto Labs and a long-time contributor to open source (GitHub bio: Free + Open Source Citizen), he blends deep systems skills—Perl, Python, Linux, PostgreSQL—and test-driven engineering with protocol-level crypto work like zkSNARKs and delayed PoW. He has a track record of improving critical infrastructure and tooling—wallet/RPC fixes in Zcash, test and CI enhancements for CASH Music and Travis CI, and debugger improvements for the Parrot VM—showing attention to both correctness and developer experience. With an MS in Mathematics and a history of running community initiatives (founding the world’s first Git user group), he pairs rigorous academic reasoning with practical, production-grade software delivery. An often-overlooked strength is his ability to translate complex crypto research into deployable, well-tested code and operational workflows.
