Rockstar🎓
Top SchoolLuke Dashjr is a veteran software engineer and long-time Bitcoin Core contributor with over 28 years of programming experience and more than a decade of continuous, high-impact work on Bitcoin since 2011. As Chairman, CTO, and co-founder of OCEAN and creator of the OCEAN mining pool, he blends protocol-level development with hands-on mining infrastructure design and pool reward-system research. He has led and maintained critical open-source projects (including BFGMiner/cgminer and Bitcoin Core components), authored the getblocktemplate standard (BIP 22/23), and contributed low-level cryptographic and performance optimizations to secp256k1 and other core libraries. His work spans full-stack blockchain engineering—from wallet and RPC improvements to GUI tweaks and mining protocol implementations—demonstrating rare depth across network, consensus, and wallet internals. Notably, he has driven multi-wallet support, deterministic distributions, and miner-focused optimizations that materially improved network security and deployability. Based in Greater Tampa Bay, he is available for contract or hire and actively seeks sponsorship to continue public Bitcoin development.
