Full-stack engineer, infrastructure operator, and founder with 20+ years across the U.S. Navy/DoD, enterprise IT, and my own companies. I ship production systems end to end, from the servers and networks to the apps people use: a crypto social platform with native iOS and Android apps; self-hosted AI on company-owned GPUs (local LLMs, retrieval-augmented generation, image generation); Solana programs and a proprietary 32-chain market-data indexer; an Unreal Engine 5 multiplayer game running on nine dedicated servers; and a hosting company managing 350+ domains. DoD background supporting 50+ T-6B flight-simulator training devices. I own the whole stack, including the 3 AM fixes.
