CAVOK Designs is a specialized engineering shop based on the Space Coast in Melbourne, FL. Founded by John Tubbert—a professional pilot, flight instructor, and hardware-first systems builder—we build local, private, and offline-capable AI systems for professionals who handle high-consequence data. We do not build generic API wrappers, and we do not sell recurring software-as-a-service (SaaS) subscriptions. We write software that runs on your physical hardware, giving you complete sovereignty over your data. What We Do We specialize in deploying secure, high-performance artificial intelligence environments directly onto your own infrastructure: Sovereign RAG Engines: We ingest and index proprietary manuals, flight books, technical schematics, and databases into secure local vector stores. Your documents are searchable offline and never touch a public cloud server. Offline AI Agents: We deploy local task-execution loops that run securely inside sandboxed environments on your network. These agents monitor files, compile technical reports, and execute system commands completely offline. Hardware & Model Optimization: We audit, configure, and tune open-source LLMs to match the specific physical limits of your workstations—such as dedicated macOS systems or multi-GPU Linux machines. Why Clients Choose Us Absolute Privacy: We design setups where data leakage is physically impossible. If you operate under strict ITAR, aviation safety, medical, or corporate compliance rules, our local-first approach is your only secure path. Zero Subscription Fees: You buy the setup or the deployment once. You run it on your own metal forever. No monthly API charges, seat costs, or unexpected invoices. Operational Proof: We build and test our systems on our own bare-metal development workstation
