Engineering Portfolio & Selected Case Studies
Each project below distinguishes verified offline implementation from prototype or gated capabilities.
Hovis Local AI Workbench
Role: Creator, Systems Architect, & Product Owner
Most personal AI assistants require sending private documents to cloud APIs, lack deterministic budget/scope boundaries, and cannot recover cleanly when a local worker restarts.
Stack: Node.js v24, RFC 8785 JCS, SHA-256 Hash-Chained Ledger, Local Loopback HTTP API (127.0.0.1:41435), Portable Ollama Target (127.0.0.1:11435).
Evidence: Verified across 13 offline contract and regression test suites (143 passed, 0 failed, 0 network sockets opened).
Cultural AI & Isolated Local Ancestry Viewer
Role: Product Designer & Privacy Architecture Lead
Built an opt-in Cultural AI profile engine requiring explicit two-step owner confirmation before storing any fact, per-task personalization previews with opt-out, zero-hallucination career drafting, local Kanban boards, and a completely separate encrypted vault for user-selected 23andMe exports.
Hovis Fluid Atelier (WebGL2 Interactive Studio)
Role: Creative Technologist & UI Architect
Created an isolated client-side WebGL2 fluid art studio with configurable physics/dye grids, non-persisting and persisting brush modes, stroke undo history, and OLED black canvas presets.
