HCI at the model boundary
ThinkVoice: Grok Voice + sensing hardware so people can converse without moving their mouths. Context-aware reply chips, blink/nod select, Watch + Health. Assistive, not a demo toy.

@Daniel_Farinax·Washington, D.C.
I ship free AI-native products in public — agents, voice, browsers, games — then take the same loop into hard HCI. 3rd at the SpaceXAI Grokathon (most users). Looking for a seat at a large AI lab.

What I want you to see
I am capable. Most of it lives in public threads and shipped apps — not a résumé. This page is the packet.
Agents that finish systems
GrokTerm, Unity C# with MCP, 3,500-line 3D games. I push models through full products — PTY, voice, editor tooling — not chat snippets.
Security instincts
HackerOne Researcher of the Month, selected by the Department of Defense, for critical reports. White-hat curiosity is how I think about systems.
Public distribution
Viral posts, more than 100 million combined views in recent months. A community at chat.grok.me. I can ship and I can show.
Latest highlight
3rd at SpaceXAI Grokathon
ThinkVoice · San Francisco · 12 hours · Aug 8, 2026
Official 3rd place from @SpaceXAI — and the award for most users. We built ThinkVoice: speak without moving your mouth by combining Grok Voice with brain-sensing. The model understands the conversation, suggests what you might say next, and you select with a nod, blink, or shake.
Team: @yangchasiu, @elithpalomino, @Daniel_Farinax. Top 6, then podium. Recap video and full write-up live.

If you are hiring builders who ship
I want to work on frontier models, agents, voice, and the interfaces that make them usable. D.C. based, will travel. Community is at chat.grok.me — or just write me on X.
