the elevator pitch.

The next trillion-dollar consumer isn't human. AI agents are the new buyers — they browse, compare, decide, and transact on behalf of people who've stopped clicking. But every storefront, schema, and search index on the internet was built for human habits. I build the infrastructure that translates between the old web and the new buyers — knowledge freshness, structured authority, and agentic-readable surfaces — so brands don't get filtered out of the conversation before the conversation starts.

where I've shown up.

Co-Founder & CTO
Wrodium
2024 → NOW
Berkeley, CA · Berkeley SkyDeck Batch 21 · Most Innovative Technology Award
  • Co-founded and lead engineering at the GEO and knowledge freshness infrastructure company. Closing a $1.5M pre-seed at a $15M post-money SAFE cap with Verdict Capital, 359 Capital, Harlem Capital, and The House Fund.
  • Architected the full product surface: Living Articles, the Semantic Resonance Engine, ClawdBot/OpenClaw, Wrodium Roast, and the WebMCP infrastructure layer.
  • Designed a proprietary revenue-weighted GEO measurement framework — Conversion Potential Score, Prompt-to-Revenue Velocity, AI Traffic CAC, LTV of AI Customers. Turned GEO from a visibility game into measurable dollar attribution across ChatGPT, Gemini, Perplexity, and Claude.
  • Shipped client wins across Quotr, Robin Woolard Designs, Aparti, ScamAI/Reality Inc., Multiplier — entity disambiguation on Wikidata, schema rollouts, llms.txt, citation tracking on Cloudflare AI Zone exports.
  • Built the GTM machine end-to-end: 17-inbox cold outbound on Instantly, Apollo prospecting, SAFE workflow, Delaware franchise filings, Notion data room, the Supabase → InsForge migration.
  • Positioned Wrodium against Profound, Peec AI, AthenaHQ, Relixir in a market growing at 34% CAGR.
Undergraduate Researcher
Hearst Lab, UC Berkeley
2024 → NOW
Advised by Prof. Marti Hearst · NLP & Information Retrieval
  • Co-authored GEO-16 (arXiv:2509.10762) — a 16-task benchmark for evaluating generative engine optimization across modern LLM-backed search systems.
  • Co-authored CHASE, submitted to COLM 2026, on knowledge freshness and citation behavior in retrieval-augmented LLMs.
  • Produced a Lean 4 formalization of GEO-16 for CS 294-268 — bridging empirical NLP findings with machine-checked proofs.
  • In discussions with CalCompute (UC public compute cluster authorized under California SB 53; framework report due Jan 1, 2027) to develop knowledge-freshness infrastructure for legally compliant, auditable AI under emerging California public-sector AI policy.
Founder
Air Quake Simulations
ACQUIRED
VR flight simulator hardware · Founded at 19
  • Founded and exited a VR flight simulator hardware company building F-18 cockpit systems for pilots and sim enthusiasts. Shipped hundreds of units before acquisition.
  • Designed and 3D-printed cockpit components that undercut the industry by 10× — opened pro-grade flight sim hardware to a previously priced-out market.
  • Engineered an AI-powered VR training platform in Python + PyTorch with reinforcement learning, real-time adaptive feedback, and GPU-accelerated pipelines integrated with Unity3D environments.
003

the academic part.

B.A. Computer Science, Data Science & Economics
UC Berkeley
SPRING 2026
  • Research projects on AI deepfakes as an epistemological break from historical deception patterns, econometric analysis, and ML theory.

ask my llms.txt.

Live · Claude API · No backend
Claude, grounded in my /llms.txt

This is a real Anthropic API call made directly from your browser. The model receives my live llms.txt as its system prompt and answers as my AI representative. Bring your own key — it stays in your browser's sessionStorage and never touches a server I control.

model: claude-haiku-4-5 · grounded in /llms.txt · endpoint: /api/ask
🔒 The Anthropic API key lives only on the server. Your question is POSTed to /api/ask (a Vercel serverless function), which forwards it to api.anthropic.com with /llms.txt injected as the system prompt. TODO: deploy the matching api/ask.js handler — see the template at the bottom of this file's <script>.

The Ad-ification of AI: When Chatbots Become Salespeople
CITRIS · Center for Information Technology Research in the Interest of Society, UC Berkeley
Examined the integration of paid advertising into conversational AI systems, the trust and design tradeoffs of AI-embedded ads, and the regulatory boundaries emerging across OpenAI, Google, Perplexity, and Anthropic.
