What I'm Doing Now

  • Building GenAI systems @ Walmart
  • Solving safe exploitation @ Mieza
  • Grounding LLMs in GTO policies @ Mieza

What I was doing previously

Today I split my time between two arenas. As a Principal Software Engineer at Walmart I build generative‑AI systems that must be safe, reliable, and cost‑effective at retail scale. As CEO and sole engineer at Mieza, I build game‑theoretic AI -- solvers that compute provably optimal strategies for domains with hidden information and adversarial dynamics.

<p>Previously I built experimentation platforms at <a href="https://developer.amazon.com/alexa" target="_blank" rel="noopener">Amazon Alexa</a>, enabling fast, trustworthy product iteration. Before that I worked at <a href="https://ai.meta.com/" target="_blank" rel="noopener">Meta</a> on at‑scale machine learning over pixel data. Earlier in my career I shipped award‑recognized, production‑grade platforms with <a href="https://www.snapone.com/" target="_blank" rel="noopener">Pakedge</a> and <a href="https://www.control4.com/" target="_blank" rel="noopener">Control4</a> (including a <a href="https://www.commercialintegrator.com/awards/ci-best-awards/" target="_blank" rel="noopener">CI BEST Award</a>) and helped keep Pakedge at the top of the <a href="https://www.cepro.com/brands/brand-analysis/" target="_blank" rel="noopener">CE Pro Brand Leader</a> list for multiple years.</p>
