  • 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.

Previously I built experimentation platforms at Amazon Alexa, enabling fast, trustworthy product iteration. Before that I worked at Meta on at‑scale machine learning over pixel data. Earlier in my career I shipped award‑recognized, production‑grade platforms with Pakedge and Control4 (including a CI BEST Award) and helped keep Pakedge at the top of the CE Pro Brand Leader list for multiple years.
